Cypress officially lists the S25FL132K0XNFI043 as Obsolete. That means no further production runs; the only channel is surplus inventory or broker stock. For an existing BOM, a last-time buy may have already closed — verify date codes and remaining shelf life before committing to a large reel.
32 Mbit NOR Flash with 108 MHz Quad I/O — what it delivers
The S25FL132K0XNFI043 is a 32 Mbit (4 M x 8) SPI NOR Flash from Cypress's FL1-K series. It supports Quad I/O at a clock frequency of 108 MHz, which gives a practical read throughput high enough for execute-in-place (XIP) firmware on a moderate-speed MCU.
Industrial temperature range — where it works
The 3 ms page write cycle time is standard for NOR; it governs the firmware-update speed during OTA or in-system programming.
