Description
The AT17C65/128/256A and AT17LV65/128/256A (AT17A Series) FPGA Configuration 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 programming a special EEPROM bit.
The AT17A Series is pin compatible with the industry standard configurator, and can be programmed with industry standard programmers.
