TI's MSP432 microcontroller (MCU) platform claims to be industry’s lowest power 32-bit ARM Cortex-M4F MCUs.
To create the low power architecture solution, TI opted to build the MSP432 around the Cortex-M4F core architecture rather than ARM's Cortex-M0 core following the realisation that traditional industrial control applications and future Internet of Things applications require a more feature-rich solution that is low in power usage.
The 48 MHz MCUs apply TI’s ultra-low-power MCU expertise to optimize performance without compromising power, while consuming 95 µA/MHz in active power and 850 nA 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 MSP432 MCUs claim to deliver a best-in-class ULPBench score of 167.4 – outperforming all other Cortex-M3 and -M4F MCUs on the market. The 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.
