The device features seven independent 24-bit sigma-delta ADCs with differential inputs and programmable gain, providing better than 0.1% metrology accuracy over a 2000:1 dynamic range, exceeding ANSI C12.20 and IEC 62053 standards. The 25MHz MSP430 CPU with a 32-bit hardware multiplier performs all metrology calculations including active, reactive, and apparent power for up to three phases plus neutral. The 512KB Flash and 32KB RAM store metrology firmware and accumulated energy data. The LCD controller supports up to 320 segments with contrast control for meter display panels. The password-protected real-time clock (RTC) includes tamper detection and temperature-compensated crystal offset calibration. The AES-128 hardware module enables secure communication for AMI\/AMR networks. Six eUSCI interfaces support UART, SPI, and I2C communication with metrology peripherals. The ultra-low power LPM3 mode at 2.1µA preserves data during AC mains failure, with the LCD continuing to operate at only 3µA.","working_principle":"The MSP430F6779A operates as a dedicated metrology processor. The seven 24-bit sigma-delta ADCs simultaneously sample the three phase voltages, three phase currents, and neutral current. The sigma-delta modulators oversample the analog inputs at high frequency, and the integrated digital decimation filters produce 24-bit output words at up to 4kHz. The 25MHz MSP430 CPU processes the ADC samples using the Energy Measurement software library to calculate active energy (W), reactive energy (VAR), apparent energy (VA), RMS voltage, RMS current, power factor, and frequency. The 32-bit hardware multiplier accelerates the multiply-accumulate operations needed for power calculations. The AES-128 module encrypts metering data for secure transmission over AMI networks. The RTC provides time-stamping for tariff management with temperature compensation for crystal accuracy. The LCD controller multiplexes up to 320 segments for meter display. The DMA controller transfers ADC results to RAM without CPU intervention, freeing the CPU for calculation.","pin_description":"
