MSP430FR2476TRHBR FRAM Microcontroller IC 16-Bit 16MHz 64.5KB (64.5K X 8) FRAM 32-VQFN (5x5)


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).
