Description
The AT17A series FPGA configuration EEPROMs (Configurators) provide an easy-to-
use, cost-effective configuration memory for Field Programmable Gate Arrays. The
AT17A series device is packaged in the 8-lead PDIP
(1)
, 20-lead PLCC and 32-lead
TQFP, see Table 1. The AT17A series configurator uses a simple serial-access proce-
dure to configure one or more FPGA devices. The user can select the polarity of the
reset function by programming four EEPROM bytes.These devices also support a
write-protection mechanism within its programming mode.
Note: 1. The 8-lead LAP, PDIP and SOIC packages for the AT17LV65A/128A/256A do not
have an A label. However, the 8-lead packages are pin compatible with the 8-lead
package of Altera’s EEPROMs, refer to the AT17LV65/128/256/512/010/002/040
datasheet available on the Atmel web site for more information.
The AT17A series configurators can be programmed with industry-standard program-
mers, Atmel’s ATDH2200E Programming Kit or Atmel’s ATDH2225 ISP Cable.
