概要
Description
S25FL256LAGNFI013 is a 256‑Mbit serial NOR flash memory from Spansion/Cypress (S25FL256L family). It provides non-volatile storage for firmware and data in embedded systems, accessed over a serial SPI-compatible interface (standard SPI with support for higher-bandwidth dual/quad I/O read in many variants). Key features typically include page programming (often 256-byte pages), sector/block erase (multiple sizes), security/write-protect options, and low‑power modes including deep power-down. It operates from a single supply in the commonly used 2.7–3.6 V range and supports various temperature ranges per package. The suffix “AGNFI013” describes the specific package, temperature range, and lot/revision for this device.
For exact pinout, timing, voltage, endurance, and command set, refer to the S25FL256L datasheet and the ordering information for S25FL256LAGNFI013.
