IFXS25FL256LAGNFB010

Overview

The S25FL256LAGNFB010 is a 256Mbit (32MB) non-volatile NOR Flash memory IC from Infineon Technologies. It operates on a 2.7V to 3.6V supply and supports high-speed data transfer through SPI, Dual I/O, Quad I/O, and QPI interfaces at clock frequencies up to 133 MHz. Built on a 65-nm floating gate process, this memory offers robust data retention and extended temperature support from -40C to 105C.

Why Choose This Part

This component offers significant flexibility with support for both 24-bit and 32-bit addressing and Double Data Rate (DDR) options for maximum throughput. It is footprint-compatible with multiple legacy Cypress and Infineon SPI families, simplifying hardware migration while maintaining low power consumption with a 2 microamp shutdown current.

Applications

Getting Started

Engineers can interface this device with any microcontroller supporting SPI modes 0 or 3. It supports the Serial Flash Discoverable Parameters (SFDP) standard, allowing host firmware to automatically identify memory characteristics and timing requirements. Evaluation is typically performed using universal programmers or by integrating the device into existing development kits with SOIC-8 footprints.
