Description

The TI MSP family of ultra-low-power microcontrollers consists 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 contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active mode in less than 5 µs.

The MSP430F543x and MSP430F541x microcontrollers have three 16-bit timers, a high-performance 12-bit analog-to-digital converter (ADC), up to four universal serial communication interfaces (USCIs), a hardware multiplier, DMA, a real-time clock (RTC) module with alarm capabilities, and up to 87 I/O pins.

For complete module descriptions, see the MSP430F5xx and MSP430F6xx Family User’s Guide.
