MSP430G2744IDA38R

The MSP430G2x44 series is an ultra-low-power mixed-signal microcontroller with 2 built-in 16-bit timers, 1 universal serial communication interface (USCI), a 10-bit analog-to-digital converter (ADC) with integrated reference and data transfer controller (DTC), and 32 input/output (I/O) pins. This architecture, combined with 5 low-power modes, is optimized for extending battery life in portable measurement applications. The device features a powerful 16-bit RISC CPU, 16-bit registers, and a constant generator to help achieve maximum coding efficiency. The digitally controlled oscillator (DCO) enables the device to wake up from a low-power mode to an active mode in less than 1µs.
