DESCRIPTION
The Texas Instruments 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 wake-up from low-power modes to active mode in 3 µs
(typical).
The MSP430F67xx series are microcontroller configurations with three high-performance 24-bit sigma-delta A/D
converters, a 10-bit analog-to-digital (A/D) converter, four enhanced universal serial communication interfaces
(three eUSCI_A and one eUSCI_B), four 16-bit timers, hardware multiplier, DMA, real-time clock module with
alarm capabilities, LCD driver with integrated contrast control, auxiliary supply system, and up to 72 I/O pins in
100-pin devices and 52 I/O pins in 80-pin devices.
Typical applications for these devices are 2-wire and 3-wire single-phase metering, including tamper-resistant
meter implementations.
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.
