3 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

digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active mode in 3.5 μs

(typical).
