Description

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 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 devices.
