Description

The AT17C65/128/256 and AT17LV65/128/256 (low-density AT17 Series) FPGA Configuration EEPROMs (Configurators) provide an easy-to-use, cost-effective configuration memory for Field Programmable Gate Arrays. The low-density AT17 Series is packaged in the 8-pin PDIP, 8-lead SOIC, and the popular 20-lead 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 configure one or multiple smaller FPGAs. Using a feature of the AT17 Series, the user can select the polarity of the reset function by programming a special EEPROM byte. These devices also support a write-protection mechanism within its programming mode.

The AT17 Series Configurators can be programmed with industry-standard programmers, or Atmel’s ATDH2200E Programming Kit.
