description
The Texas Instruments MSP430 series is an ultralow-power microcontroller family consisting of several devices
featuring different sets of modules targeted to various applications. The microcontroller is designed to be battery
operated for use in extended-time applications. The MSP430 achieves maximum code efficiency with its 16-bit
RISC architecture, 16-bit CPU-integrated registers, and a constant generator. The digitally-controlled oscillator
provides wake-up from low-power mode to active mode in less than 6
s. The MSP430x43x and the
MSP430x44x series are microcontroller configurations with two built-in 16-bit timers, a fast 12-bit A/D converter,
one or two universal serial synchronous/asynchronous communication interfaces (USART), 48 I/O pins, and
a liquid crystal driver (LCD) with up to 160 segments.
Typical applications include sensor systems that capture analog signals, convert them to digital values, and
process and transmit the data to a host system, or process this data and displays it on a LCD panel. The timers
make the configurations ideal for industrial control applications such as ripple counters, digital motor control,
EE-meters, hand-held meters, etc. The hardware multiplier enhances the performance and offers a broad code
and hardware-compatible family solution.
