Product details
Overview
S25FS128SAGBHI303 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 × 8 mm package. It supports Quad I/O, DDR Quad I/O read up to 80 MBps, 256/512-byte page programming, hardware ECC, and hybrid/uniform sector erase options. Used in boot code storage for industrial microcontrollers and FPGA configuration.
For engineers reviewing the S25FS128SAGBHI303 datasheet, S25FS128SAGBHI303 pinout, S25FS128SAGBHI303 application, or S25FS128SAGBHI303 equivalent, this page delivers verified electrical specs, validated pin functions, confirmed industrial-grade timing behavior, and real-world use cases in embedded boot and firmware storage systems.
Technical Context
This device implements SPI-MIO (Multi-Input/Output) protocol supporting standard SPI modes 0/3, Dual/Quad I/O, and DDR Quad I/O with configurable 24-/32-bit addressing. It integrates SFDP v1.6 and CFI for automatic configuration discovery and interoperability with host boot ROMs.
The Eclipse architecture with 65-nm MIRRORBIT™ technology enables 100,000 program-erase cycles and 20-year data retention. Erase flexibility includes hybrid sectors (eight 4-KB + one 32-KB or 224-KB at top/bottom) and uniform 64-KB/256-KB blocks.

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 die, identical pinout and command set; differs only in marking and packaging traceability | No functional difference; qualified for same industrial and automotive grades | Select when requiring Cypress-branded documentation or legacy supply chain alignment |
| Winbond W25Q128JVSIM | 1.8 V operation, but lacks DDR Quad I/O, SFDP v1.6, and ASP; max read rate 40 MBps (Quad I/O) | Suitable for cost-sensitive designs without XIP or advanced security needs | Choose only if DDR performance and per-sector password protection are not required |
Compared with S25FL128SAGMFI000, this part offers identical functionality with Infineon branding and updated lifecycle support; versus W25Q128JVSIM, it delivers 2× read bandwidth, hardware ECC, and robust sector-level security-critical for safety-aware embedded systems.

FAQ
Is S25FS128SAGBHI303 pin-compatible with S25FL-A or S25FL-K series devices?
Yes, it is footprint- and command-compatible with S25FL-A, S25FL-K, S25FL-P, and S25FL-S families. The WNH008 package matches pin assignments for VCC, GND, SCK, CS#, IO0–IO3, and WP#/HOLD#. No PCB redesign is needed for migration from earlier Cypress/Spansion SPI flash devices.
Does this device support execute-in-place (XIP) operation?
Yes, it supports continuous burst read mode with wrap addressing, enabling XIP execution directly from flash memory. Host processors with SPI memory-mapped peripherals (e.g., NXP i.MX RT, Microchip SAM E70) can fetch instructions without copying to RAM, reducing boot latency and SRAM usage.
What is the function of the HOLD# pin during active read operations?
HOLD# suspends ongoing serial transfers without resetting internal state. When asserted during a read, it pauses data output after the current byte; deassertion resumes transmission from the next address. This allows time-critical interrupts to be serviced while preserving flash access context.
Can the OTP array be programmed multiple times?
No-the 1024-byte OTP array is one-time programmable. Each bit can be written from '1' to '0' only once. It is commonly used to store immutable keys, device IDs, or calibration constants that must survive firmware updates and field reprogramming.
