Device Description
The control signals for the configuration EEPROM (CE, RESET/OE and CCLK) interface directly with the FPGA device control signals. All FPGA devices can control the entire configuration process and retrieve data from the configuration EEPROM without requiring an external intelligent controller. The configuration EEPROM RESET/OE and CE pins control the tri-state buffer on the DATA output pin and enable the address counter. When RESET/OE is driven High, the configuration EEPROM resets its address counter and tri-states its DATA pin. The CE pin also controls the output of the AT17N series configurator. If CE is held High after the RESET/OE reset pulse, the counter is disabled and the DATA output pin is tri-stated. When OE is subsequently driven Low, the counter and the DATA output pin are enabled. When RESET/OE is driven High again, the address counter is reset and the DATA output pin is tri-stated, regardless of the state of CE. Upon power-up, the address counter is automatically reset.

DATA CLK RESET/OE
Three-state DATA output for configuration. Open-collector bi-directional pin for programming. Clock input. Used to increment the internal address and bit counter for reading and programming. Output Enable (active High) and RESET (active Low) when SER_EN is High. A Low level on RESET/OE resets both the address and bit counters. A High level (with CE Low) enables the data output driver. The logic polarity of this input is programmable as either RESET/OE or RESET/OE. For most applications, RESET should be programmed active Low. This document describes the pin as RESET/OE. Chip Enable input (active Low). A Low level (with OE High) allows CLK to increment the address counter and enables the data output driver. A High level on CE disables both the address and bit counters and forces the device into a low-power standby mode. Note that this pin will not enable/disable the device in the Two-Wire Serial Programming mode (SER_EN Low). Ground pin. A 0.2 F decoupling capacitor between VCC and GND is recommended. Serial enable must be held High during FPGA loading operations. Bringing SER_EN Low enables the Two-Wire Serial Programming Mode. For non-ISP applications, SER_EN should be tied to VCC. 3.3V (10%) Commercial and Industrial power supply pin. NC pins are No Connect pins, which are not internally bonded out to the die. DC pins are No Connect pins internally connected to the die. It is not recommended to connect these pins to any external signal.

FPGA Master Serial Mode Summary
The I/O and logic functions of any SRAM-based FPGA are established by a configuration program. The program is loaded either automatically upon power-up, or on command, depending on the state of the FPGA mode pins. In Master mode, the FPGA automatically loads the configuration program from an external memory. The AT17N Serial Configuration EEPROM has been designed for compatibility with the Master Serial mode. This document discusses the master serial mode configuration of Atmel AT17N series configuration memories, pin compatible with Spartan-II, Spartan-IIE and Spartan XL OTP PROMs.
Control of Configuration
Most connections between the FPGA device and the AT17N Serial EEPROM are simple and self-explanatory. * * * * The DATA output of the AT17N series configurator drives DIN of the FPGA devices. The master FPGA CCLK output drives the CLK input of the AT17N series configurator. SER_EN must be connected to VCC (except during ISP). The CE and OE/Reset are driven by the FPGA to enable output data buffer of the EEPROM.
Programming Mode
The programming mode is entered by bringing SER_EN Low. In this mode the chip can be programmed by the Two-Wire serial bus. The programming is done at VCC supply only. Programming super voltages are generated inside the chip. The AT17N series configurators enter a low-power standby mode whenever CE is asserted High. In this mode, the AT17N256 configurator consumes less than 50 A of current at 3.3V (100 A for the AT17N512/010 and 200 A for the AT17N002/040).
