1.3 Description
The Texas Instruments MSP430™ family of ultra-low-power microcontrollers consists of several devices
featuring different sets of peripherals targeted for various applications. The architecture, combined with
five 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 less than 1 µs.
The MSP430G2x44 series is an ultra-low-power mixed-signal microcontroller with two built-in 16-bit timers,
a universal serial communication interface (USCI), 10-bit analog-to-digital converter (ADC) with integrated
reference and data transfer controller (DTC), and 32 I/O pins.
