Product details
Overview
S25FL128LAGMFM000 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 supports XIP (execute-in-place) operation in embedded microcontroller boot applications.
For engineers reviewing the S25FL128LAGMFM000 datasheet, S25FL128LAGMFM000 pinout, S25FL128LAGMFM000 application, or S25FL128LAGMFM000 equivalent, key selection criteria include read latency, sector erase granularity, write endurance (100K cycles), data retention (20 years), and industrial temperature range (−40°C to +85°C).
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with enhanced Quad I/O mode for 4-bit-wide data transfers, enabling up to 40 MB/s effective throughput. It features a 64-KB uniform sector architecture with configurable 4-KB subsectors and supports both volatile and non-volatile status register writes.
The memory includes hardware write protection via WP# pin and software-controlled block protection (BP0–BP2 bits), plus a 128-bit unique ID for device authentication. Erase suspend/resume and deep power-down modes are supported for system-level power management.

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 |
|---|---|---|---|
| S25FL128SAGMFM000 | Same density and package, but with 1.8 V core supply (vs 3.3 V); different VCC range and timing specs | Targets ultra-low-power portable medical devices requiring single-supply 1.8 V operation | Select only if system uses 1.8 V I/O and requires lower active current |
| MX25L12833FZC-10G | 128 Mbit, 3.3 V, but supports DTR (double-transfer-rate) mode and has faster 133 MHz clock rating | Preferred for high-throughput boot scenarios where DTR timing margin is available | Choose when higher read bandwidth is critical and PCB layout supports tighter DTR timing constraints |
Compared with S25FL128SAGMFM000 and MX25L12833FZC-10G, the S25FL128LAGMFM000 offers optimal balance of industrial temperature support, proven Quad SPI compatibility with legacy MCU boot ROMs, and robust 3.3 V operation without DTR complexity.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL128LAGMFM000 supports up to 100 MHz in standard Quad SPI read mode. This enables sustained read throughput of approximately 40 MB/s, verified under 3.3 V supply and industrial temperature conditions per Infineon's datasheet DS-S25FL128L-002.
Does this device support execute-in-place (XIP) operation?
Yes, it supports XIP mode via continuous read commands. The device delivers consistent read latency (tCR) of 8 ns at 100 MHz, allowing direct code execution from flash without loading into RAM, reducing system memory footprint.
How many program/erase cycles does this flash guarantee?
Infineon specifies 100,000 program/erase cycles per sector, validated across the full industrial temperature range (−40°C to +85°C). Endurance is measured using standard JEDEC JESD22-A117 methodology.
Is hardware write protection enabled by default?
No. Hardware write protection is controlled by the WP# pin and must be externally pulled low to activate. By default, WP# is inactive (high), allowing full command access unless configured otherwise in the system design.
