Description

The AT17C020 and AT17LV020 (high-density AT17 Series) FPGA Configuration

EEPROMs (Configurators) provide an easy-to-use, cost-effective configuration mem-

ory for Field Programmable Gate Arrays. The AT17 Series is packaged in the popular

20-pin PLCC. The AT17 Series family uses a simple serial-access procedure to con-

figure one or more FPGA devices. The AT17 Series organization supplies enough

memory to configure one or multiple smaller FPGAs. The user can select the polarity

of the reset function by programming internal EEPROM bytes. These devices also

support a system-friendly READY pin, which signifies a “good” power level to the

FPGA and can be used to ensure reliable system power-up.

AT17LV020

The AT17 Series Configurators can be programmed with industry-standard program-

mers or Atmel’s ATDH2200E Programming System.
