72 MHz Cortex-M4 with DSP and FPU — real-time control headroom
That core handles mixed-signal control loops — motor FOC, digital power, or multi-axis PID — without an external DSP. The 384 KB Flash and 80 KB RAM leave room for a moderate firmware image and a few KB of data logging or communication buffers. The 86 available I/O in a 100-LQFP package give you enough pins to wire up parallel displays, multiple encoder interfaces, or a bank of relay drivers without resorting to port expanders. The 14x14 mm footprint is manageable for four-layer boards; keep the analog and digital grounds split if you're using all 39 ADC channels.
Analog integration — 39-channel ADC and dual DAC
The 39-channel 12-bit ADC array covers multi-sensor acquisition. The two 12-bit DACs can generate analog setpoints or bias voltages.
It does not carry AEC-Q100 qualification.
Connectivity — CAN, USB, and serial fieldbuses
On-chip CANbus (2.0B) interfaces directly with industrial fieldbus nodes; USB full-speed handles data logging or HID-class peripherals. The I2C, SPI, and UART/USART blocks cover sensor bridges, serial displays, and Modbus RTU slaves. IrDA and LINbus are available for legacy automotive or infrared communication links. The peripheral set is fixed — no internal PHY for Ethernet or CAN FD.
