256 Mbit NOR Flash with 133 MHz SPI Quad I/O
133 MHz clock — read throughput for firmware boot and OTA
The 133 MHz SPI clock is the headline performance spec. In Quad I/O mode, that translates to a sustained read rate that keeps a Cortex-M or RISC-V core fed during boot, and slashes the time for over-the-air update staging.
Industrial temp range — deployment in outdoor or factory gear
The 24-TBGA package (6x8 mm) keeps the board footprint small, but rework needs a hot-air station — not a field-swap job without a bench.
