MSP430FR2353 Ultra-Low-Power Low-Cost MSP430™ MCU

Texas Instruments' embedded microcontroller features four configurable signal-chain modules

Image of Texas Instruments' MSP430FR2353 Ultra-Low Power Low-Cost MSP430™ MCUTexas Instruments' MSP430FR2353 MCU is part of the MSP430 MCU value line portfolio of ultra-low-power low-cost devices designed for sensing and measurement applications. The MSP430FR2353 MCU integrates four configurable signal-chain modules called smart analog combos, each of which can be used as a 12-bit DAC or a configurable programmable-gain op-amp to meet the needs of a system while reducing the BOM and the PCB size. The device includes a 12-bit SAR ADC and two comparators. The MCU supports an extended temperature range of -40°C to +105°C allowing higher temperature industrial applications to benefit from the devices’ ferroelectric RAM (FRAM) data-logging capabilities. The temperature range makes the MCU ideal for applications such as smoke detectors, sensor transmitters, and circuit breakers.

The MSP430FR2353 MCU features a 16-bit RISC CPU, 16-bit registers, and a constant generator that contribute to maximum code efficiency. The digitally controlled oscillator (DCO) allows the device to wake up from low-power modes to active-mode typically in less than 10 µs.

The MSP430 ultra-low-power (ULP) FRAM MCU platform combines embedded FRAM and a holistic ultra-low-power system architecture which allows 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 MSP430FR2353 MCU is supported by an extensive hardware and software ecosystem with reference designs and code examples to get a user's design started quickly. Development kits include the MSP-EXP430FR2355 LaunchPad™ kit and the MSP-TS430PT48 48-pin target board. TI provides free MSP430Ware™ software, which is available as a component of Code Composer Studio™ IDE desktop and cloud versions within the TI Resource Explorer. The MCU is supported by extensive online collateral, training, and online support through the E2E™ community forum.
