... Low-power Standby Mode Description The AT17C020 and AT17LV020 (high-density AT17 Series) FPGA Configuration EEPROMs (Configurators) provide an easy-to-use, cost-effective configuration mem- ory for Field Programmable Gate Arrays. The AT17 Series is packaged in the popular 20-pin PLCC. The AT17 Series family uses a simple serial-access procedure to con- figure one or more FPGA devices ...
