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 eUSCI_A modules and one eUSCI_B 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
