Description
The AT17C512/010 and AT17LV512/010 (high-density AT17 Series) FPGA
Configuration EEPROMs (Configurators) provide an easy-to-use, cost-effective configuration memory for programming Field Programmable Gate Arrays. The AT17
Series is packaged in the 8-lead LAP, 8-lead PDIP and the popular 20-lead PLCC. The
AT17 Series uses a simple serial-access procedure to configure one or more FPGA
devices. The user can select the polarity of the reset function by programming four
EEPROM bytes. These devices support a write protection mode and a system-friendly
READY pin, which signifies a “good” power level to the FPGA and can be used to
ensure reliable system power-up.
The AT17 Series Configurators can be programmed with industry-standard programmers, Atmel’s ATDH2200E Programming Kit or Atmel’s ATDH2225 ISP Cable.
