Product details

128 Mbit NOR Flash with Quad-SPI — what the 104 MHz clock buys you

In Quad I/O mode that gives a sustained read throughput that can keep a Cortex-M or RISC-V core fed without waiting on the flash — useful for execute-in-place (XIP) boot or OTA staging where the memory sits directly on the main bus.

Write-cycle timing is specified at 5 µs per word and 3 ms per page — relevant for firmware-update routines where the page-erase and program latency affects the OTA window.

Frequently asked questions

Is S25FL129P0XBHIY03 obsolete?

Yes, the product status is Obsolete. Cypress has discontinued this exact order code. New production is not available; the only supply channel is surplus or broker inventory. If you are qualifying a replacement, check the S25FL128P family as a starting point, but verify pin compatibility and timing in your specific design.

Can S25FL129P0XBHIY03 be replaced by S25FL128P?

The S25FL128P is a common cross-shop candidate — same 128 Mbit density and Quad-SPI interface — but pin compatibility and timing parameters must be verified against the datasheet for your specific PCB layout and firmware. The official records do not list a direct successor, so treat the S25FL128P as a candidate for evaluation, not a guaranteed drop-in.

What is the memory size of S25FL129P0XBHIY03?

128 Mbit, organized as 16 M x 8 bits.
