DESCRIPTION

The MSP430G2230 is an ultra-low-power microcontroller. 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 MSP430G2230 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.
