Configuration PROMs For FPGAs Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and '8N' denotes the SOIC-8 package. Confirm RoHS compliance status as listed in the official datasheet. Ensure the ordering part number matches the exact capacity and speed grade required for the target FPGA design.

Configuration PROMs For FPGAs Selection Notes

Select this component when designing with Altera FPGAs requiring non-volatile configuration storage. The EPCQ4ASI8N is suitable for applications needing 4 Mbit capacity. Verify that the target FPGA family supports the EPCQ-A series protocol. Consider the 8-SOIC package constraints for PCB layout and thermal management.

Configuration PROMs For FPGAs Part Context

This component belongs to the EPCQ-A series of serial configuration devices manufactured by Altera (now Intel). These devices are specifically engineered to store configuration bitstreams for Altera programmable logic families. The EPCQ4ASI8N represents a mid-density option within this portfolio, balancing storage needs with interface simplicity for embedded systems.

Configuration PROMs For FPGAs Replacement Considerations

Compatible substitutes include other EPCQ series devices with matching or higher capacity, such as EPCQ8 or EPCQ16, provided the pinout and electrical characteristics remain compatible with the existing FPGA configuration interface.
