256 Mbit NOR Flash with Quad SPI for code and data storage
The S25FL256SDSMFV010 is a 256 Mbit (32M x 8) NOR Flash memory from Infineon's FL-S series, organized as 32M x 8 bits and accessed through an SPI Quad I/O interface running at up to 80 MHz. The Quad I/O mode reads four bits per clock cycle, delivering a sustained throughput of 40 MB/s without widening the package footprint beyond the standard 6-pin SPI bus — useful for execute-in-place (XIP) boot and high-speed firmware shadowing in systems where pin count is tight.
Operates from 2.7V to 3.6V, which aligns with common 3.3V logic rails used across MCU and SoC platforms.
Infineon lists the S25FL256SDSMFV010 as Active. Sourced per RFQ against your line-item quantity.
16-SOIC package — board-fit and rework considerations
Housed in a 16-SOIC (0.295-inch body width, 7.50 mm) surface-mount package with a 1.27 mm pitch — a common footprint that reflows on standard lead-free profiles and is inspectable without X-ray. The wide body width provides good thermal coupling to the PCB copper pour for heat spreading during erase/write cycles.
