Product details
Overview
S25FS128SDSNFM103 from Infineon is a 128 Mbit (16 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/ uniform sector erase options, and integrated hardware ECC for single-bit error correction. It targets boot code storage in industrial microcontroller systems requiring AEC-Q100 Grade 2 qualification (–40°C to +105°C).
For engineers reviewing the S25FS128SDSNFM103 datasheet, S25FS128SDSNFM103 pinout, S25FS128SDSNFM103 application, or S25FS128SDSNFM103 equivalent, key selection criteria include 1.8 V operation, DDR Quad I/O bandwidth, OTP array size, sector protection granularity, and BGA-24 FAB024 package compatibility.
Technical Context
This device implements SPI-MIO (Multi-Input/Output) with support for standard SPI modes 0/3, Dual/Quad I/O, and DDR Quad I/O command sets. It uses Infineon's 65-nm MIRRORBIT™ Eclipse architecture and includes SFDP v1.6 and CFI for auto-configuration.
The flash supports both hybrid sector erase (eight 4-KB + one 32-KB or 224-KB sectors) and uniform 64-KB/256-KB block erase. Erase suspend/resume, program suspend/resume, and automatic ECC are implemented in hardware without host intervention.
Key Specifications

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 S25FL128SAGMFI000 | Same density, 3.0 V supply, SOIC-16 package only; no DDR mode or FAB024 BGA option | Limited to industrial temperature range (–40°C to +85°C); lacks AEC-Q100 qualification | Select only if 3.0 V system rail and through-hole packaging are mandatory |
| Winbond W25Q128JVSIM | 1.8 V operation, QPI mode supported, but no DDR Quad I/O; 100,000-cycle endurance same | Uses standard SOIC-8 or WSON-8 packages; no BGA-24 footprint or ASP security features | Choose when QPI protocol compatibility outweighs DDR bandwidth and advanced sector protection needs |
Compared with S25FS128SDSNFM103, the Cypress part requires voltage translation in 1.8 V systems and lacks automotive qualification, while the Winbond part omits DDR performance and hardware-enforced password protection-both trade off critical features for cost or legacy interface support.

FAQ
What is the function of the IO3/RESET# pin on S25FS128SDSNFM103?
The IO3 pin serves dual functionality: as IO3 in Quad/DDR I/O modes or as asynchronous RESET# input. When used as RESET#, it forces the device into hardware reset state independent of CS# or clock activity. This pin must be pulled high via external resistor unless actively driven low for reset initiation.
Does S25FS128SDSNFM103 support execute-in-place (XIP) operation?
Yes, S25FS128SDSNFM103 supports continuous read mode for XIP execution. The device allows uninterrupted instruction fetches using Fast Read, Dual I/O, Quad I/O, or DDR Quad I/O commands with burst wrap addressing, enabling direct CPU execution from flash without RAM loading.
How is sector protection implemented in S25FS128SDSNFM103?
Sector protection uses three mechanisms: Status Register bits for contiguous range locking, hardware WP# pin for global write inhibit, and Advanced Sector Protection (ASP) for per-sector password-controlled read/write access. ASP is enforced by on-die boot code and does not require host software intervention.
What package variant does S25FS128SDSNFM103 use?
S25FS128SDSNFM103 uses the FAB024 24-ball BGA package (6 mm × 8 mm, 5 × 5 ball array). It is distinct from WSON or SOIC variants and shares footprint compatibility with other Infineon FS-S devices in the same BGA family.
