The 7x24-bit sigma-delta converter array allows a single MSP430F6778 to digitize voltage and current from a three-phase, four-wire system plus neutral, with no external multiplexer or timing skew.
The 25 MHz clock rate is sufficient for real-time metrology calculations, communication protocol handling, and periodic data logging.
A pin-compatible alternative within the MSP430F6xx family should be evaluated for new designs. The base product number is MSP430F6778; check the MSP430F6779 or other F6xx variants with similar peripheral sets for a drop-in replacement.
The supply voltage range is 1.8 V to 3.6 V (Vcc/Vdd).
The CPU core runs at 25 MHz.
