† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

DescriptionThe Texas Instruments MSP430x43x 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 MSP430x43x 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 of MSP430x43x 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 of MSP430x43x enhances the performance and offers a broad code and hardware-compatible family solution.
