Features
Description
The AT17C512A/010A and AT17LV512A/010A (high-density AT17A Series) FPGA
Configuration EEPROMs (Configurators) provide an easy-to-use, cost-effective con-
figuration memory for programming Altera FLEX
packaged in the popular 20-pin PLCC. The AT17A Series family uses a simple serial-
access procedure to configure one or more FPGA devices. The AT17A Series organi-
zation supplies enough memory to configure one or multiple smaller FPGAs. Using a
feature of the AT17A Series, the user can select the polarity of the reset function by
programming four EEPROM bytes. The AT17A parts generate their own internal clock
and can be used as a system “master” for loading the FPGA devices.
The Atmel devices also support a system-friendly READY pin and a write protect
mechanism. The READY pin is used to simplify system power-up considerations. The
WP1 pin is used to protect part of the Configurator memory during in-system
programming.
The AT17A Series Configurators can be programmed with industry-standard program-
mers, or Atmel’s ATDH2200E Programming Kit.
