S25FL256SAGBHV200

Introduction to S25FL256SAGBHV200
- Type: 256-Mbit serial NOR flash memory from the S25FL256S family (Spansion/Cypress). Non-volatile storage for firmware/data with execute-in-place (XIP) capability.
- Interface: Serial SPI with standard SPI and enhanced Dual/Quad I/O read modes for higher throughput.
- Organization: 256 Mbit (32 MB) with sector/block erase structure and page programming.
- Power/voltage: Operates from 2.7–3.6 V; optimized for low power with deep power-down.
- Features: Write enable/disable control, sector protection/security features, fast read, and power-down options.
- Packaging/temperature: Industrial/extended-temperature variants and multiple package options; the BHV200 suffix denotes a specific package/temperature code—check the datasheet for details.
- Applications: Boot firmware storage, code execution in embedded MCUs, data logging.
- Note: For exact timing, voltage, organization, and package options, consult the S25FL256SAGBHV200 datasheet.
