Single-phase metering SoC with 2 Sigma-Delta ADCs, LCD, real-time clock, 32KB Flash, 2KB 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 digitally controlled oscillator

(DCO) allows the device to wake up from low-power modes to active mode in 3 µs (typical).

The MSP430F673x and MSP430F672x microcontrollers feature up to three high-performance

24-bit sigma-delta ADCs, a 10-bit ADC, four enhanced universal serial communication interfaces

(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.
