Configuration PROMs For FPGAs Procurement Notes

Verify component authenticity through authorized channels as this part is officially discontinued. Confirm that the specific package variant matches the design requirements, noting potential variations in suffixes such as N or I which may indicate different temperature grades or packaging standards. Ensure compatibility with existing FPGA configuration interfaces before procurement.

Configuration PROMs For FPGAs Selection Notes

Select this component when configuring legacy Altera FPGAs requiring non-volatile storage. Verify that the commercial temperature range meets environmental constraints. Consider pinout compatibility with the target FPGA's configuration pins. Evaluate alternative EPC family members if higher density or industrial temperature ranges are required.

Configuration PROMs For FPGAs Part Context

This component belongs to the Enhanced Configuration (EPC) device family manufactured by Altera. These devices serve as external configuration memory for SRAM-based FPGAs, storing the bitstream data loaded during power-up. The EPC4 model represents a specific density tier within this historical product line.
