Texas Instruments (TI) today announced its MSP432™ microcontroller (MCU) platform, the industry’s lowest power 32-bit ARM® Cortex®-M4F MCUs.
These new 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 world’s lowest power Cortex-M4F MCU. Period.
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. In addition, a 14-bit ADC consumes 375µA at 1MSPS. MSP432 MCUs include a unique selectable RAM retention feature that provides dedicated power to each of the eight RAM banks needed for an operation, so overall system power can be reduced by 30nA per bank. MSP432 MCUs can also operate as low as 1.62V and as high as 3.7V with full-speed operation to lower overall system power. As the flagship product in TI’s growing 32-bit ultra-low-power MSP MCU portfolio, developers can expect the MSP432 MCU roadmap to include increasing levels of analog, integration and up to 2MB flash memory, while extending MSP430™ ultra-low-power leadership.
