Product details
Overview
S25FS256SAGMFM000 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 temperature grade (–40°C to +85°C). It supports Quad I/O, DDR Quad I/O, SFDP/CFI configuration, hardware ECC, and hybrid/uniform sector erase options for embedded boot and code storage applications.
For engineers reviewing the S25FS256SAGMFM000 datasheet, S25FS256SAGMFM000 pinout, S25FS256SAGMFM000 application, or S25FS256SAGMFM000 equivalent, key selection factors include 133 MHz Fast Read speed (66 MBps), 256/512-byte page programming, 100,000 program-erase cycles, AEC-Q100 Grade 3 qualification, and BGA-24 (FAB024/FAC024) package compatibility.
Technical Context
This device implements Infineon's Eclipse architecture with 65-nm MIRRORBIT™ technology, enabling high-density, low-voltage operation at 1.7–2.0 V. It supports both SDR and DDR SPI modes, with configurable 24-/32-bit addressing and full command subset compatibility across S25FL-P/S25FL-S families.
The flash integrates dual-sector erase architectures-hybrid (eight 4-KB + one 32-KB or 224-KB sectors) and uniform (64-KB or 256-KB blocks)-and includes dedicated OTP (1024 bytes), block protection via status register, and password-enabled Advanced Sector Protection for secure firmware storage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FS256SAGNFM000 | Same die, identical electrical specs, but WSON-8 (6×5 mm) package - no BGA footprint | Limited to space-constrained PCBs without BGA routing capability | Select when board area is critical and BGA assembly is unavailable |
| Infineon S25FS256SAGMFM001 | Identical functionality and package, but Automotive AEC-Q100 Grade 2 (–40°C to +105°C) | Required for under-hood automotive modules exceeding +85°C ambient | Select when extended temperature operation is mandated by system thermal profile |
Compared with S25FS256SAGNFM000 and S25FS256SAGMFM001, the S25FS256SAGMFM000 provides optimal cost/performance balance for industrial-grade applications where BGA packaging and +85°C operation are sufficient - avoiding over-specification while maintaining full feature parity.

FAQ
Is S25FS256SAGMFM000 pin-compatible with earlier S25FL-S series devices?
Yes - it maintains identical pinout, command set, and footprint compatibility with S25FL-P and S25FL-S families. The SOIC-16 and BGA-24 packages retain the same signal assignments and timing envelopes, enabling drop-in replacement in existing designs without layout changes.
Does this device support Execute-in-Place (XIP) operation?
Yes - the S25FS256SAGMFM000 supports Continuous Read mode with wrap burst, enabling true XIP execution from flash on compatible microcontrollers. This eliminates need for RAM copy during boot, reducing startup time and memory footprint in Cortex-M and RISC-V systems.
What is the function of the IO2 and IO3 pins beyond data I/O?
IO2 serves as Write Protect (WP#) for hardware-based sector locking; IO3 doubles as RESET# for synchronous device reset. Both functions are enabled via status register configuration and operate independently of data transfer, allowing concurrent protection and recovery control.
How is the 1024-byte OTP array used in practice?
The OTP array stores immutable data such as cryptographic keys, device serial numbers, or calibration constants. Once programmed, bits cannot be erased - making it suitable for root-of-trust elements in secure boot chains and regulatory-compliant medical or industrial devices.
