The AT17A series FPGA configuration EEPROMs (Configurators) provide an easy-to-use, cost-effective configuration memory for Field Programmable Gate Arrays. TheAT17A series device is packaged in the 8-lead PDIP(1), 20-lead PLCC and 32-leadTQFP, see Table 1. The AT17A series configurator uses a simple serial-access proce-dure to configure one or more FPGA devices. The user can select the polarity of thereset function by programming four EEPROM bytes.These devices also support awrite-protection mechanism within its programming mode.
