Description

The AT17C65/128/256A and AT17LV65/128/256A (AT17A Series) FPGA Configura-

tion EEPROMS (Configurator) provide an easy-to-use, cost-effective configuration

memory for Field Programmable Gate Arrays. The AT17A Series is packaged in the

popular 20-pin PLCC. The AT17A Series family uses a simple serial-access provides

to configure one or more FPGA devices. The AT17A Series organization supplies

enough memory to configure one or multiple smaller FPGAs. Using a special feature

of the AT17A Series, the user can select the polarity of the reset function by program-

ming a special EEPROM bit.
