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 devices.

For complete module descriptions, see the MSP430F5xx and MSP430F6xx Family User’s Guide.
