If you have an active BOM line using this part, you need to qualify a replacement or secure remaining inventory before it dries up entirely. ## 128 Mbit SPI NOR Flash — the code-storage workhorse It uses the FL-P series architecture and supports Quad I/O SPI at a clock frequency of 104 MHz, which gives read throughput suitable for execute-in-place (XIP) firmware and fast boot loading. The write cycle time is 5 µs per word and 3 ms per page, which is typical for NOR Flash of this generation. The memory interface is SPI with Quad I/O — four data lines plus clock and chip select — so the board layout needs those extra traces compared to a standard SPI part, but the read speed gain is substantial for firmware loading. The supplier device package is 16-SOIC.","metaTitle":"S25FL129P0XMFI010 Cypress FL-P 128 Mbit SPI NOR Flash","metaDescription":"S25FL129P0XMFI010 Cypress FL-P 128 Mbit SPI NOR Flash, Quad I/O, 104 MHz, 2.7–3.6 V, 16-SOIC, –40 to 85°C.

For a pin-compatible alternative in the same FL-P family, look at the S25FL128P or S25FL256P series in the same 16-SOIC package, but verify the density and Quad I/O support against your firmware image size. The Winbond W25Q128JV is a commonly cross-shopped part, but its pinout and command set are not identical — review the datasheet for your design."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL129P0XMFI010","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL129P0XMFI010 when reusing this data.
