•For Complete Module Descriptions,See the
MSP430x5xx Family User's Guide(SLAU208)
The Texas Instruments MSP430family of ultralow-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 powerful16-bit RISC CPU,16-bit registers,and constant generators that contribute to maximum code efficiency. The digitally controlled oscillator(DCO)allows wake-up from low-power modes to active mode in less than5µs. The MSP430F543x(A)and MSP430F541x(A)series are microcontroller configurations with three16-bit timers,a high performance12-bit analog-to-digital(A/D)converter,up to four universal serial communication interfaces (USCI),hardware multiplier,DMA,real time clock module with alarm capabilities,and up to87I/O pins.
Typical applications for this device include analog and digital sensor systems,digital motor control,remote controls,thermostats,digital timers,hand-held meters,etc.
