Configuration PROMs For FPGAs Procurement Notes

Verify the exact suffix against official documentation, as standard datasheets typically list EPCS4SI8N. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for end-of-life notifications or discontinuance alerts associated with this specific variant to ensure long-term supply viability.

Configuration PROMs For FPGAs Selection Notes

Select this component for designs requiring low-pin-count, non-volatile configuration storage for compatible Altera FPGAs. Ensure the design supports the active serial configuration scheme. Verify that the available 4 Mbit capacity meets the specific FPGA bitstream size requirements. Confirm compatibility with the intended programming hardware such as USB Blaster.

Configuration PROMs For FPGAs Part Context

This part belongs to the Altera EPCS serial configuration device family, which serves as external flash memory for loading FPGA configurations. These devices eliminate the need for reloading configuration data upon every power-up by storing the bitstream in non-volatile memory. The EPCS4 variant specifically offers 4 Mbit capacity suitable for smaller to medium-sized FPGA devices.
