The MSP430F643x series are microcontroller configurations with an integrated 3.3-V LDO, a high-performance
12-bit analog-to-digital (A/D) converter, comparator, two universal serial communication interfaces (USCI),
hardware multiplier, DMA, four 16-bit timers, real-time clock module with alarm capabilities, LCD driver, and up to
74 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.
