AT17C256 General Description


The AT17C65/128/256 and AT17LV65/128/256 (AT17 Series) FPGA Configuration EEPROMS (Configurator) provide an easy-to-use, cost-effective configuration memory for Field Programmable Gate Arrays. The AT17 Series is pack-aged in the 8-pin DIP and the popular 20-pin PLCC and SOIC. The AT17 Series family uses a simple serial-access procedure to configure one or more FPGA devices. The AT17 Series organization supplies enough memory to con-figure one or multiple smaller FPGAs. Using a special feature of the AT17 Series, the user can select the polarity of the reset function by programming a special EEPROM bit.

The AT17 Series can be programmed with industry standard programmers.
