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-protection
mechanism 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.
Notes: 1. The 8-lead LAP package has the same footprint as the 8-lead SOIC. Since an 8-
lead SOIC package is not available for the AT17LV512/010/002 devices, it is possi-
ble to use an 8-lead LAP package instead.
2. The pinout for the AT17LV65/128/256 devices is not pin-for-pin compatible with the
AT17LV512/010/002 devices.
3. Refer to the AT17Fxxx datasheet, available on the Atmel web site.
