32 Mbit NOR Flash with 104 MHz Quad-SPI — what it does in the system
The Infineon S25FL032P0XMFI0109 is a 32 Mbit SPI NOR Flash from the FL-P family, organized as 4M x 8 bits. It uses a Quad I/O SPI interface that clocks at 104 MHz, giving read throughput well above single-bit SPI without adding pins.
Quad I/O at 104 MHz — read margin for code shadowing
At that speed, signal integrity on the PCB layout matters — keep the SPI trace length matched and avoid vias on the clock line. The 5 µs page program time and 3 ms sector erase time are typical for this density class; plan the write budget accordingly for OTA update windows.
Industrial temperature range and 8-SOIC footprint
MSL is not specified in the listing, so confirm moisture sensitivity with the manufacturer's datasheet if the parts sit beyond a standard floor-life window.
