Configuration PROMs For FPGAs Procurement Notes

Verify that the ordering suffix 'S' corresponds to the 20-lead JEDEC SOIC package as specified in the official documentation. Confirm the voltage operating range matches the specific application requirements, noting the distinction between 3.3V and 5.0V specifications. Ensure compatibility with the target FPGA's master serial mode interface before procurement.

Configuration PROMs For FPGAs Selection Notes

Select this component when a 256-kbit capacity is required for FPGA configuration. It is suitable for designs requiring both 3.3V and 5.0V system support. Consider the 20-lead SOIC package for surface mount applications where higher pin counts are needed compared to the 8-lead options. Verify that the target FPGA family is listed in the compatibility section of the datasheet.

Configuration PROMs For FPGAs Part Context

This part belongs to the AT17LV series of FPGA Configuration EEPROMs manufactured by Microchip Technology (formerly Atmel). These devices serve as configurators to store configuration programs for Field Programmable Gate Arrays. The series includes various densities ranging from 65 kbit to 4 Mbit, with the AT17LV256 representing the 256-kbit density option.

Configuration PROMs For FPGAs Replacement Considerations

The AT17LV65 and AT17LV128 are not recommended for new designs and are replaced by the AT17LV256.
