概要

Description

S25FL256SAGMFIG03 is a 256‑Mbit Serial NOR Flash memory from Spansion/Cypress (S25FL256S family). It stores firmware and data and is accessed via a SPI‑compatible interface (standard SPI, with Dual/Quad I/O or QPI modes on supported variants) for high‑speed reads. The device holds 32 MB of flash organized into 4 KB sectors and 64 KB blocks, supports page programming (typically up to 256 bytes per write), and offers fast/read modes, continuous read, and security/write‑protect features. It operates from a supply range of 2.7–3.6 V. The -GMFIG03 suffix indicates packaging/grade options (not functionality); exact pinout, package type, and timing depend on the specific variant and datasheet. Common uses include boot firmware, code storage, and data storage in embedded systems. For precise electrical characteristics, timing, and packaging details, refer to the S25FL256S datasheet and the specific -GMFIG03 datasheet variant.

Features

Here are the main features of S25FL256SAGMFIG03 (256-Mbit serial flash):
- Density: 256-Mbit (32 MB) serial flash memory
- Interface: SPI with Dual I/O, Quad I/O and QPI modes; supports standard, fast, Dual/Quad IO fast reads, and QPI
- Speed: up to 104 MHz clock in SPI/QPI/Quad modes
- Addressing: 24-bit addressing (no 4-byte mode required for this size)
- Organization: 16,777,216 x 8 bits; 256-byte page size
- Erase: 4 KB sectors, 64 KB blocks, and full-chip erase
- Program: Page program up to 256 bytes per operation
- Power: typical operating voltage 2.7–3.6 V
- Power-down: deep power-down mode for low standby current
- Endurance & retention: ~100k program/erase cycles per sector; data retention ~20 years
- Protection: hardware write-protect (BP bits), security registers/OTP options, SFDP for parameter discovery
- Temp range: -40°C to 85°C (industrial/commercial variants)
- Additional: supports suspend/resume of program/erase operations
Note: exact temperature grade and package options may vary by specific lot/revision.

Package

8-pin SOIC (SOP-8) package — i.e., a Small Outline Integrated Circuit package, Pb-free.

Pinout

- Pin count: 8 pins
