Peripheral set — what it actually does on the board
The 4x24b sigma-delta converter is the headline block. It samples multiple voltage and current channels simultaneously, which is exactly what a polyphase energy meter or a precision weigh-scale needs. The LCD controller drives a segmented glass display directly — no external display driver IC. The 8-channel 10-bit auxiliary ADC handles housekeeping (temperature, supply monitoring). The internal oscillator keeps the BOM count low, though an external crystal can be used for tighter timing on the sigma-delta sampling window.
