Overview

The S25FL256SAGMFIR03 is a high-performance 256Mbit (32M x 8) non-volatile CMOS NOR Flash memory device utilizing MirrorBit technology. It operates on a 2.7V to 3.6V supply and supports Quad I/O SPI with clock speeds up to 133 MHz for rapid data access. This automotive-grade component includes integrated ECC and advanced sector protection for high-reliability applications.

Why Choose This Part

The device features internal hardware Error Correction Code (ECC) to maintain data integrity over its 100,000 cycle endurance. It offers high-speed performance with a Quad I/O interface capable of 133 MHz, while the AutoBoot feature simplifies system startup by automatically loading the first pages of memory after power-on.

Applications

Automotive ADAS Systems
High-speed code execution and data storage for advanced driver-assistance systems requiring AEC-Q100 reliability.
Industrial Control Units
Robust firmware storage with 20-year data retention and advanced sector protection against unauthorized modification.
Embedded Execution-in-Place (XiP)
