The AT17C002A and AT17LV002A (high-density AT17A Series) FPGA Configuration EEPROMs (configurators) provide an easy-to-use, cost-effective configuration memory 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 function 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.
