Product details

128 Mbit NOR Flash with Quad-SPI — what it brings to the board

For a BOM line that still calls out this exact order code, procurement will need to source from independent distribution — new-old-stock or qualified surplus inventory. The 16-SOIC footprint and Quad-SPI interface mean a form-fit-function replacement would need to match the 7.50 mm body width and the same command set; the S25FL128P family is a common cross-shop candidate, but verify sector erase granularity and status register layout before committing a board spin.

Write-cycle timing and page program

Page program time is 3 ms typical, and word program time is 5 µs typical. For a 128 Mbit device, bulk erase or sector erase times are not listed here, but the page program figure sets the floor for firmware-update throughput: a 256-byte page at 3 ms means roughly 130 KB/s sustained write speed, adequate for infrequent OTA updates but not for streaming data logging.

Frequently asked questions

Is S25FL129P0XMFI013 obsolete?

Yes, the S25FL129P0XMFI013 is listed as Obsolete. Cypress (Infineon) no longer manufactures it.

What is the replacement for S25FL129P0XMFI013?

No official successor is recorded for this order code. The S25FL128P family is a common cross-shop candidate — same 128 Mbit density, SPI Quad I/O, and 16-SOIC package — but verify the command set, status register, and sector erase sizes against your firmware before substituting.

Does S25FL129P0XMFI013 support Quad SPI?

Yes, the memory interface is SPI with Quad I/O support, enabling four-bit data transfers at the 104 MHz clock for higher read throughput than standard SPI.

Is S25FL129P0XMFI013 compatible with 3.3V?

The SPI I/O levels track VCC, so a 3.3 V host interface is a direct match.
