Product details
Overview
S25FS256SAGBHV203 from Infineon is a 256 Mb (32 MB) serial NOR flash memory with SPI Multi-I/O interface, operating at 1.8 V supply, supporting DDR Quad I/O read up to 80 MBps, hybrid/ uniform sector erase options, and integrated hardware ECC for single-bit error correction. It is used in industrial and automotive boot code storage requiring high reliability and fast XIP-capable reads.
For engineers reviewing the S25FS256SAGBHV203 datasheet, S25FS256SAGBHV203 pinout, S25FS256SAGBHV203 application, or S25FS256SAGBHV203 equivalent, key selection factors include 1.7–2.0 V operation, AEC-Q100 Grade 2 qualification (–40°C to +105°C), BGA-24 FAB024/FAC024 footprint compatibility, SFDP/CFI support, and OTP array security.
Technical Context
This device implements SPI-MIO (Multi-I/O) with configurable 24-/32-bit addressing, supporting standard SPI modes 0/3 and DDR mode. It integrates Eclipse architecture with 65-nm MIRRORBIT™ technology to enable burst wrap, continuous XIP, and QPI read modes.
Its embedded algorithm supports program/erase suspend/resume, automatic ECC generation, and dual-sector protection via status register bits and advanced sector protection (ASP) with password-controlled access to boot sectors and OTP regions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FS256SDSBHVF103 | Same die, identical pinout and timing; differs only in marking and tape/reel packaging | No functional difference; suitable for drop-in replacement where packaging format allows | Select when sourcing from legacy Cypress channel or requiring specific reel orientation |
| Winbond W25Q256JWSIQ | 256 Mb, 1.8 V, but lacks DDR mode, ASP, and AEC-Q100 Grade 2 qualification | Lower-cost option for commercial-grade applications without safety or high-speed XIP needs | Choose only if DDR performance and automotive qualification are not required |
Compared with S25FS256SAGBHV203, the Cypress variant offers identical functionality with packaging variance, while the Winbond part trades DDR speed, ASP security, and automotive qualification for cost-making it unsuitable for safety-critical or high-bandwidth boot use cases.

FAQ
What package type does S25FS256SAGBHV203 use?
S25FS256SAGBHV203 uses a Pb-free BGA-24 package with either 5 × 5 ball (FAB024) or 4 × 6 ball (FAC024) footprint. Both variants measure 6 × 8 mm and are qualified for industrial and automotive applications. The SOIC-16 package is not offered for the 256 Mb density.
Does this device support execute-in-place (XIP) operation?
Yes, S25FS256SAGBHV203 supports continuous XIP mode using Fast, Dual I/O, Quad I/O, and DDR Quad I/O commands. Its burst wrap capability and low-latency read paths enable deterministic instruction fetch directly from flash without copying to RAM.
How is security implemented in this flash device?
Security includes a 1024-byte one-time programmable (OTP) array, hardware block protection via status register bits, and Advanced Sector Protection (ASP) with password-controlled read/write access to individual sectors. ASP can be enabled via boot code or password, and supports lock-down of boot sectors.
Is S25FS256SAGBHV203 compatible with legacy S25FL-S devices?
Yes-S25FS256SAGBHV203 maintains serial command subset and footprint compatibility with S25FL-S devices. It also supports the same SFDP/CFI parameter structures and hybrid/uniform sector maps, enabling migration without PCB redesign or driver changes.
