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 five 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 µs (typical).
The MSP430F663x series are microcontroller configurations with a high-performance 12-bit analog-to-digital
converter (ADC), comparator, two universal serial communication interfaces (USCIs), USB 2.0, a hardware
multiplier, DMA, four 16-bit timers, a real-time clock module with alarm capabilities, an 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, and hand-held meters.

web site at http://www.ti.com.
(2) Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at

(3) The additional 2 KB USB SRAM that is listed can be used as general purpose SRAM when USB is not in use.
(4) 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.
(5) 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.
