Product details

128 Mbit NOR flash, SPI bus, 104 MHz — what it is

The S25FL128P0XNFI001M is a 128 Mbit NOR flash from Infineon's FL-P series, organised as 16M x 8 bits and accessed over a standard SPI bus at up to 104 MHz.

SPI clock and write-cycle timing — what they mean for firmware updates

The 104 MHz SPI clock delivers a read throughput of roughly 104 Mbit/s in single-I/O mode — enough to shadow code into SRAM or execute-in-place for moderate-speed microcontrollers without stalling the core. Page write time is 3 ms typical — for a 256-byte page, that translates to about 12 µs per byte. Firmware-update routines should budget for the cumulative write latency across the full 128 Mbit array; a full-chip erase followed by page writes can take tens of seconds.

Package and reflow — MSL and pad design

Check the moisture-sensitivity level before the reflow oven — if it is MSL 3 or higher and the part has been out of the dry pack longer than the floor-life rating, bake it or it popcorns.

Frequently asked questions

What is the replacement for S25FL128P0XNFI001M?

No official replacement is recorded in the lifecycle entry. The S25FL128P0XNFI003M variant shares the same base product number (S25FL128) and may be pin-compatible, but the buyer must verify the suffix differences — package, temperature range, or other parametric deltas — before substituting.

What is the difference between S25FL128P0XNFI001M and S25FL128P0XNFI003M?

Both share the same 128 Mbit NOR flash core, SPI interface, and 104 MHz clock. The suffix difference (001M vs 003M) typically indicates a packaging or temperature-grade variant — the 001M ships in tray, the 003M may be tape-and-reel. Confirm the exact package code and operating temperature range from the respective datasheets before cross-referencing.
