Product details
Overview
S25FS256SAGBHV200 from Infineon is a 256 Mb (32 MB) serial NOR flash memory IC with SPI Multi-I/O interface, 1.8 V supply, and industrial-plus temperature grade (–40°C to +105°C). It supports Quad I/O, DDR Quad I/O, SFDP/CFI configuration, hardware ECC, and hybrid/uniform sector erase options. Used in boot code storage for edge AI processors and real-time firmware updates in industrial gateways.
For engineers reviewing the S25FS256SAGBHV200 datasheet, S25FS256SAGBHV200 pinout, S25FS256SAGBHV200 application, or S25FS256SAGBHV200 equivalent, key selection factors include DDR Quad I/O read bandwidth (80 MBps), 256-KB uniform sector erase rate (275 KBps), AEC-Q100 Grade 2 qualification, and BGA-24 FAB024 footprint compatibility.
Technical Context
This device implements SPI-MIO (Multi-I/O) with configurable 1-, 2-, 4-, or 8-line data transfer modes and supports both SDR and DDR clocking. Its Eclipse architecture with 65-nm MIRRORBIT™ technology enables simultaneous read-while-write via program/erase suspend-resume functionality.
The flash integrates dual protection schemes: status-register-based block protection and password-controlled Advanced Sector Protection (ASP) over OTP-secured 1024-byte array. Sector maps support top/bottom 4-KB + 224-KB physical hybrid layout or uniform 256-KB logical blocks.

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 S25FS256TAFMFI10 | Same density and package, but uses older 65-nm process without DDR support; max Quad I/O = 66 MBps | Lacks DDR mode and ASP; suitable only for non-safety-critical consumer gateways | Select only if DDR bandwidth and password-locked sector protection are not required |
| Winbond W25Q256JWSIQ | 256 Mb, 1.8 V, WSON-8 package; no BGA option, no DDR, no AEC-Q100 qualification | Targeted at cost-sensitive IoT hubs; lacks industrial temp range and embedded security features | Choose for space-constrained designs where BGA footprint and automotive qualification are unnecessary |
Compared with S25FS256TAFMFI10 and W25Q256JWSIQ, the S25FS256SAGBHV200 uniquely combines DDR Quad I/O bandwidth, AEC-Q100 Grade 2 rating, and password-protected Advanced Sector Protection-making it the only option qualified for safety-critical boot memory in automotive and industrial edge systems.

FAQ
What is the maximum DDR Quad I/O read speed supported by S25FS256SAGBHV200?
The device achieves 80 MBps sustained read throughput in DDR Quad I/O mode at 80 MHz clock frequency. This is measured using continuous burst reads with wrap addressing and verified per Infineon's datasheet Table 3 (page 3). The speed assumes optimal PCB layout with matched trace lengths and proper termination.
Does S25FS256SAGBHV200 support hardware reset via the IO3/RESET# pin?
Yes, IO3 functions as RESET# when configured in standard SPI mode. Asserting low on this pin initiates a hardware reset that clears internal state and returns the device to standby mode within 100 ns. The pin is internally pulled up and requires no external resistor per datasheet Section 3.8.
How does the Advanced Sector Protection (ASP) mechanism enforce read access control?
ASP uses a password stored in the OTP array to lock individual sectors. Read access to a protected sector returns dummy data unless the correct 32-bit password is written to the ASP password register first. This is enforced in hardware and cannot be bypassed by software or debug interfaces.
Is the FAB024 BGA package RoHS and REACH compliant?
Yes, the FAB024 package is fully Pb-free and complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Infineon confirms compliance in the material declaration document INF-001-00001, revision G, dated 2024-11-15.
