Overview

The S25FL256SAGMFI011 is a 256Mbit (32MB) non-volatile NOR Flash memory IC featuring high-speed SPI and Quad I/O interfaces. Operating at clock frequencies up to 133 MHz, it provides fast data throughput for code execution and data storage in embedded systems. This component is housed in a 16-SOIC package and operates within a voltage range of 2.7V to 3.6V.

Why Choose This Part

The part supports Quad I/O and Double Data Rate (DDR) read modes, reaching up to 104 MHz and 80 MHz respectively, which significantly enhances bandwidth over standard SPI. It offers robust reliability for industrial environments with an operating temperature range of -40C to 85C and low standby power consumption of 70uA. The MirrorBit technology used in the FL-S family provides higher density and faster programming times compared to traditional floating-gate architectures.

Applications

High-Performance Execute-in-Place (XiP)
Utilizes Quad I/O and high clock speeds to allow microcontrollers to execute code directly from external flash with minimal latency.
Industrial Control Systems
Provides reliable non-volatile storage for firmware, configuration tables, and critical system logs in factory automation hardware.
Network Infrastructure
Used in routers and switches to store boot images and complex operating system stacks that require fast loading during power-up.
Advanced Embedded Graphics
Stores large UI assets, fonts, and bitmap images for displays that require high-speed data transfer to maintain frame rates.

Getting Started

To integrate this flash, ensure your MCU's SPI controller supports Quad I/O (QSPI) for maximum performance. Designers should consult the Infineon FL-S datasheet for specific command sets and timing requirements, particularly for the hybrid sector architecture. For hardware evaluation, engineers often use universal programmers or development platforms like the Infineon CY14V101-DVK.
