The TI MSP430 family of ultra-low-power microcontrollers consists of several devices featuring different sets of peripherals targeted for various applications. The architecture, combined with extensive 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 3.5 µs (typical).
The MSP430F543xA and MSP430F541xA series are microcontroller configurations with three 16-bit timers, a high-performance 12-bit ADC, up to four universal serial communication interfaces (USCIs), a hardware multiplier, DMA, an RTC module with alarm capabilities, and up to 87 I/O pins.
Typical applications for this device include analog and digital sensor systems, digital motor control, remote controls, thermostats, digital timers, and hand-held meters.
