Product details
Overview
S25FS128SAGNFV100 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 Quad I/O and DDR read modes up to 80 MBps, featuring 65-nm MIRRORBIT™ Eclipse architecture, 100,000 program-erase cycles, and industrial temperature range (–40°C to +85°C). It is used in boot code storage for microcontrollers in industrial control systems requiring fast XIP execution and secure firmware updates.
For engineers reviewing the S25FS128SAGNFV100 datasheet, S25FS128SAGNFV100 pinout, S25FS128SAGNFV100 application, or S25FS128SAGNFV100 equivalent, key selection factors include hybrid sector erase options (4-KB/32-KB/64-KB), integrated ECC, OTP array size (1024 bytes), and compatibility with S25FL-P/S25FL-S families for migration paths.
Technical Context
This device implements a SPI-MIO interface supporting standard SPI clock modes 0/3, dual/quad I/O, and DDR Quad I/O protocols with SFDP and CFI for auto-configuration. Its Eclipse architecture enables burst wrap and continuous XIP read modes alongside program/erase suspend-resume functionality.
The flash uses 65-nm MIRRORBIT™ technology with physical hybrid sector layout: eight 4-KB sectors plus one 32-KB sector at top/bottom, remainder 64-KB; or eight 4-KB plus one 224-KB sector with remainder 256-KB - configurable via status register bits.

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 |
|---|---|---|---|
| S25FS128SAGNFB101 | Same die, WSON 6×5 mm package but with industrial-plus grade (–40°C to +105°C) | Required for extended-temperature industrial drives or outdoor telecom equipment | Select when ambient operating temperature exceeds +85°C but no package change is desired |
| S25FL128SEGNFB101 | Legacy S25FL-S family; lacks DDR mode and has lower max read rate (66 MBps Quad I/O only) | Used where existing board layout and firmware already support S25FL-S command set without DDR dependency | Choose for drop-in replacement in legacy designs where DDR capability is unused |
Compared with S25FS128SAGNFV100, the AGNFB101 variant extends temperature range without altering footprint or timing, while the S25FL128SEGNFB101 trades DDR performance for broader software compatibility in mature platforms.

FAQ
What package type is used for S25FS128SAGNFV100?
S25FS128SAGNFV100 uses the 8-pin WSON 6 × 5 mm (WND008) package with exposed pad, RoHS-compliant and moisture sensitivity level 3. This compact footprint supports high-density PCB layouts in space-constrained applications such as motor control modules and portable diagnostics equipment.
Does this device support Quad SPI mode with continuous read (XIP)?
Yes, S25FS128SAGNFV100 supports continuous read (XIP) in Quad I/O mode, enabling direct code execution from flash without loading into RAM. The device implements burst wrap addressing and supports both standard and DDR Quad I/O protocols, with maximum throughput of 66 MBps (SDR) or 80 MBps (DDR).
How is sector protection implemented on this flash device?
Sector protection is implemented through three mechanisms: status register-based block protection (hardware/software controllable), advanced sector protection (ASP) with password or boot code control per sector, and one-time programmable (OTP) lock bits. These layers allow granular, persistent protection of boot code, calibration data, and firmware partitions against accidental or malicious overwrite.
Is there hardware ECC support, and what level of correction does it provide?
Yes, S25FS128SAGNFV100 includes on-die hardware ECC that performs automatic single-bit error correction during read operations. It generates and checks Hamming codes transparently, eliminating the need for external error-correction logic or software overhead while maintaining full read throughput and data integrity across the full temperature range.
