Product details
Overview
S25FS128SAGNFM103 from Infineon is a 128 Mb (16 MB) serial NOR flash memory with SPI Multi-I/O interface, 1.8 V supply, industrial temperature grade (–40°C to +85°C), and WSON 6 × 5 mm package. It supports Quad I/O read up to 66 MBps, DDR Quad I/O at 80 MBps, 100,000 program-erase cycles, 20-year data retention, and hardware ECC for single-bit error correction.
For engineers reviewing the S25FS128SAGNFM103 datasheet, S25FS128SAGNFM103 pinout, S25FS128SAGNFM103 application, or S25FS128SAGNFM103 equivalent, key selection criteria include hybrid/uniform sector erase options, SFDP/CFI configuration support, OTP array size (1024 bytes), block protection granularity, and AEC-Q100 grade compatibility for automotive boot code storage.
Technical Context
This device implements Infineon's 65-nm MIRRORBIT™ Eclipse architecture with SPI-MIO (Multi-I/O) protocol supporting standard SPI modes 0/3, Dual/Quad I/O, DDR Quad I/O, and QPI mode. It uses extended addressing (24-/32-bit) and provides configurable hybrid sector layout: eight 4-KB + one 32-KB sectors plus uniform 64-KB blocks.
Internal hardware ECC performs real-time single-bit correction during read operations; program/erase suspend-resume enables concurrent background operations; and SFDP v1.6/JEDEC JESD216 compliance allows automatic configuration by host controllers without hard-coded parameters.

IC Role / Device Role / Timing Role: Industrial-grade flash with –40°C to +85°C operation and deep power-down current (6 µA) minimizing battery drain during grid outages. Use Value: Uniform 64-KB erase blocks simplify firmware update partitioning and reduce risk of partial writes during brown-out conditions. |
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 S25FL128SAGNFI101 | Same die, legacy Cypress branding; identical electrical specs, pinout, and timing; no functional difference | No change in design-in requirements; fully drop-in compatible with same PCB layout and firmware | Select when sourcing from legacy inventory or distributor stock labeled under Cypress brand |
| Winbond W25Q128JVSIM | 1.8 V Quad SPI NOR; lacks DDR mode, SFDP v1.6, and hardware ECC; 64-KB uniform sectors only | Suitable for cost-sensitive designs where DDR bandwidth and ECC are not required | Choose only if application does not require DDR read performance or on-the-fly error correction |
Compared with S25FS128SAGNFM103, the Cypress alternative offers identical functionality under rebranded packaging, while the Winbond part trades DDR capability and ECC for lower cost-making it viable only in non-safety-critical, bandwidth-tolerant applications.

FAQ
Is S25FS128SAGNFM103 pin-compatible with S25FL-S series devices?
Yes, it is footprint-compatible with S25FL-P and S25FL-S families per Infineon's migration notes. The WSON 6×5 mm package matches S25FL128SAGNFI101 pin-for-pin, including identical signal assignments and thermal pad configuration. No PCB redesign is needed for migration from legacy Cypress S25FL-S parts.
Does this device support execute-in-place (XIP) operation?
Yes, it supports continuous read mode for XIP execution. The device delivers burst-wrap reads with wrap-around addressing and zero-latency command execution, enabling direct CPU instruction fetch from flash without intermediate RAM buffering. This is validated across all supported read commands including Fast, Dual I/O, and Quad I/O modes.
What is the function of the RESET# / IO3 pin in normal operation?
In standard SPI mode, RESET# is an active-low hardware reset that forces the device into a known initial state, clearing internal registers and aborting ongoing operations. During Quad I/O mode, it becomes IO3 - the fourth bidirectional data lane - and must be driven by the host controller for full-width transfers; floating this pin in Quad mode causes communication failure.
How is the 1024-byte OTP array accessed and protected?
The OTP array is accessed via dedicated JEDEC-standard One-Time Program commands (0x4B, 0x42). Once programmed, bits cannot be erased; write protection is enforced by status register bits and optional password lock via Advanced Sector Protection. Access requires issuing an unlock sequence before programming, and read access may be password-gated independently of write control.
