Description

The AT17C512/010A and AT17LV512/010A (AT17A Series) FPGA Configuration EEPROMs (Configurators) provide and easy-to-use, cost-effective configuration memory for programming Altera FLEX Field Programmable Gate Arrays, FPGA, (the "devices"). The AT17A Series is packaged in the popular 20-pin PLCC package. 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 special feature of the AT17A Series, the user can select the polarity of the reset function by programming an EEPROM byte. The AT17C/LV512/010A parts generate their own internal clock and can be used as a system"master" for loading the FPGA devices.

The Atmel devices also supports 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 device memory during in-system programming.

The AT17A Series can be programmed with industry standard programmers.
