1.2 56854 Description
The 56854 is a member of the 56800E core-based family of controllers. It combines, on a single chip, the processing power of a Digital Signal Processor (DSP) and the functionality of a microcontroller with a flexible set of peripherals to create an extremely cost-effective solution. Because of its low cost, configuration flexibility, and compact program code, the 56854 is well-suited for many applications. The 56854 includes many peripherals that are especially useful for low-end Internet appliance applications and low-end client applications such as telephony; portable devices; Internet audio; and point-of-sale systems, such as noise suppression; ID tag readers; sonic/subsonic detectors; security access devices; remote metering; sonic alarms. The 56800E core is based on a Harvard-style architecture consisting of three execution units operating in parallel, allowing as many as six operations per instruction cycle. The microprocessor-style programming model and optimized instruction set allow straightforward generation of efficient, compact DSP and control code. The instruction set is also highly efficient for C Compilers, enabling rapid development of optimized control applications. The 56854 supports program execution from either internal or external memories. Two data operands can be accessed from the on-chip Data RAM per instruction cycle. The 56854 also provides two external dedicated interrupt lines, and up to 41 General Purpose Input/Output (GPIO) lines, depending on peripheral configuration. The 56854 controller includes 16K words of Program RAM, 16K words of Data RAM, and 1K words of Boot ROM. It also supports program execution from external memory. This controller also provides a full set of standard programmable peripherals that include an 8-bit parallel Host Interface, Enhanced Synchronous Serial Interface (ESSI), one Serial Peripheral Interface (SPI), two Serial Communications Interfaces (SCIs), and a Quad Timer. The Host Interface, ESSI, SPI, SCI, four chip selects and quad timer can be used as General Purpose Input/Outputs (GPIOs) if its primary function is not required.

SC02 is the frame sync for both the transmitter and receiver in synchronous mode and for the transmitter only in asynchronous mode. When configured as an output, this pin is the internally generated frame sync signal. When configured as an input, this pin receives an external frame sync signal for the transmitter (and the receiver in synchronous operation). Port C GPIO (5)--This pin is a General Purpose I/O (GPIO) pin when the ESSI is not in use. SPI Master In/Slave Out (MISO)--This serial data pin is an input to a master device and an output from a slave device. The MISO line of a slave device is placed in the high-impedance state if the slave device is not selected. The driver on this pin can be configured as an open-drain driver by the SPI's Wired-OR mode (WOM) bit when this pin is configured for SPI operation. Port F GPIO (0)--This pin is a General Purpose I/O (GPIO) pin that can be individually programmed as input or output pin. SPI Master Out/Slave In (MOSI)--This serial data pin is an output from a master device and an input to a slave device. The master device places data on the MOSI line a half-cycle before the clock edge that the slave device uses to latch the data. The driver on this pin can be configured as an open-drain driver by the SPI's WOM bit when this pin is configured for SPI operation. Port F GPIO (1)--This pin is a General Purpose I/O (GPIO) pin that can individually be programmed as input or output pin. SPI Serial Clock (SCK)--This bidirectional pin provides a serial bit rate clock for the SPI. This gated clock signal is an input to a slave device and is generated as an output by a master device. Slave devices ignore the SCK signal unless the SS pin is active low. In both master and slave SPI devices, data is shifted on one edge of the SCK signal and is sampled on the opposite edge, where data is stable. The driver on this pin can be configured as an open-drain driver by the SPI's WOM bit when this pin is configured for SPI operation. When using Wired-OR mode, the user must provide an external pull-up device. Port F GPIO (2)--This pin is a General Purpose I/O (GPIO) pin that can be individually programmed as input or output pin.

Introduction
Table 3-1. 56854 Signal and Package Information for the 128-pin LQFP (Continued)
Pin No. 4 Signal Name SS Type Input Description SPI Slave Select (SS)--This input pin selects a slave device before a master device can exchange data with the slave device. SS must be low before data transactions and must stay low for the duration of the transaction. The SS line of the master must be held high. Port F GPIO (3)--This pin is a General Purpose I/O (GPIO) pin that can individually be programmed as input or output pin. Crystal Oscillator Output (XTAL)--This output connects the internal crystal oscillator output to an external crystal. If an external clock source other than a crystal oscillator is used, XTAL must be used as the input. External Crystal Oscillator Input (EXTAL)--This input should be connected to an external crystal. If an external clock source other than a crystal oscillator is used, EXTAL must be tied off. See Section 4.5.2 Clock Output (CLKO)--This pin outputs a buffered clock signal. When enabled, this signal is the system clock divided by four. Test Clock Input (TCK)--This input pin provides a gated clock to synchronize the test logic and to shift serial data to the JTAG/Enhanced OnCE port. The pin is connected internally to a pull-down resistor. Test Data Input (TDI)--This input pin provides a serial input data stream to the JTAG/Enhanced OnCE port. It is sampled on the rising edge of TCK and has an on-chip pull-up resistor. Test Data Output (TDO)--This tri-statable output pin provides a serial output data stream from the JTAG/Enhanced OnCE port. It is driven in the Shift-IR and Shift-DR controller states, and changes on the falling edge of TCK. Test Mode Select Input (TMS)--This input pin is used to sequence the JTAG TAP controller's state machine. It is sampled on the rising edge of TCK and has an on-chip pull-up resistor. Note: Always tie the TMS pin to VDD through a 2.2K resistor.

Pin No. 50 Signal Name TRST Type Input Description Test Reset (TRST)--As an input, a low signal on this pin provides a reset signal to the JTAG TAP controller. To ensure complete hardware reset, TRST should be asserted whenever RESET is asserted. The only exception occurs in a debugging environment, since the Enhanced OnCE/JTAG module is under the control of the debugger. In this case it is not necessary to assert TRST when asserting RESET . Outside of a debugging environment RESET should be permanently asserted by grounding the signal, thus disabling the Enhanced OnCE/JTAG module on the device. Note: For normal operation, connect TRST directly to VSS. If the design is to be used in a debugging environment, TRST may be tied to VSS through a 1K resistor. 49 DE Input/Output Debug Event (DE)--This is an open-drain, bidirectional, active low signal. As an input, it is a means of entering debug mode of operation from an external command controller. As an output, it is a means of acknowledging that the chip has entered debug mode. This pin is connected internally to a weak pull-up resistor.

General Characteristics
Part 4 Specifications
4.1 General Characteristics
The 56854 is fabricated in high-density CMOS with 5-volt tolerant TTL-compatible digital inputs. The term "5-volt tolerant" refers to the capability of an I/O pin, built on a 3.3V compatible process technology, to withstand a voltage up to 5.5V without damaging the device. Many systems have a mixture of devices designed for 3.3V and 5V power supplies. In such systems, a bus may carry both 3.3V and 5V- compatible I/O voltage levels (a standard 3.3V I/O is designed to receive a maximum voltage of 3.3V 10% during normal operation without causing damage). This 5V tolerant capability therefore offers the power savings of 3.3V I/O levels while being able to receive 5V levels without being damaged. Absolute maximum ratings given in Table 4-1 are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond these ratings may affect device reliability or cause permanent damage to the device. The 56854 DC/AC electrical specifications are preliminary and are from design simulations. These specifications may not be fully tested or guaranteed at this early stage of the product life cycle. Finalized specifications will be published after complete characterization and device qualifications have been completed.
CAUTION
This device contains protective circuitry to guard against damage due to high static voltage or electrical fields. However, normal precautions are advised 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 voltage level.

Assumes clock source is direct clock to EXTAL or crystal oscillator running 2-4MHz. PLL must be enabled, locked, and selected. The actual frequency depends on the source clock frequency and programming of the CGM module. Master clock is derived from on of the following four sources: fclk = fxtal when the source clock is the direct clock to EXTAL fclk = fpll when PLL is selected fclk = fosc when the source clock is the crystal oscillator and PLL is not selected fclk = fextal when the source clock is the direct clock to EXTAL and PLL is not selected

While power is ramping up, this signal remains active for as long as the internal 2.5V is below 1.8V no matter how long the ramp up rate is. The internally regulated voltage is typically 100 mV less than VDD during ramp up until 2.5V is reached, at which time it self-regulates.

Time
Figure 4-2 Supply Voltage Sequencing and Separation Cautions VDD should not be allowed to rise early (1). This is usually avoided by running the regulator for the VDD supply (1.8V) from the voltage generated by the 3.3V VDDIO supply, see Figure 4-3. This keeps VDD from rising faster than VDDIO. VDD should not rise so late that a large voltage difference is allowed between the two supplies (2). Typically this situation is avoided by using external discrete diodes in series between supplies, as shown in Figure 4-3. The series diodes forward bias when the difference between VDDIO and VDD reaches approximately 2.1, causing VDD to rise as VDDIO ramps up. When the VDD regulator begins proper operation, the difference between supplies will typically be 0.8V and conduction through the diode chain reduces to essentially leakage current. During supply sequencing, the following general relationship should be adhered to: VDDIO > VDD > (VDDIO - 2.1V) In practice, VDDA is typically connected directly to VDDIO with some filtering.

4.5 External Clock Operation
The 56854 system clock can be derived from a crystal or an external system clock signal. To generate a reference frequency using the internal oscillator, a reference crystal must be connected between the EXTAL and XTAL pins.
4.5.1
Crystal Oscillator
The internal oscillator is designed to interface with a parallel-resonant crystal resonator in the frequency range specified for the external crystal in Table 4-6. In Figure 4-6 a typical crystal oscillator circuit is shown. Follow the crystal supplier's recommendations when selecting a crystal, because crystal parameters determine the component values required to provide maximum stability and reliable start-up. The crystal and associated components should be mounted as close as possible to the EXTAL and XTAL pins to minimize output distortion and start-up stabilization time.

1. An externally supplied reference clock should be as free as possible from any phase jitter for the PLL to work correctly. The PLL is optimized for 4MHz input crystal. 2. This is the minimum time required after the PLL setup is changed to ensure reliable operation.
4.6 External Memory Interface Timing
The External Memory Interface is designed to access static memory and peripheral devices. Figure 4-10 shows sample timing and parameters that are detailed in Table 4-11. The timing of each parameter consists of both a fixed delay portion and a clock related portion; as well as user controlled wait states. The equation: t = D + P * (M + W) should be used to determine the actual time of each parameter. The terms in the above equation are defined as: t P parameter delay time the period of the system clock, which determines the execution rate of the part (i.e. when the device is operating at 120 MHz, P = 8.33 ns). D fixed portion of the delay, due to on-chip path delays.
M Fixed portion of a clock period inherent in the design. This number is adjusted to account for possible clock duty cycle derating. W the sum of the applicable wait state controls. See the "Wait State Controls" column of Table 4-11 for the applicable controls for each parameter. See the EMI chapter of the 83x Peripheral Manual for details of what each wait state field controls. Some of the parameters contain two sets of numbers. These parameters have two different paths and clock edges that must be considered. Check both sets of numbers and use the smaller result. The appropriate entry may change if the operating frequency of the part changes. The timing of write cycles is different when WWS = 0 than when WWS > 0. Therefore, some parameters contain two sets of numbers to account for this difference. The "Wait States Configuration" column of Table 4-11 should be used to make the appropriate selection.

In the formulas, T = clock cycle. For fop = 120MHz operation and fipb = 60MHz, T = 8.33ns.
3. At reset, the PLL is disabled and bypassed. The part is then put into Run mode and tclk assumes the period of the source clock, txtal, textal or tosc. 4. The minimum is specified for the duration of an edge-sensitive IRQA interrupt required to recover from the Stop state. This is not the minimum required so that the IRQA interrupt is accepted. 5. 6. The interrupt instruction fetch is visible on the pins only in Mode 3. Fast stop mode:
Fast stop recovery applies when external clocking is in use (direct clocking to XTAL) or when fast stop mode recovery is requested (OMR bit 6 is set to 1). In both cases the PLL and the master clock are unaffected by stop mode entry. Recovery takes one less cycle and tclk will continue same value it had before stop mode was entered. 7. Normal stop mode: As a power saving feature, normal stop mode disables and bypasses the PLL. Stop mode will then shut down the master clock, recovery will take an extra cycle (to restart the clock), and tclk will resume at the input clock source rate. 8. ET = External Clock period, For an external crystal frequency of 8MHz, ET=125 ns.

Part 6 Design Considerations
6.1 Thermal Design Considerations
An estimation of the chip junction temperature, TJ, in C can be obtained from the equation:
Equation 1: TJ = TA + (PD x RJA)
Where:
TA = ambient temperature C RJA = package junction-to-ambient thermal resistance C/W PD = power dissipation in package
Historically, thermal resistance has been expressed as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance:
Equation 2: RJA = RJC + RCA
Where:
RJA = package junction-to-ambient thermal resistance C/W RJC = package junction-to-case thermal resistance C/W RCA = package case-to-ambient thermal resistance C/W
RJC is device-related and cannot be influenced by the user. The user controls the thermal environment to change the case-to-ambient thermal resistance, RCA. For example, the user can change the air flow around the device, add a heat sink, change the mounting arrangement on the Printed Circuit Board (PCB), or otherwise change the thermal dissipation capability of the area surrounding the device on the PCB. This model is most useful for ceramic packages with heat sinks; some 90% of the heat flow is dissipated through the case to the heat sink and out to the ambient environment. For ceramic packages, in situations where the heat flow is split between a path to the case and an alternate path through the PCB, analysis of the device thermal performance may need the additional modeling capability of a system level thermal simulation tool. The thermal performance of plastic packages is more dependent on the temperature of the PCB to which the package is mounted. Again, if the estimations obtained from RJA do not satisfactorily answer whether the thermal performance is adequate, a system level model may be appropriate. A complicating factor is the existence of three common definitions for determining the junction-to-case thermal resistance in plastic packages:
* Measure the thermal resistance from the junction to the outside surface of the package (case) closest to the chip mounting area when that surface has a proper heat sink. This is done to minimize temperature variation across the surface. Measure the thermal resistance from the junction to where the leads are attached to the case. This definition is approximately equal to a junction to board thermal resistance. Use the value obtained by the equation (TJ - TT)/PD where TT is the temperature of the package case determined by a thermocouple.

Electrical Design Considerations
As noted above, the junction-to-case thermal resistances quoted in this data sheet are determined using the first definition. From a practical standpoint, that value is also suitable for determining the junction temperature from a case thermocouple reading in forced convection environments. In natural convection, using the junction-to-case thermal resistance to estimate junction temperature from a thermocouple reading on the case of the package will estimate a junction temperature slightly hotter than actual. Hence, the new thermal metric, Thermal Characterization Parameter, or JT, has been defined to be (TJ - TT)/PD. This value gives a better estimate of the junction temperature in natural convection when using the surface temperature of the package. Remember that surface temperature readings of packages are subject to significant errors caused by inadequate attachment of the sensor to the surface and to errors caused by heat loss to the sensor. The recommended technique is to attach a 40-gauge thermocouple wire and bead to the top center of the package with thermally conductive epoxy.
6.2 Electrical Design Considerations
CAUTION
This device contains protective circuitry to guard against damage due to high static voltage or electrical fields. However, normal precautions are advised 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 voltage level.
Use the following list of considerations to assure correct operation:
* * Provide a low-impedance path from the board power supply to each VDD pin on the controller, and from the board ground to each VSS (GND) pin. The minimum bypass requirement is to place six 0.01-0.1 F capacitors positioned as close as possible to the package supply pins. The recommended bypass configuration is to place one bypass capacitor on each of the ten VDD/VSS pairs, including VDDA/VSSA. Ensure that capacitor leads and associated printed circuit traces that connect to the chip VDD and VSS (GND) pins are less than 0.5 inch per capacitor lead. Use at least a four-layer Printed Circuit Board (PCB) with two inner layers for VDD and GND. Bypass the VDD and GND layers of the PCB with approximately 100 F, preferably with a high-grade capacitor such as a tantalum capacitor. Because the device's output signals have fast rise and fall times, PCB trace lengths should be minimal.

Consider all device loads as well as parasitic capacitance due to PCB traces when calculating capacitance. This is especially critical in systems with higher capacitive loads that could create higher transient currents in the VDD and GND circuits. All inputs must be terminated (i.e., not allowed to float) using CMOS levels. Take special care to minimize noise levels on the VDDA and VSSA pins. When using Wired-OR mode on the SPI or the IRQx pins, the user must provide an external pull-up device. Designs that utilize the TRST pin for JTAG port or Enhance OnCE module functionality (such as development or debugging systems) should allow a means to assert TRST whenever RESET is asserted, as well as a means to assert TRST independently of RESET. Designs that do not require debugging functionality, such as consumer products, should tie these pins together. The internal POR (Power on Reset) will reset the part at power on with reset asserted or pulled high but requires that TRST be asserted at power on.
