Description

The Texas Instruments MSP430™ family of ultra-low-power microcontrollers (MCUs) 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 attribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 6 µs. The MSP430F13x, MSP430F14x, and MSP430F14x1 MCUs support two built-in 16-bit timers, a fast 12-bit ADC on the MSP430F13x and the MSP430F14x devices, one USART on the MSP430F13x devices or two USARTs on the MSP430F14x and MSP430F14x1 devices, and 48 I/O pins. The hardware multiplier enhances the performance and offers a broad code and hardware-compatible family solution. For complete module descriptions, see theMSP430x1xx Family User’s Guide.
