8 MHz core — enough for sensor polling and display updates
8 MHz clock rate is modest by today's MCU standards, but it's well matched to the 16-bit RISC pipeline and the typical application loop: wake from low-power mode, sample a few ADC channels, update the LCD segment data, and go back to sleep.
On-chip analog: 5x16-bit ADC and 2x12-bit DAC
The 5-channel 16-bit sigma-delta ADC is the standout feature — it gives you enough resolution for precision sensor bridges without an external converter. The two 12-bit DACs can drive an analog output or a reference for a comparator. If your design needs more than five analog inputs, you'll need an external mux, but for a typical three-sensor flow meter with a display, this covers it.
