描述 Description

The AT17C65A/128A/256A and AT17LV65A/128A/256A (low-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. 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 a special EEPROM byte. These devices also support a write-protection mechanism within its programming mode.
