The Infineon S25FL132K0XBHV030 is a 32 Mbit SPI NOR Flash memory from the FL1-K series, organized as 4M × 8 and operating from a 2.7 V to 3.6 V supply. The part is specified across the industrial temperature range of -40°C to 105°C and comes in a 24-ball TBGA (6 × 8 mm) package for surface-mount assembly.
The 108 MHz clock rate with quad I/O (four data lines) delivers an effective read bandwidth that outpaces a standard single-bit SPI interface at the same frequency. For a design that boots from serial Flash or streams calibration tables, this reduces read latency and frees the host MCU for other tasks. The 3 ms page/word write cycle is typical for NOR Flash and sets the expectation for firmware update timing.
