• Manufacturer Part Number: AT17C002
• Description: FPGA Configuration EEPROM Memory
• Manufacturer: ATMEL [ATMEL Corporation]

Example Circuits
Figure 1. AT17 Series Device for Programming PSLI Devices
Notes:
The FPGA CON/DONE output drives the CE input of the AT17 Series Configurator, while the RESET/OE input is driven by
the FPGA INIT pin. This connection works under all normal circumstances, even when the user aborts the configuration
before CON/DONE has gone High. A Low level on the RESET/OE input, during FPGA reset, clears the configurator’s inter-
nal address pointer so that the reconfiguration starts at the beginning.
