Product details
Overview
S25FS128SDSNFM100 from Infineon is a 128 Mb (16 MB) serial NOR flash memory with SPI Multi-I/O interface, operating at 1.8 V supply. It supports Quad I/O and DDR Quad I/O read modes up to 80 MBps, features hardware ECC for single-bit error correction, 100,000 program-erase cycles, and 20-year data retention. Used in boot code storage for industrial microcontrollers and FPGA configuration.
For engineers reviewing the S25FS128SDSNFM100 datasheet, S25FS128SDSNFM100 pinout, S25FS128SDSNFM100 application, or S25FS128SDSNFM100 equivalent, key selection criteria include hybrid/uniform sector erase options, OTP array size, AEC-Q100 Grade 2 qualification, SOIC-16 package compatibility, and SFDP/CFI compliance for auto-configuration.
Technical Context
This device implements SPI-MIO (Multi-I/O) protocol supporting standard, dual, quad, and DDR quad read commands with burst wrap and XIP continuous modes. Its Eclipse architecture with 65-nm MIRRORBIT™ technology enables deterministic timing across industrial temperature range (–40°C to +105°C).
The flash integrates configurable protection mechanisms including status register-based block protection, advanced sector protection (ASP) with password-controlled access, and a 1024-byte one-time programmable (OTP) array for secure boot parameters or calibration data.

Pinout & Package
Package: 16-lead SOIC 300 mil (SO3016), Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CS#) | Chip Select | Active-low enable for SPI command/address/data transfer; must be asserted before each instruction cycle |
| 2 (DO/IO1) | Serial Output / I/O Line 1 | Output during standard/dual read; bidirectional in Quad/DDR modes; requires pull-up for open-drain compatibility |
| 3 (WP#/IO2) | Write Protect / I/O Line 2 | Hardware lock for top/bottom sectors when driven low; functions as IO2 in Quad/DDR protocols |
| 4 (VSS) | Ground | Signal reference plane; separate from power ground in mixed-signal layout best practices |

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 S25FL128SAGMFIR00 | Same density, 1.8 V, SOIC-16; lacks DDR Quad I/O mode and ASP password protection | Supports basic Quad I/O but not DDR; limited sector protection granularity | Select when DDR bandwidth and password-secured sectors are not required |
| Winbond W25Q128JVSIM | 1.8 V, SOIC-16; supports Quad I/O only (no DDR); 1.65–2.0 V supply range; no integrated ECC | Requires external error detection logic; lower max clock rate (104 MHz) | Select for cost-sensitive designs where ECC and DDR performance are secondary |
Compared with S25FS128SDSNFM100, the Cypress alternative omits DDR and ASP capabilities, while the Winbond part lacks hardware ECC and DDR support-both trade off reliability and bandwidth for lower unit cost in less demanding applications.

FAQ
What is the maximum clock frequency supported in DDR Quad I/O mode?
The S25FS128SDSNFM100 supports DDR Quad I/O read operations at up to 80 MHz clock frequency, delivering 80 MBps effective bandwidth. This is specified in the AC characteristics section (Table 6.5) of the datasheet and validated across the full Industrial Plus temperature range (–40°C to +105°C).
Does this device require external ECC circuitry?
No. The device includes an integrated hardware ECC engine that automatically corrects single-bit errors during read operations and detects multi-bit errors. No external logic or software intervention is needed, and the feature is always active without configuration.
Can the OTP array be reprogrammed after initial write?
No. The 1024-byte OTP (One-Time Programmable) array is physically fused after programming and cannot be erased or rewritten. It is intended for permanent storage of cryptographic keys, calibration constants, or device-specific identifiers requiring tamper resistance.
Is SOIC-16 pinout compatible with legacy S25FL-A series devices?
Yes. The S25FS128SDSNFM100 maintains footprint and signal compatibility with S25FL-A, S25FL-K, S25FL-P, and S25FL-S families in SOIC-16 packages. Pin assignments, command set subsets, and timing parameters align to enable drop-in replacement in existing designs.
