MSP430FR247x Ultra-Low-Power MSP430™ MCU

Texas Instruments' MSP430FR247x MCUs are part of the MSP430 value line portfolio of ultra-low-power (ULP) low-cost devices for sensing and measurement applications. The MSP430FR247x MCUs integrate a 12-bit SAR ADC and one comparator. The MSP430FR247x MCUs support an extended temperature range of -40°C to +105°C, so higher temperature industrial applications can benefit from the devices’ FRAM data-logging capabilities.

The MSP430FR247x MCUs are supported by an extensive hardware and software ecosystem with reference designs and code examples to get the design process started quickly. Development kits include the MSP-TS430PT48 48-pin target development board. TI also provides free MSP430Ware™ software, which is available as a component of Code Composer Studio™ IDE desktop and cloud versions within TI Resource Explorer. The MSP430 MCUs are also supported by extensive online collateral, training, and online support through the E2E™ Community Forum.

The MSP430 ULP FRAM MCU platform combines embedded FRAM and a holistic ULP system architecture allowing users to increase performance while lowering energy consumption. FRAM technology combines the low-energy fast writes, flexibility, and endurance of RAM with the nonvolatile behavior of Flash.

The MSP430 device's architecture is combined with extensive low-power modes to optimize and achieve extended battery life in portable measurement applications. The MCU 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 MCU to wake up from low-power modes to active-mode in less than 10 µs (typical).
