3 Description

MSP430FR247x microcontrollers (MCUs) are part of the MSP430™ MCU value line portfolio of ultra-low-power

low-cost devices for sensing and measurement applications. MSP430FR247x MCUs integrate a 12-bit SAR

ADC and one comparator. The MSP430FR247x MCUs support an extended temperature range from –40°C

up to 105°C, so higher temperature industrial applications can benefit from the devices' FRAM data-logging

capabilities.

MSP430FR247x MCUs are supported by an extensive hardware and software ecosystem with reference designs

and code examples to get your design 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 withinTI Resource Explorer. MSP430 MCUs are also

supported by extensive online collateral, such as our housekeeping example series, MSP Academy training, and

online support through the TI E2E™ support forums.

The MSP430 ultra-low-power (ULP) FRAM microcontroller platform combines uniquely embedded FRAM and a

holistic ultra-low-power system architecture, allowing system designers 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 TI MSP430 family of low-power microcontrollers consists of devices with 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 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).
