概要

Description

S25FL256SAGBHIA10 is a 256‑Mbit serial NOR flash memory from Cypress/Spansion (S25FL family). It provides firmware/data storage for embedded systems with a low‑pin SPI interface.
Key points:
- Capacity: 256 Mbit (32 MB) of nonvolatile storage.
- Interface: SPI-compatible serial interface with support for standard SPI and dual/quad I/O modes for higher throughput; suitable for code storage and execution in place (XIP).
- Voltage/temperature: typically 2.7–3.6 V operation; industrial temperature range (−40°C to 85°C) variants are available.
- Operations: supports page programming and sector/block erasing, plus security features (protectable regions/OTP) and various read modes.
- Applications: boot flash, firmware storage, data logging in consumer, industrial, and automotive electronics.
- Packaging: RoHS-compliant options; exact package type and lead count vary by variant (IA10/other suffixes).
Note: For precise timings, electrical characteristics, and packaging, consult the latest datasheet for S25FL256SAGBHIA10.

Features

Key features of S25FL256SAGBHIA10 (256 Mbit Serial NOR Flash):

- XIP and commands: execute-in-place support; standard JEDEC command set with RDID, RDSR, RESET, etc.
- Endurance/retention: typical erase cycle endurance (e.g., ~100k cycles per sector) with long data retention
Note: exact frequency and some parameter ranges are mode-dependent; consult datasheet for precise figures.

Package

An 8-pin SOP (SOIC) package (SOP-8).

Pinout

Pin count: 8 pins.
Function: S25FL256SAGBHIA10 is a 256-Mbit Serial NOR Flash memory with an SPI interface. Pin functions (typical 8-pin package):
- CS# – Chip Select
