Product details
Overview
S25FS256SDSBHV203 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 and uniform sector erase options, and integrated hardware ECC for single-bit error correction. It targets boot code storage in industrial and automotive microcontroller systems requiring high reliability and fast XIP execution.
For engineers reviewing the S25FS256SDSBHV203 datasheet, S25FS256SDSBHV203 pinout, S25FS256SDSBHV203 application, or S25FS256SDSBHV203 equivalent, key selection factors include its 1.7–2.0 V supply range, AEC-Q100 Grade 2 (–40°C to +105°C) qualification, BGA-24 FAB024 package, SFDP/CFI support, and OTP array for secure configuration storage.
Technical Context
This device implements Infineon's Eclipse architecture with 65-nm MIRRORBIT™ technology, enabling simultaneous read-while-write via program/erase suspend-resume functionality. It supports both SDR and DDR SPI modes, with configurable 24-/32-bit addressing and full command compatibility across S25FL-P/S SPI families.
The flash integrates dual protection mechanisms: status register-based block protection and password-controlled Advanced Sector Protection (ASP), plus a 1024-byte one-time programmable (OTP) array for immutable security keys or calibration data.

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 S25FS256SAGBHVF010 | Same die, identical electrical specs and pinout; differs only in date code and traceability marking | No functional difference; fully interchangeable in all designs | Select when requiring Cypress-branded traceability or legacy procurement alignment |
| Winbond W25Q256JWSIQ | 256 Mb, 1.8 V, but lacks DDR mode, ASP, and OTP; max Quad I/O = 40 MBps | Suitable for cost-sensitive non-automotive applications where DDR/XIP not required | Choose only if DDR performance and advanced security features are unnecessary |
Compared with S25FS256SDSBHV203, the Cypress alternative offers identical functionality and qualification, while the Winbond part trades DDR speed and ASP security for lower cost-making it viable only in non-safety-critical, non-XIP use cases.

FAQ
Is S25FS256SDSBHV203 pin-compatible with earlier S25FL-S series devices?
Yes - it maintains identical pinout and command set compatibility with S25FL-P and S25FL-S families, including SOIC, WSON, and BGA packages. The FAB024 BGA footprint matches S25FL256SAGBHVF010, enabling drop-in replacement without PCB redesign.
Does this device support Execute-in-Place (XIP) operation?
Yes - it supports continuous burst read mode and QPI interface, enabling true XIP execution from flash. Combined with DDR Quad I/O at 80 MBps, it delivers sufficient bandwidth for real-time MCU instruction fetch without local RAM caching.
What is the function of the IO3 pin in reset mode?
IO3 serves as RESET# input when configured via status register bit SR3[1]. Asserting low on IO3 initiates hardware reset, clearing internal state and returning to default SPI mode - essential for recovery after brown-out or communication errors in automotive systems.
How is the 1024-byte OTP array used in secure boot implementations?
The OTP array stores immutable values such as public key hashes, root-of-trust certificates, or cryptographic seeds. Once programmed, it cannot be erased or rewritten, ensuring that boot verification logic always references authentic, factory-provisioned security anchors.
