Description
The AT17LV series FPGA Configuration EEPROMs Configurators provide an easy to-use, cost-effective configuration memory for Field Programmable Gate Arrays. The AT17LV series device is packaged in the 8-lead LAP, 8-lead PDIP, 8-lead SOIC, 20-lead PLCC, 20-lead SOIC and 44-lead TQFP, see Table 1-1. The AT17LV series Configurators uses a simple serial-access procedure to configure one or more FPGA devices. The user can select the polarity of the reset function by programming four EEPROM bytes. These devices also support a write-protection mechanism within its programming mode.
The AT17LV series configurators can be programmed with industry-standard pro grammers, Atmel’s ATDH2200E Programming Kit or Atmel’s ATDH2225 ISP Cable.
