Overview

The EPCQ16ASI8N is a 16Mb serial configuration device designed specifically for Altera/Intel FPGAs. It provides non-volatile storage for FPGA bitstreams using a space-efficient 8-pin SOIC package and supports fast read operations including quad-serial modes to minimize system boot times.

Why Choose This Part

This device offers a high-speed quad-input read mode and over 20-year data retention, ensuring long-term reliability for industrial designs. Its low pin count and 2.7V to 3.6V operating range make it easy to integrate into standard FPGA power domains without additional level shifters.

Applications

FPGA Configuration Storage
Holding the configuration bitstream for Intel Cyclone or Arria series FPGAs to enable automatic loading on power-up.
Non-Volatile Data Logging
Utilizing the 16Mb flash memory for system parameters or error logs accessible via SPI or Quad-SPI interfaces.
Microprocessor Boot Code
Serving as a boot ROM for embedded soft processors implemented within the FPGA fabric using the SRunner driver.
