MSP430F1121IDW Description

There are multiple devices in the Texas Instruments MSP430 family of ultralow-power microcontrollers, each of which has a unique set of peripherals designed for a particular application. In portable measurement applications, the architecture and five low-power modes are optimized to extend battery life. The system includes a potent 16-bit RISC CPU, 16-bit registers, and constant generators that help the code run as efficiently as possible. In less than 6 s, the digitally controlled oscillator (DCO) enables wake-up from low-power modes to active mode.

An ultralow-power mixed signal microcontroller with fourteen I/O pins, a built-in 16-bit timer, and a flexible analog comparator is the MSP430x11x1(A) series.
