The Texas Instruments MSP430 family of low-power microcontrollers consists of several devices that feature 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 the device to wake up from low-power modes to active mode in less than 10 µs.

MSP430FR4133 LaunchPad開發(fā)板
The MSP-EXP430FR4133 LaunchPad development kit is an easy-to-use Evaluation Module (EVM) for the MSP430FR4133 microcontroller. It contains everything needed to start developing on the MSP430 Ultra-low-power (ULP) FRAM-based microcontroller (MCU) platform, including on-board emulation for programming, debugging and energy measurements. The board features on-board buttons and LEDs for quick integration of a simple user interface as well as a Liquid Crystal Display (LCD) display which showcases the integrated driver with flexible software-configurable pins. The MSP430FR4133 device features embedded FRAM (Ferroelectric Random Access Memory), a non-volatile memory known for its ultra-low power, high endurance and high speed write access.
Rapid prototyping is simplified by the 20-pin BoosterPack™ plug-in module headers, which support a wide range of available BoosterPacks. You can quickly add features like wireless connectivity, graphical displays, environmental sensing, and much more. Design your own BoosterPack or choose among many already available from TI and third party developers. The out-of-box provided with the MSP-EXP430FR4133 LaunchPad features the on-board segmented display and offers two operating modes. Stopwatch Mode can run a timer for up to 100 hours, or alternatively operate split time, where the display can be frozen and the stopwatch continues running in the background. The second mode provides a simple thermometer application using the on-chip temperature sensor. The temperature is displayed on the LCD and can be shown in degrees Fahrenheit or Celsius. Free software development tools are also available, such as TI’s Eclipse-based Code Composer Studio and IAR Embedded Workbench. Both of these IDEs support EnergyTrace technology when paired with the MSP430FR4133 LaunchPad. More information about the LaunchPad, the supported BoosterPacks and available resources can be found at TI’s LaunchPad portal.
