For BOM lines that still require this exact order code, procurement moves to the surplus and broker market.
The ARM Cortex-M3 core runs at 50 MHz, a throughput tier suited for real-time control loops, CAN message handling, and sensor fusion in industrial or automotive subsystems. At this clock rate, the flash wait state must be configured correctly during boot — the 128 KB Flash (128K x 8) and 32 KB RAM (32K x 8) provide enough headroom for a modest RTOS and protocol stack, but firmware size should be audited against the 128 KB ceiling before committing the BOM.
The 53 general-purpose I/O lines, mapped across the 100-LQFP package (14x14 mm body), give enough pins for parallel LCD data buses or multiple chip selects without external GPIO expanders.
Temperature grade and supply voltage
A brown-out detect and POR (Brown-out Detect/Reset, POR) are built in to handle supply droop without external supervisor ICs.
