Industrial temperature grade and environment
The MSP430F6769IPEU: Rated for -40°C to 85°C ambient operation. Supply range 1.8 V to 3.6 V. Internal oscillator included; external crystal optional for metrology-grade accuracy.
Six sigma-delta ADCs — the headline feature
The six 24-bit sigma-delta converters are the main event. They enable simultaneous sampling of three-phase voltages and currents plus neutral in a polyphase meter, or six independent sensor channels in a data-acquisition front-end. The 10-bit auxiliary ADC handles housekeeping (temperature, supply monitoring) without stealing a sigma-delta channel.
