Product details

32 Mb serial config memory for Altera FPGAs

The Intel / Altera EPCQ32ASI8N is a 32 Mb serial configuration device from the EPCQ-A series, designed to store FPGA bitstreams for Altera FPGAs. It is in-system programmable, allowing firmware updates without removing the part from the board. The 2.7 V supply rail and 8-SOIC package make it a drop-in fit for designs that need a compact, single-chip configuration memory.

32 Mb — what it holds

The 32 Mb frame size stores the configuration bitstream for Altera FPGAs. Check your fitter report to confirm the.pof file fits within this boundary.

In-system programmable — field updates without a socket

The EPCQ32ASI8N supports in-system programming via the JTAG interface on the FPGA. This means you can reprogram the configuration memory after the board is assembled, which simplifies firmware rollouts and rework. No need for a separate programmer or socket — the FPGA handles the write operation through its configuration controller.

Frequently asked questions

Is the EPCQ32ASI8N an exact replacement for the EPCQ32A?

The EPCQ32ASI8N is the 8-SOIC variant of the EPCQ32A family. The base device function and 32 Mb density are the same; verify the package and temperature grade match your existing BOM.

Can the EPCQ32ASI8N be programmed in-circuit?

Yes, the device is in-system programmable. The FPGA writes the configuration bitstream to the EPCQ32ASI8N via the JTAG interface during board-level programming.

What is the EPCQ32ASI8N used for?

It is a serial configuration memory for Altera FPGAs, storing the bitstream that defines the FPGA logic. Typical applications include industrial control, communications infrastructure, and any design using a mid-density Altera FPGA.
