Product details
Overview
S25FS128SDSBHV203 from Infineon is a 128 Mbit (16 MB) serial NOR flash memory with SPI Multi-I/O interface, 1.8 V supply, industrial-plus temperature grade (–40°C to +105°C), and 8-pin WSON 6 × 5 mm package. It supports Quad I/O, DDR Quad I/O (80 MBps), 256-byte page programming, hardware ECC, and hybrid/ uniform sector erase options.
For engineers reviewing the S25FS128SDSBHV203 datasheet, S25FS128SDSBHV203 pinout, S25FS128SDSBHV203 application, or S25FS128SDSBHV203 equivalent, key selection criteria include SPI-MIO read bandwidth, AEC-Q100 Grade 2 qualification, OTP security features, and compatibility with S25FL-P/S family footprints in embedded boot code storage.
Technical Context
This device implements Infineon's Eclipse architecture with 65-nm MIRRORBIT™ technology, enabling high-speed, low-voltage operation at 1.7–2.0 V. It supports both SDR and DDR SPI modes, with configurable 24-/32-bit addressing and SFDP/CFI for auto-configuration.
The flash integrates hardware-based single-bit ECC, program/erase suspend-resume, and dual-sector protection schemes - including status register lock bits and password-controlled Advanced Sector Protection (ASP) - for secure firmware storage in safety-critical systems.

Pinout & Package
Package: 8-pin WSON (6 mm × 5 mm, 0.5 mm pitch), Pb-free, moisture sensitivity level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CS# | Chip Select | Active-low enable for SPI command/address/data transfer; must be held low during full transaction |

| 3 - WP# / IO2 | Write Protect / I/O Line 2 | Hardware write lock when pulled low; functions as IO2 in Quad I/O mode |
| 4 - GND | Ground | Signal and power reference plane; requires low-impedance connection to PCB ground plane |
| 5 - VCC | Supply Voltage | 1.7–2.0 V core supply; decoupling capacitor (100 nF) required within 5 mm of pin |
| 6 - SI / IO0 | Serial Input / I/O Line 0 | Command/address input in standard mode; bidirectional in Dual/Quad I/O for reduced pin count |
| 7 - SCK | Serial Clock | Input clock driving all SPI timing; supports up to 133 MHz SDR or 80 MHz DDR operation |
| 8 - RESET# / IO3 | Reset / I/O Line 3 | Hardware reset trigger; serves as IO3 in Quad I/O mode for full four-line data transfer |
Key Features

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 S25FS128SAGBHI200 | Same die, identical pinout and timing, but rated for Industrial (–40°C to +85°C) only | Lacks +105°C operation - unsuitable for under-hood automotive or high-temp industrial enclosures | Select when ambient temperature stays ≤+85°C and cost optimization is prioritized |
| Winbond W25Q128JVSIM | 1.8 V Quad SPI NOR flash, 128 Mbit, but no DDR mode or hardware ECC | No built-in error correction - requires host-side ECC implementation for safety-critical use | Choose for cost-sensitive consumer applications where ECC is not mandated |
Compared with S25FS128SDSBHV203, the Cypress alternative trades temperature range for lower cost, while the Winbond part omits DDR and hardware ECC - making it less suitable for automotive or medical systems requiring guaranteed data integrity and extended thermal operation.

FAQ
Is S25FS128SDSBHV203 pin-compatible with earlier S25FL-S series devices?
Yes - it maintains identical 8-pin WSON 6×5 mm footprint and SPI command set compatibility with S25FL-S devices, including support for legacy Fast Read and Quad I/O commands. No PCB redesign is needed for drop-in replacement in existing layouts.
Does this device support execute-in-place (XIP) operation?
Yes - it supports Continuous Read mode with wrap-around burst, enabling true XIP execution directly from flash memory. This reduces RAM footprint in microcontroller-based systems by eliminating need to copy firmware to RAM before execution.
What is the function of the RESET# / IO3 pin in Quad I/O mode?
In Quad I/O mode, pin 8 functions as IO3 - the fourth bidirectional data line - enabling full 4-line parallel data transfer. RESET# functionality remains available only in standard SPI mode; asserting RESET# during Quad I/O operation halts the interface and resets internal state.
How is the 1024-byte OTP array used in secure boot implementations?
The OTP array stores immutable cryptographic keys, device-specific identifiers, or hash digests used to verify firmware authenticity during boot. Once programmed, its contents cannot be altered - ensuring root-of-trust integrity even if main flash memory is reprogrammed or corrupted.
