Key features and what they mean for the BOM
The 120 MHz Cortex-M4 core handles DSP and control loops. The 1 MB Flash and 640 KB SRAM support application stacks and data logging. Supply range 1.71 V to 3.6 V runs from a single Li-ion cell. On the analog side, the MCU integrates 16 channels of 12-bit ADC and two 12-bit DACs, enough for multi-channel sensor acquisition or closed-loop analog output without external converters. Connectivity includes CANbus, USB OTG, multiple SPI/I²C/UART interfaces, and an external memory interface (EBI/EMI) — covering most industrial and consumer bus requirements.
