32 Mbit NOR Flash with Quad I/O — what it does and where it fits
The Cypress S25FL132K0XBHIS30 is a 32 Mbit NOR Flash memory from the FL1-K series, organized as 4M × 8 bits. It communicates over an SPI bus with Quad I/O support, meaning four data lines carry the read payload instead of one — a practical speed bump for code shadowing or execute-in-place (XIP) designs without adding address pins. The 108 MHz clock rate on the Quad I/O interface delivers a sustained read throughput that keeps a Cortex-M or RISC-V core fed during boot.
108 MHz clock and 3 ms page write — what the ratings mean for the BOM
The −40 °C to 85 °C operating range covers most industrial and outdoor telecom enclosures, but not extended-temperature applications like under-hood automotive or downhole drilling. If your design lives in a conditioned indoor environment, this grade is more than adequate.
