Overview

The S25FL256SAGNFI001 is a 256Mbit (32MB) non-volatile CMOS NOR Flash memory featuring a high-speed Quad I/O SPI interface capable of up to 133 MHz. It utilizes Infineon's MirrorBit technology to provide high density and reliability for code storage and data logging applications. The device includes an internal hardware error correction code (ECC) engine and supports Double Data Rate (DDR) read operations for high-throughput requirements.

Why Choose This Part

It offers superior performance with a 133 MHz clock and Quad I/O mode, achieving significant throughput for execution-in-place (XiP) applications. The integrated ECC and 100,000 program/erase cycle endurance ensure high data integrity. Flexibility is enhanced by the hybrid sector architecture, providing 4-KB sectors for small parameter storage and 64-KB sectors for efficient bulk code storage.

Applications

Embedded System Boot Code
Stores bootloader and application firmware for microcontrollers and FPGAs using the AutoBoot feature for fast startup.
High-Performance Data Logging
Utilizes 133 MHz clock speeds and Quad SPI throughput to quickly record telemetry or sensor data in industrial environments.
FPGA Configuration Storage
Provides reliable bitstream storage for large FPGAs that require fast configuration cycles upon power-up.

Getting Started

Integrate the device into your hardware design using the 8-WSON footprint and ensure the SPI master supports Quad I/O commands to maximize throughput. Consult the Infineon Low Level Driver (LLD) or standard SPI-NOR flash libraries such as those found in Zephyr RTOS or Linux MTD drivers. Verify signal integrity at 133 MHz by keeping traces short and ensuring proper decoupling near the VCC pins.
