DESCRIPTION
The Texas Instruments MSP430 family of ultralow-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 wake-up from low-power modes to
active mode in less than 5 µs.
The MSP430F543xA and MSP430F541xA series are microcontroller configurations with three 16-bit timers, a
high performance 12-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 to 87 I/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.
Family members available are summarized in Table 1.

(1) Each number in the sequence represents an instantiation of Timer_A with its associated number of capture compare registers and PWM
output generators available. For example, a number sequence of 3, 5 would represent two instantiations of Timer_A, the first
instantiation having 3 and the second instantiation having 5 capture compare registers and PWM output generators, respectively.
(2) Each number in the sequence represents an instantiation of Timer_B with its associated number of capture compare registers and PWM
output generators available. For example, a number sequence of 3, 5 would represent two instantiations of Timer_B, the first
instantiation having 3 and the second instantiation having 5 capture compare registers and PWM output generators, respectively.
