1.2.2
V2 Core Overview
The version 2 ColdFire processor core is comprised of two separate pipelines decoupled by an instruction buffer. The two-stage instruction fetch pipeline (IFP) is responsible for instruction-address generation and instruction fetch. The instruction buffer is a first-in-first-out (FIFO) buffer that holds prefetched instructions awaiting execution in the operand execution pipeline (OEP). The OEP includes two pipeline stages. The first stage decodes instructions and selects operands (DSOC); the second stage (AGEX) performs instruction execution and calculates operand effective addresses, if needed. The V2 core implements the ColdFire instruction set architecture revision A+ with support for a separate user stack pointer register and four new instructions to assist in bit processing. Additionally, the core includes the enhanced multiply-accumulate (EMAC) unit for improved signal processing capabilities. The EMAC implements a three-stage arithmetic pipeline, optimized for 32x32 bit operations, with support for four 48-bit accumulators. Supported operands include 16- and 32-bit signed and unsigned integers, signed fractional operands, and a complete set of instructions to process these data types. The EMAC provides support for execution of DSP operations within the context of a single processor at a minimal hardware cost.
1.2.3
Integrated Debug Module
The ColdFire processor core debug interface is provided to support system debugging with low-cost debug and emulator development tools. Through a standard debug interface, access to debug information and real-time tracing capability is provided on 144-lead packages. This allows the processor and system to be debugged at full speed without the need for costly in-circuit emulators. The on-chip breakpoint resources include a total of nine programmable 32-bit registers: an address and an address mask register, a data and a data mask register, four PC registers, and one PC mask register. These registers can be accessed through the dedicated debug serial communication channel or from the processor's supervisor mode programming model. The breakpoint registers can be configured to generate triggers by combining the address, data, and PC conditions in a variety of single- or dual-level definitions. The trigger event can be programmed to generate a processor halt or initiate a debug interrupt exception. This device implements revision B+ of the ColdFire Debug Architecture. The processor's interrupt servicing options during emulator mode allow real-time critical interrupt service routines to be serviced while processing a debug interrupt event. This ensures the system continues to operate even during debugging. To support program trace, the V2 debug module provides processor status (PST[3:0]) and debug data (DDATA[3:0]) ports. These buses and the PSTCLK output provide execution status, captured operand data, and branch target addresses defining processor activity at the CPU's clock rate. The device includes a new debug signal, ALLPST. This signal is the logical AND of the processor status (PST[3:0]) signals and is useful for detecting when the processor is in a halted state (PST[3:0] = 1111). The full debug/trace interface is available only on the 144-pin packages. However, every product features the dedicated debug serial communication channel (DSI, DSO, DSCLK) and the ALLPST signal.
1.2.4
JTAG
The processor supports circuit board test strategies based on the Test Technology Committee of IEEE and the Joint Test Action Group (JTAG). The test logic includes a test access port (TAP) consisting of a 16-state controller, an instruction register, and three test registers (a 1-bit bypass register, a boundary-scan register, and a 32-bit ID register). The boundary scan register links the device's pins into one shift register. Test logic, implemented using static logic design, is independent of the device system logic. The device implementation can: * * * * * Perform boundary-scan operations to test circuit board electrical continuity Sample system pins during operation and transparently shift out the result in the boundary scan register Bypass the device for a given circuit board test by effectively reducing the boundary-scan register to a single bit Disable the output drive to pins during circuit-board testing Drive output pins to stable levels

1.2.5.1
On-Chip Memories
SRAM
The dual-ported SRAM module provides a general-purpose 64-Kbyte memory block that the ColdFire core can access in a single cycle. The location of the memory block can be set to any 64-Kbyte boundary within the 4-Gbyte address space. This memory is ideal for storing critical code or data structures and for use as the system stack. Because the SRAM module is physically connected to the processor's high-speed local bus, it can quickly service core-initiated accesses or memory-referencing commands from the debug module. The SRAM module is also accessible by the DMA, FEC, and USB. The dual-ported nature of the SRAM makes it ideal for implementing applications with double-buffer schemes, where the processor and a DMA device operate in alternate regions of the SRAM to maximize system performance.
1.2.5.2
Flash Memory
The ColdFire flash module (CFM) is a non-volatile memory (NVM) module that connects to the processor's high-speed local bus. The CFM is constructed with four banks of 64-Kbytex16-bit flash memory arrays to generate 512 Kbytes of 32-bit flash memory. These electrically erasable and programmable arrays serve as non-volatile program and data memory. The flash memory is ideal for program and data storage for single-chip applications, allowing for field reprogramming without requiring an external high voltage source. The CFM interfaces to the ColdFire core through an optimized read-only memory controller that supports interleaved accesses from the 2-cycle flash memory arrays. A backdoor mapping of the flash memory is used for all program, erase, and verify operations, as well as providing a read datapath for the DMA. Flash memory may also be programmed via the EzPort, which is a serial flash memory programming interface that allows the flash memory to be read, erased and programmed by an external controller in a format compatible with most SPI bus flash memory chips.
1.2.6
Cryptographic Acceleration Unit
The MCF52235 device incorporates two hardware accelerators for cryptographic functions. First, the CAU is a coprocessor tightly-coupled to the V2 ColdFire core that implements a set of specialized operations to increase the throughput of software-based encryption and message digest functions, specifically the DES, 3DES, AES, MD5 and SHA-1 algorithms. Second, a random number generator provides FIPS-140 compliant 32-bit values to security processing routines. Both modules supply critical acceleration to software-based cryptographic algorithms at a minimal hardware cost.
1.2.7
Power Management
The device incorporates several low-power modes of operation entered under program control and exited by several external trigger events. An integrated power-on reset (POR) circuit monitors the input supply and forces an MCU reset as the supply voltage rises. The low voltage detector (LVD) monitors the supply voltage and is configurable to force a reset or interrupt condition if it falls below the LVD trip point. The RAM standby switch provides power to RAM when the supply voltage to the chip falls below the standby battery voltage.
1.2.8
FlexCAN
The FlexCAN module is a communication controller implementing version 2.0 of the CAN protocol parts A and B. The CAN protocol can be used as an industrial control serial data bus, meeting the specific requirements of reliable operation in a harsh EMI environment with high bandwidth. This instantiation of FlexCAN has 16 message buffers.

1.2.9
Mini-FlexBus
A multi-function external bus interface called the Mini-FlexBus is provided on the device with basic functionality of interfacing to slave-only devices with a maximum slave bus frequency up to 40 MHz in 1:2 mode and 80 MHz in 1:1 mode. It can be directly connected to the following asynchronous or synchronous devices with little or no additional circuitry: * * * * External ROMs Flash memories Gate-array logic Other simple target (slave) devices
The Mini-FlexBus is a subset of the FlexBus module found on higher-end ColdFire microprocessors. The Mini-FlexBus minimizes package pin-outs while maintaining a high level of configurability and functionality.
1.2.10
USB On-The-Go Controller
The device includes a Universal Serial Bus On-The-Go (USB OTG) dual-mode controller. USB is a popular standard for connecting peripherals and portable consumer electronic devices such as digital cameras and handheld computers to host PCs. The OTG supplement to the USB specification extends USB to peer-to-peer application, enabling devices to connect directly to each other without the need for a PC. The dual-mode controller on the device can act as a USB OTG host and as a USB device. It also supports full-speed and low-speed modes.
1.2.11
Fast Ethernet Controller (FEC)
The Ethernet media access controller (MAC) supports 10 and 100 Mbps Ethernet/IEEE 802.3 networks. An external transceiver interface and transceiver function are required to complete the interface to the media. The FEC supports three different standard MAC-PHY (physical) interfaces for connection to an external Ethernet transceiver. The FECs supports the 10/100 Mbps MII, and the 10 Mbps-only 7-wire interface.
1.2.12
UARTs
The device has three full-duplex UARTs that function independently. The three UARTs can be clocked by the system bus clock, eliminating the need for an external clock source. On smaller packages, the third UART is multiplexed with other digital I/O functions.
1.2.13
I2C Bus
The processor includes two I2C modules. The I2C bus is an industry-standard, two-wire, bidirectional serial bus that provides a simple, efficient method of data exchange and minimizes the interconnection between devices. This bus is suitable for applications requiring occasional communications over a short distance between many devices.
1.2.14
QSPI
The queued serial peripheral interface (QSPI) provides a synchronous serial peripheral interface with queued transfer capability. It allows up to 16 transfers to be queued at once, minimizing the need for CPU intervention between transfers.
1.2.15
Fast ADC
The fast ADC consists of an eight-channel input select multiplexer and two independent sample and hold (S/H) circuits feeding separate 12-bit ADCs. The two separate converters store their results in accessible buffers for further processing. Signals on the SYNCA and SYNCB pins initiate an ADC conversion.
MCF52259 ColdFire Microcontroller, Rev. 0 12 Freescale Semiconductor
Family Configurations
The ADC can be configured to perform a single scan and halt, a scan when triggered, or a programmed scan sequence repeatedly until manually stopped. The ADC can be configured for sequential or simultaneous conversion. When configured for sequential conversions, up to eight channels can be sampled and stored in any order specified by the channel list register. Both ADCs may be required during a scan, depending on the inputs to be sampled. During a simultaneous conversion, both S/H circuits are used to capture two different channels at the same time. This configuration requires that a single channel may not be sampled by both S/H circuits simultaneously. Optional interrupts can be generated at the end of the scan sequence if a channel is out of range (measures below the low threshold limit or above the high threshold limit set in the limit registers) or at several different zero crossing conditions.
1.2.16
DMA Timers (DTIM0-DTIM3)
There are four independent, DMA transfer capable 32-bit timers (DTIM0, DTIM1, DTIM2, and DTIM3) on the device. Each module incorporates a 32-bit timer with a separate register set for configuration and control. The timers can be configured to operate from the system clock or from an external clock source using one of the DTINn signals. If the system clock is selected, it can be divided by 16 or 1. The input clock is further divided by a user-programmable 8-bit prescaler that clocks the actual timer counter register (TCRn). Each of these timers can be configured for input capture or reference (output) compare mode. Timer events may optionally cause interrupt requests or DMA transfers.
1.2.17
General Purpose Timer (GPT)
The general purpose timer (GPT) is a four-channel timer module consisting of a 16-bit programmable counter driven by a seven-stage programmable prescaler. Each of the four channels can be configured for input capture or output compare. Additionally, channel three, can be configured as a pulse accumulator. A timer overflow function allows software to extend the timing capability of the system beyond the 16-bit range of the counter. The input capture and output compare functions allow simultaneous input waveform measurements and output waveform generation. The input capture function can capture the time of a selected transition edge. The output compare function can generate output waveforms and timer software delays. The 16-bit pulse accumulator can operate as a simple event counter or a gated time accumulator.
1.2.18
Periodic Interrupt Timers (PIT0 and PIT1)
The two periodic interrupt timers (PIT0 and PIT1) are 16-bit timers that provide interrupts at regular intervals with minimal processor intervention. Each timer can count down from the value written in its PIT modulus register or it can be a free-running down-counter.
1.2.19
Real-Time Clock (RTC)
The Real-Time Clock (RTC) module maintains the system (time-of-day) clock and provides stopwatch, alarm, and interrupt functions. It includes full clock features: seconds, minutes, hours, days and supports a host of time-of-day interrupt functions along with an alarm interrupt.
1.2.20
Pulse-Width Modulation (PWM) Timers
The device has an 8-channel, 8-bit PWM timer. Each channel has a programmable period and duty cycle as well as a dedicated counter. Each of the modulators can create independent continuous waveforms with software-selectable duty rates from 0% to 100%. The timer supports PCM mode, which results in superior signal quality when compared to that of a conventional PWM. The PWM outputs have programmable polarity, and can be programmed as left aligned outputs or center aligned outputs. For

higher period and duty cycle resolution, each pair of adjacent channels ([7:6], [5:4], [3:2], and [1:0]) can be concatenated to form a single 16-bit channel. The module can, therefore, be configured to support 8/0, 6/1, 4/2, 2/3, or 0/4 8-/16-bit channels.
1.2.21
Software Watchdog Timer
The watchdog timer is a 32-bit timer that facilitates recovery from runaway code. The watchdog counter is a free-running down-counter that generates a reset on underflow. To prevent a reset, software must periodically restart the countdown.
1.2.22
Backup Watchdog Timer
The backup watchdog timer is an independent 16-bit timer that, like the software watchdog timer, facilitates recovery from runaway code. This timer is a free-running down-counter that generates a reset on underflow. To prevent a reset, software must periodically restart the countdown. The backup watchdog timer can be clocked by either the relaxation oscillator or the system clock.
1.2.23
Phase-Locked Loop (PLL)
The clock module contains a crystal oscillator, 8 MHz on-chip relaxation oscillator (OCO), phase-locked loop (PLL), reduced frequency divider (RFD), low-power divider status/control registers, and control logic. To improve noise immunity, the PLL, crystal oscillator, and relaxation oscillator have their own power supply inputs: VDDPLL and VSSPLL. All other circuits are powered by the normal supply pins, VDD and VSS.
1.2.24
Interrupt Controllers (INTCn)
The device has two interrupt controllers that supports up to 128 interrupt sources. There are 56 programmable sources, 49 of which are assigned to unique peripheral interrupt requests. The remaining seven sources are unassigned and may be used for software interrupt requests.
1.2.25
DMA Controller
The direct memory access (DMA) controller provides an efficient way to move blocks of data with minimal processor intervention. It has four channels that allow byte, word, longword, or 16-byte burst line transfers. These transfers are triggered by software explicitly setting a DCRn[START] bit or by the occurrence of certain UART or DMA timer events.
1.2.26
* * * * * * *
Reset
The reset controller determines the source of reset, asserts the appropriate reset signals to the system, and keeps track of what caused the last reset. There are seven sources of reset: External reset input Power-on reset (POR) Watchdog timer Phase locked-loop (PLL) loss of lock / loss of clock Software Low-voltage detector (LVD) JTAG
Control of the LVD and its associated reset and interrupt are managed by the reset controller. Other registers provide status flags indicating the last source of reset and a control bit for software assertion of the RSTO pin.

GPIO
Nearly all pins on the device have general purpose I/O capability and are grouped into 8-bit ports. Some ports do not use all eight bits. Each port has registers that configure, monitor, and control the port pin.

The PDSR and PSSR registers are described in the General Purpose I/O chapter. All programmable signals default to 2 mA drive and FAST slew rate in normal (single-chip) mode. All signals have a pull-up in GPIO mode. These signals are multiplexed on other pins. For primary and GPIO functions only. Only when JTAG mode is enabled. CLKMOD0 and CLKMOD1 have internal pull-down resistors; however, the use of external resistors is very strongly recommended. For secondary and GPIO functions only. RSTI has an internal pull-up resistor; however, the use of an external resistor is very strongly recommended. For GPIO function. Primary Function has pull-up control within the GPT module.

Electrical Characteristics
This section contains electrical specification tables and reference timing diagrams for the microcontroller unit, including detailed information on power considerations, DC/AC electrical characteristics, and AC timing specifications. The electrical specifications are preliminary and are from previous designs or design simulations. These specifications may not be fully tested or guaranteed at this early stage of the product life cycle. These specifications will, however, be met for production silicon. Finalized specifications will be published after complete characterization and device qualifications have been completed.
NOTE
The parameters specified in this data sheet supersede any values found in the module specifications.

Functional operating conditions are given in DC Electrical Specifications. Absolute Maximum Ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress beyond those listed may affect device reliability or cause permanent damage to the device. This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, it is advised that normal precautions be taken to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (VSS or VDD). Input must be current limited to the IDD value specified. To determine the value of the required current-limiting resistor, calculate resistance values for positive and negative clamp voltages, then use the larger of the two values. All functional non-supply pins are internally clamped to VSS and VDD. The power supply must maintain regulation within operating VDD range during instantaneous and operating maximum current conditions. If positive injection current (Vin > VDD) is greater than IDD, the injection current may flow out of VDD and could result in the external power supply going out of regulation. Ensure that the external VDD load shunts current greater than maximum injection current. This is the greatest risk when the MCU is not consuming power (e.g., no clock). Depending on the packaging; see the orderable part number summary.

Thermal resistance between the die and the printed circuit board in conformance with JEDEC JESD51-8. Board temperature is measured on the top surface of the board near the package. 17 Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883 Method 1012.1). 18 Thermal characterization parameter indicating the temperature difference between package top and the junction temperature per JEDEC JESD51-2. When Greek letters are not available, the thermal characterization parameter is written in conformance with Psi-JT. The average chip-junction temperature (TJ) in C can be obtained from: T J = T A + ( P D x JMA ) (1) Where: TA JA PD PINT PI/O = ambient temperature, C = package thermal resistance, junction-to-ambient, C/W = PINT + PI/O = chip internal power, IDD x VDD, watts = power dissipation on input and output pins -- user determined, watts
For most applications PI/O < PINT and can be ignored. An approximate relationship between PD and TJ (if PI/O is neglected) is: P D = K / ( T J + 273C ) Solving equations 1 and 2 for K gives: K = PD x (TA + 273 C) + JMA x PD 2 (3) where K is a constant pertaining to the particular part. K can be determined from equation (3) by measuring PD (at equilibrium) for a known TA. Using this value of K, the values of PD and TJ can be obtained by solving equations (1) and (2) iteratively for any value of TA. (2)

In external clock mode, it is possible to run the chip directly from an external clock source without enabling the PLL. All internal registers retain data at 0 Hz. 3 Depending on packaging; see Table 12. 4 Loss of Reference Frequency is the reference frequency detected internally, which transitions the PLL into self clocked mode. 5 Self clocked mode frequency is the frequency at which the PLL operates when the reference frequency falls below f LOR with default MFD/RFD settings. 6 This parameter is characterized before qualification rather than 100% tested. 7 Proper PC board layout procedures must be followed to achieve specifications. 8 This specification applies to the period required for the PLL to relock after changing the MFD frequency control bits in the synthesizer control register (SYNCR). 9 Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f . sys Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise injected into the PLL circuitry via VDDPLL and VSSPLL and variation in crystal oscillator frequency increase the Cjitter percentage for a given interval. 10 Based on slow system clock of 40 MHz measured at f sys max.

Mini-FlexBus External Interface Specifications
A multi-function external bus interface called Mini-FlexBus is provided with basic functionality to interface to slave-only devices up to a maximum bus frequency of 80MHz. It can be directly connected to asynchronous or synchronous devices such as external boot ROMs, flash memories, gate-array logic, or other simple target (slave) devices with little or no additional circuitry. For asynchronous devices a simple chip-select based interface can be used. All processor bus timings are synchronous; that is, input setup/hold and output delay are given in respect to the rising edge of a reference clock, MB_CLK. The MB_CLK frequency is half the internal system bus frequency. The following timing numbers indicate when data is latched or driven onto the external bus, relative to the Mini-FlexBus output clock (MB_CLK). All other timing relationships can be derived from these values.

Output numbers depend on the value programmed into the IFDR; an IFDR programmed with the maximum frequency (IFDR = 0x20) results in minimum output timings as shown in Table 25. The I2C interface is designed to scale the actual data transition time to move it to the middle of the SCL low period. The actual position is affected by the prescale and division values programmed into the IFDR; however, the numbers given in Table 25 are minimum values. 2 Because SCL and SDA are open-collector-type outputs, which the processor can only actively drive low, the time SCL or SDA take to reach a high level depends on external signal capacitance and pull-up resistor values. 3 Specified at a nominal 50-pF load.

Equivalent Circuit for ADC Inputs
Figure 10-17 shows the ADC input circuit during sample and hold. S1 and S2 are always open/closed at the same time that S3 is closed/open. When S1/S2 are closed & S3 is open, one input of the sample and hold circuit moves to (VREFH-VREFL)/2, while the other charges to the analog input voltage. When the switches are flipped, the charge on C1 and C2 are averaged via S3, with the result that a single-ended analog input is switched to a differential voltage centered about (VREFH-VREFL)/2. The switches switch on every cycle of the ADC clock (open one-half ADC clock, closed one-half ADC clock). There are additional capacitances associated with the analog input pad, routing, etc., but these do not filter into the S/H output voltage, as S1 provides isolation during the charge-sharing phase. One aspect of this circuit is that there is an on-going input current, which is a function of the analog input voltage, VREF and the ADC clock frequency.
