That FPU matters for sensor fusion and motor-control algorithms that would otherwise eat CPU cycles in software emulation. With 105 I/O lines in a 144-LQFP package, this MCU can handle parallel LCD interfaces, multiple UART/SPI buses, and a bank of discrete sensors without external GPIO expanders. The connectivity set includes CAN, USB OTG, I²C, SPI, SSI, UART, and QEI for quadrature encoder inputs — a natural fit for industrial drives, robotic joints, or multi-axis motion platforms.
The device operates from 1.08 V to 3.63 V.
On-chip peripherals worth noting
The integrated 12-bit ADC with 24 channels covers multiple analog inputs without external muxing — useful for reading potentiometers, current shunts, or thermistor strings in a single-cycle conversion. The motion PWM module with dead-band insertion handles H-bridge and three-phase inverter gating directly, reducing the need for a separate motor-control ASIC.
