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 µs. 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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

TexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
