The S25FL132K0XNFV043 is a 32 Mbit SPI NOR Flash from Cypress's FL1-K series, organized as 4M x 8 bits. It communicates over a Quad I/O SPI interface at up to 108 MHz, suiting it for code shadowing, firmware storage, and parameter logging in embedded systems that need fast read throughput over a minimal pin count. Rated for -40°C to 105°C operation with a 2.7 V to 3.6 V supply range.
The 108 MHz clock rate with Quad I/O delivers a sustained read throughput that keeps a Cortex-M or RISC-V core fed during execute-in-place (XIP) without stalling on instruction fetches. Four data lines per cycle, versus a single-bit SPI, cut the read latency by roughly 4× for sequential accesses.
Supplied in an 8-pin SOIC (3.90 mm body width) on Tape & Reel, surface-mount.
