Description
The S25FL256LAGMFI003 is a 256‑Mbit serial NOR flash memory from Cypress/Spansion used to store firmware and data in embedded systems. It uses a SPI‑compatible interface and supports standard SPI, dual I/O, and quad I/O (QIO) read modes for higher throughput. The device is organized for erase/program operations with typical sector and block sizes (e.g., small 4 KB sectors, larger blocks) and a page program size (commonly 256 bytes). Key features include fast/standard read, page programming, sector/block erase, and security features (block protection and security registers), plus low‑power options such as deep power‑down. Addressing can be 3‑ or 4‑byte (in QPI mode) to access the full 32 MB array. It operates in a defined voltage range (variant dependent, typically around 2.7–3.6 V) with appropriate temperature grades. The FI003 suffix indicates a specific fabrication/revision/packaging variant. For exact electrical characteristics, timing, and usage details, consult the official datasheet and product page.
