256 Mbit NOR Flash with Quad I/O at 133 MHz
The Infineon S25FL256SAGMFIR01 is a 256 Mbit FL-S series NOR Flash memory organized as 32 M x 8 bits, accessed through a SPI Quad I/O interface clocked at 133 MHz. It operates from a 2.7 V to 3.6 V supply and is rated for the -40°C to 85°C industrial temperature range. This part is designed for code-shadowing, execute-in-place (XIP), and firmware storage in embedded systems where fast read throughput and non-volatile retention are required.
133 MHz clock — read throughput for XIP
The 133 MHz SPI clock rate, combined with Quad I/O, delivers a sustained read throughput that supports execute-in-place without the latency of a DRAM shadow copy. The interface is backward-compatible with standard SPI and Dual I/O modes, so it drops into existing SPI bus topologies with a firmware change to enable the quad commands.
The -40°C to 85°C operating range and 2.7 V to 3.6 V supply rail are specified in the datasheet. The 16-SOIC package uses a standard JEDEC footprint.
