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 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 analog-to-digital converter (ADC), up to four universal serial communication interfaces
(USCIs), a hardware multiplier, DMA, a 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, and hand-held meters.

(3) 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.
(4) 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.
