DESCRIPTION
The Texas Instruments MSP430™ family of ultra-low-power microcontrollers consist 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 wake-up from low-power modes to active mode in less than 1 μs.
The MSP430G22x0 series is an ultra-low-power mixed signal microcontroller with a built-in 16-bit timer and four
I/O pins. In addition, the MSP430G2230 has a built-in communication capability using synchronous protocols
(SPI or I2C) and a 10-bit A/D converter. The MSP430G2210 has a versatile analog comparator.
