Product details
Overview
S25FL128LAGMFI010 from Infineon Technologies 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 storage in microcontroller-based systems.
For engineers reviewing the S25FL128LAGMFI010 datasheet, S25FL128LAGMFI010 pinout, S25FL128LAGMFI010 application, or S25FL128LAGMFI010 equivalent, key selection criteria include read latency, sector erase granularity, write protection flexibility, and SPI command compatibility with host MCU firmware stacks.
Technical Context
This device implements a 4-wire SPI bus with support for single/dual/quad I/O modes and uses a 64-Mbit × 2 stacked-die architecture to achieve 128 Mbit density. It features a 256-byte page buffer for fast program operations and includes a 128-bit unique ID register for device authentication.
The memory array is organized into 256 uniform sectors of 64 KB each, with hardware and software write protection via status register bits and block protection registers. Erase suspend/resume functionality enables concurrent background operations during active system execution.

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 supports octal DTR interface (up to 400 MHz) and has enhanced security features including secure OTP area | Required for designs needing higher bandwidth or cryptographic key storage beyond basic UID | Select when migrating to next-gen MCU platforms with octal SPI controllers or requiring secure boot chain extension |
| MX25L12833FZNI-10G | 128 Mbit density, 3.3 V, but uses different command set (no QPI mode) and lacks erase suspend/resume functionality | Suitable only where host firmware does not require background erase concurrency or quad I/O optimization | Choose only if existing driver stack is locked to Macronix command set and no performance uplift is needed |
Compared with S25FL128SAGMFI001, this part trades octal bandwidth and advanced security for lower cost and proven compatibility with legacy SPI controllers; versus MX25L12833FZNI-10G, it delivers superior real-time operation support via erase suspend and faster quad-mode throughput.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL128LAGMFI010 supports up to 100 MHz in Quad SPI mode, delivering 400 MB/s effective throughput. This frequency is guaranteed across the full industrial temperature range and requires proper PCB layout with matched trace lengths and controlled impedance for all four data lines.
Does this part support execute-in-place (XIP) operation?
Yes, the device supports XIP operation via its continuous read mode with wrap-around addressing. The 8 ns read latency and fast access time enable direct code execution from flash without copying to RAM, reducing system memory footprint in cost-sensitive MCU designs.
How many program/erase cycles is this flash rated for?
Infineon specifies 100,000 program/erase cycles per sector, with data retention guaranteed for 20 years at 85°C. This endurance rating applies uniformly across all 256 sectors and is validated under JEDEC JESD22-A117 stress conditions.
Is there hardware support for sector-level write protection?
Yes, hardware write protection is implemented via the WP# pin, which locks all sectors when asserted low. Combined with software-controlled status register bits, this provides dual-layer protection against unintended writes during power transitions or firmware faults.
