The S25FL132K0XMFV041 is a 32 Mbit (4M x 8) serial NOR Flash memory from Infineon's FL1-K series. It uses a SPI interface with Quad I/O support, clocked at up to 108 MHz. The Quad SPI mode allows four-bit-wide data transfers, improving read throughput for code shadowing or data logging compared to single-bit SPI.
8-SOIC package — board-fit note
The 8-pin footprint is standard for serial NOR Flash and shares pin compatibility with many other 8-SOIC SPI Flash devices, simplifying layout reuse.
