Dual 24-bit ADC + 10-bit ADC — three analog paths
Two independent 24-bit sigma-delta ADCs handle the voltage and current channels for each phase in a polyphase energy meter, while the 8-channel 10-bit SAR ADC monitors auxiliary inputs (temperature, tamper detect, neutral current). This partitioning lets the 24-bit converters run continuously at high resolution without interrupting the 10-bit scan for housekeeping.
Integrated LCD driver — no external controller needed
Industrial temperature range and package
Rated for -40°C to 85°C ambient, this MCU suits outdoor meter cabinets, factory-floor controllers, and telecom base-station equipment. It comes in a 100-pin LQFP (14x14 mm) — a standard footprint that routes easily on a 4-layer board with the analog and digital domains separated.
