Description

The AT17LV series FPGA Configuration EEPROMs (Configurators) provide an easy-to-use, cost-effective configuration memory for Field Programmable Gate Arrays. The AT17LV series device is packaged in the 8-lead LAP, 8-lead PDIP, 8-lead SOIC, 20-lead PLCC, 20-lead SOIC, 44-lead PLCC and 44-lead TQFP, see Table 1. The AT17LV series Configurators uses a simple serial-access procedure to configure one or more FPGA devices. The user can select the polarity of the reset function by pro-gramming four EEPROM bytes. These devices also support a write-protectionmechanism within its programming mode.

The AT17LV series configurators can be programmed with industry-standard program-mers, Atmel's ATDH2200E Programming Kit or Atmel's ATDH2225 ISP Cable.
