Single-phase metering SoC with 3 Sigma-Delta ADCs, LCD, real-time clock, 64KB Flash, 4KB RAM

The TI MSP family of ultra-low-power microcontrollers consists of several devices

featuring different sets of peripherals targeted for various applications. The architecture,

combined with extensive low-power modes, is optimized to achieve extended battery life in portable

measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and

constant generators that contribute to maximum code efficiency. The DCO allows the device to wake

up from low-power modes to active mode in 3 µs (typical).

The MSP430F673xA and MSP430F672xA devices are microcontrollers with high-performance

24-bit sigma-delta ADCs (three ADCs in MSP430F673xA and two ADCs in MSP430F672xA), a 10-bit ADC,

four eUSCIs (three eUSCIA modules and one eUSCIB module), four 16-bit timers, a hardware

multiplier, a DMA module, an RTC module with alarm capabilities, an LCD driver with integrated

contrast control, an auxiliary supply system, and up to 72 I/O pins in the 100‑pin devices and 52

I/O pins in the 80‑pin devices.
