Product details

What this NOR Flash delivers for your memory budget

Infineon S25FL128SAGMFN003 is a 128 Mbit NOR Flash from the FL-S series, organised as 16M x 8 bits, with a SPI Quad I/O interface that reads at 133 MHz — enough to support execute-in-place (XIP) boot on a Cortex-M or similar MCU without a parallel bus.

The 125°C ceiling is the junction temperature; derate the clock frequency above 105°C ambient per the datasheet's operating-condition table if you push the full 133 MHz.

Listed as Active with no announced last-time-buy or end-of-life notice from Infineon.

Frequently asked questions

Can S25FL128SAGMFN003 be used with STM32?

Yes. The 128 Mbit density provides 16 MB of code/data storage for firmware images or data logging.

What is the closest pin-compatible alternative to S25FL128SAGMFN003?

For the full -40°C to 125°C range, the S25FL128SAGMFN003 is the correct order code.
