Product details
Overview
S25FL128LAGMFI003 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0–3.6 V supply voltage, 100 MHz clock frequency, and uniform 256-byte programming page size. It operates in industrial temperature range (−40°C to +85°C) and supports standard, dual, and quad I/O protocols for embedded boot code and firmware storage in microcontroller-based systems.
For engineers reviewing the S25FL128LAGMFI003 datasheet, S25FL128LAGMFI003 pinout, S25FL128LAGMFI003 application, or S25FL128LAGMFI003 equivalent, key selection criteria include sector erase granularity, write protection flexibility, reset recovery time, and SPI command compatibility with legacy and enhanced controllers.
Technical Context
This device implements a 4-wire SPI bus with support for single/dual/quad I/O modes, enabling up to 40 MB/s read throughput in quad mode. It features a 64-KB uniform sector architecture with 256-byte programmable pages and hardware-controlled write protection via WP# pin and status register bits.
The memory includes a 128-bit unique ID, volatile/non-volatile configuration registers, and supports both power-on reset and software reset commands. Erase suspend/resume and deep power-down modes are implemented for system-level power management during firmware updates.

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 |
|---|---|---|---|
| S25FL128SAGMFI001 | Same density and package, but uses newer 65 nm process; lower active current (18 mA vs 25 mA) and faster program time (0.8 ms/page vs 1.2 ms/page) | Preferred for battery-powered edge nodes where power efficiency and update speed are critical | Select when optimizing for energy-per-byte in frequent OTA updates |
| MX25L12833FZNI-10G | Different manufacturer (Macronix); identical pinout and command set, but lacks 128-bit UID and has slower erase time (4 s/sector vs 2.5 s) | Suitable for cost-sensitive industrial controls where unique ID and fastest erase are non-essential | Choose for second-source assurance where full feature parity is not required |
Compared with S25FL128SAGMFI001, this part trades higher active power for broader legacy compatibility; versus MX25L12833FZNI-10G, it adds UID and faster erase at modest cost premium-ideal for traceable firmware deployments.

FAQ
Is S25FL128LAGMFI003 pin-compatible with earlier S25FL128L variants?
Yes, it maintains identical 8-pin SOIC (208-mil) footprint and pin function mapping with S25FL128LxxxFI0xx parts. No PCB redesign is needed when migrating from prior revisions within the same density and voltage grade.
Does this device support XIP (execute-in-place) operation?
Yes, it supports true XIP mode via quad SPI with configurable latency cycles. The device can execute code directly from flash without copying to RAM, reducing boot latency and SRAM usage in MCU-based systems.
What write protection mechanisms are implemented?
It provides three-tiered protection: hardware WP# pin for sector-level lock, non-volatile status register bits (SRWD, BP0–BP3) for permanent or temporary sector locking, and volatile register bits for runtime-only protection during firmware updates.
How is the 128-bit unique ID accessed?
The unique ID is read via the 4BH Read Unique ID command (0x4B) followed by a 4-byte address. It is factory-programmed, unalterable, and used for device authentication, secure boot binding, and firmware version tracking in certified systems.
