The 19-channel 12-bit ADC handles multi-sensor acquisition — temperature, pressure, current sense — without external multiplexers. The single 12-bit DAC provides one analog output for setpoint or trim voltage.
The core runs at 48 MHz, which is the maximum clock for this ARM Cortex-M0 implementation. That is sufficient for control loops and sensor fusion in the tens-of-kilohertz range.
