MSP430G2553IPW20

The MSP430 series of ultra-low-power microcontrollers includes a variety of devices, each featuring a distinct set of peripherals tailored for multiple applications. This architecture, combined with five low-power modes, is optimized to extend battery life in portable measurement applications. The device is equipped with a powerful 16-bit RISC CPU, 16-bit registers, and a constant generator that aids in achieving maximum coding efficiency. The Digital Control Oscillator (DCO) can wake up from a low-power mode to an operating mode in less than 1µs. The MSP430G2x13 and MSP430G2x53 series are ultra-low-power mixed-signal microcontrollers. They come with a built-in 16-bit timer, up to 24 I/O pins supporting touch sensing, a multi-purpose analog comparator, and built-in communication capabilities using a Universal Serial Communication Interface. Additionally, members of the MSP430G2x53 series also feature a 10-bit Analog-to-Digital (A/D) converter. Typical applications include low-cost sensor systems, which are responsible for capturing analog signals, converting them into digital values, and then processing the data for display or transmission to a host system.
