The AT17N series FPGA Configuration EEPROM (Configurators) provide an easy-touse,cost-effective configuration memory for Field Programmable Gate Arrays. The AT17N series device is packaged in the 8-lead LAP, 8-lead PDIP, 8-lead SOIC, 20-lead SOIC and 44-lead TQFP, see Table 1. The AT17N series Configurators uses a simple serial-access procedure to configure one or more FPGA devices.

The AT17N series configurators can be programmed with industry-standard programmers,Atmel's ATDH2200E Programming Kit or Atmel's ATDH2225 ISP Cable and factory programming.
