Description

The AT17C002A and AT17LV002A (high-density AT17A Series) FPGA Configuration

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

ory for programming Altera FLEX devices. The AT17A Series is packaged in the

popular 20-lead PLCC and the 32-lead TQFP. The AT17A Series family uses a simple

serial-access procedure to configure one or more FPGA devices. The AT17A Series

organization 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 func-

tion by programming internal 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. The READY pin is used

to simplify system power-up considerations.

The AT17A Series Configurators can be programmed with industry-standard program-

mers or Atmel’s ATDH2200E Programming Kit.
