Texas 32-bit MSP432 microcontrollers

Thursday October 22, 2015
Oct. 22, 2015 - Texas Instruments says its MSP432 microcontroller (MCU) platform is the industry’s lowest power 32-bit ARM Cortex-M4F MCUs.

The 48MHz MCUs claim to optimize performance without compromising power, while only consuming 95uA/MHz in active power and 850nA in standby power. According to the company, the 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. In addition, a 14-bit ADC consumes 375uA at 1MSPS. MSP432 MCUs include a 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, explains the company.
