Product details
Overview
S25FS256SDSBHI200 from Infineon is a 256 Mb (32 MB) serial NOR flash memory IC with SPI Multi-I/O interface, 1.8 V supply, industrial-plus temperature range (–40°C to +105°C), and BGA-24 6 × 8 mm package (FAC024 footprint). It supports Quad I/O, DDR Quad I/O, SFDP/CFI, hardware ECC, and hybrid/uniform sector erase options for embedded boot code and firmware storage.
For engineers reviewing the S25FS256SDSBHI200 datasheet, S25FS256SDSBHI200 pinout, S25FS256SDSBHI200 application, or S25FS256SDSBHI200 equivalent, key selection criteria include 133 MHz fast read speed, 80 MBps DDR Quad I/O throughput, 100,000 program-erase cycles, OTP security, and AEC-Q100 Grade 2 qualification for automotive control modules.
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 compatibility with legacy S25FL-P/S families.
The flash integrates on-die ECC for single-bit correction and supports dual-plane erase suspend/resume, hybrid sector layouts (eight 4-KB + one 224-KB block), and uniform 256-KB sectors. Security includes 1024-byte OTP array, hardware/software block protection, and password-controlled Advanced Sector Protection.

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 S25FS256SDSBHI201 | Same die, identical specs, alternate date code and traceability - not a functional revision | No difference in use case or qualification; intended for supply chain continuity | Select when S25FS256SDSBHI200 is unavailable but same performance and qualification are required |
| Winbond W25Q256JWSIQ | 256 Mb, 1.8 V, SOIC-16 or WSON-8 only; no BGA option; max 104 MHz clock; no DDR mode | Lacks DDR Quad I/O, BGA packaging, and AEC-Q100 Grade 2 - unsuitable for automotive or high-density embedded designs | Consider only for cost-sensitive consumer applications where DDR bandwidth and automotive qualification are not required |
Compared with S25FS256SDSBHI200, the S25FS256SDSBHI201 offers identical functionality with alternate traceability, while the W25Q256JWSIQ sacrifices DDR performance, BGA packaging, and automotive qualification for lower unit cost in non-critical applications.

FAQ
What is the maximum DDR Quad I/O read bandwidth of S25FS256SDSBHI200?
The device achieves 80 MBps DDR Quad I/O read bandwidth at 80 MHz clock frequency, verified per Infineon datasheet Rev. *O Section 3, Performance Summary. This rate assumes optimal PCB layout, proper termination, and host controller support for DDR mode with 4-bit data lanes.
Does S25FS256SDSBHI200 support hardware write protection independent of software commands?
Yes - it provides dual write protection: dedicated WP# pin for hardware-level blocking of program/erase operations, and status register bits for software-configurable sector locking. Both can be used simultaneously for defense-in-depth security in safety-critical firmware storage.
Is the FAC024 BGA package RoHS and REACH compliant?
Yes - all S25FS256SDSBHI200 packages are Pb-free and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed in Infineon's Material Declaration document 002-00368 Rev. *O, page 42.
Can S25FS256SDSBHI200 be used in XIP (eXecute-In-Place) mode?
Yes - it supports Continuous Read mode with wrap burst and QPI interface, enabling direct code execution from flash without copying to RAM. This capability is validated in Section 4.4 of the datasheet and requires host processor support for SPI-MIO continuous read protocols.
