Texas Instruments, Inc. (TI) today announced its MSP432™ microcontroller (MCU) platform, claimed to be the industry’s lowest power 32-bit ARM® Cortex®-M4F MCUs. These 48MHz MCUs leverage TI’s ultra-low-power MCU expertise to optimize performance without compromising power, while only consuming 95µA/MHz in active power and 850nA in standby power. Industry-leading integrated analog, such as a high-speed 14-bit 1MSPS analog-to-digital converter (ADC), further optimizes power efficiency and performance. MSP432 MCUs enable designers to develop ultra-low-power embedded applications such as industrial and building automation, industrial sensing, industrial security panels, asset tracking and consumer electronics where both efficient data processing and enhanced low-power operation are essential.

The new MSP432 MCUs are the latest advancement in TI’s ultra-low-power innovation, delivering a best-in-class ULPBench™ score of 167.4 – outperforming all other Cortex-M3 and -M4F MCUs on the market. This ultra-low power benchmark (ULPBench) from the Embedded Microprocessor Benchmark Consortium (EEMBC) provides a standard way to compare power performance on any MCU, independent of architecture. The integrated DC/DC optimizes power efficiency at high-speed operation, while an integrated LDO reduces overall system cost and design complexity.

MSP432 MCUs pack more performance into devices without compromising power budgets. The integrated digital signal processing (DSP) engine and floating-point core (FPU) of the ARM Cortex-M4F core enable a multitude of high performance applications, such as signal conditioning and sensor processing, while maintaining performance headroom for product differentiation. MSP432 MCUs include up to 256 KB flash and boost performance with dual-bank flash memory that enables simultaneous read and write functionality.
An advanced encryption standard (AES) 256 hardware encryption accelerator enables developers to secure their device and data, while IP protection features on MSP432 MCUs ensure data and code security. These features result in higher throughput, more integration of advanced algorithms, wired or wireless Internet of Things (IoT) stacks and higher resolution display images – all while operating within an existing power budget.

Additional features and benefits of TI’s new 32-bit MSP432 MCU platform include: Code, register and low-power peripheral compatibility between MSP430 and MSP432 portfolios enables developers to leverage existing code and port code between 16- and 32-bit devices. EnergyTrace+™ technology and ULP Advisor software monitor power consumption in real time with ±2 percent accuracy. All-inclusive, power-optimized MSPWare™ software suite includes libraries, code examples, documentation and hardware tools for 16- and 32-bit MSP MCUs and can be accessed online with TI’s Resource Explorer or Code Composer Studio™ (CCS) IDE. Additional support through IAR Embedded WorkBench® and ARM Keil® MDK IDEs.
The MSP432P401RIPZ MCU is available for immediate sampling. Upcoming devices will be available with a wide variety of features, packages sizes and up to 256 KB flash starting at USD $2.15 in 1K units. Developers can start designing with MSP432 MCUs using the MSP-EXP432P401R LaunchPad kit for $12.99 or the MSP-TS432PZ100 target board for $89.
