IFXS25FL256S 256 Mbit SPI NOR Flash

Overview

S25FL256SAGBHIA13 is an Infineon serial NOR flash memory device for storing firmware, configuration data, and other nonvolatile code or assets. It uses a standard SPI interface, making it easy to connect to MCUs, application processors, and embedded Linux systems. The 256 Mbit density is a practical fit for designs that need more storage than small onboard flash can provide.

Why Choose This Part

This part combines a widely supported SPI interface with a relatively large NOR flash capacity, which makes board integration straightforward. Serial NOR flash is a good choice when you need random read access, reliable nonvolatile storage, and simple MCU or SoC connectivity. It is especially useful when internal flash is too small or when you want to separate application storage from the main processor.

Applications

Getting Started

Connect the flash to a host MCU or processor using SPI signals such as clock, chip select, MOSI, and MISO, plus the required power and ground pins. Most embedded toolchains can use standard SPI flash drivers, and many MCUs already have example code or BSP support for external NOR flash. Before finalizing the design, verify the exact package, voltage range, timing, and any erase/program command requirements in the Infineon datasheet and reference software.
