ARM today announced the ARM Cortex-M0+ processor, the world’s most energy-efficient microprocessor. The Cortex-M0+ processor has been optimized to deliver ultra low-power, low-cost MCUs for intelligent sensors and smart control systems in a broad range of applications including home appliances, white goods, medical monitoring, metering, lighting and power and motor control devices.

The 32-bit Cortex-M0+ processor, the latest addition to the ARM Cortex processor family, consumes just 9µA/MHz on a low-cost 90nm LP process, around one third of the energy of any 8- or 16-bit processor available today, while delivering significantly higher performance.

This industry-leading combination of low power and high performance provides users of legacy 8- and 16-bit architectures with an ideal opportunity to migrate to 32-bit devices, thereby delivering increased intelligence to everyday devices, without sacrificing power consumption or area.

The Cortex-M0+ processor features enable the creation of smart, low-power microcontrollers to provide efficient communication, management and maintenance across a multitude of wirelessly connected devices, a concept known as the ‘Internet of Things.’

This low power connectivity has the potential to enable a range of energy-saving and life-enhancing applications from sensors to wirelessly analyze the performance and control of domestic or industrial buildings, to battery-operated body sensors wirelessly connected to health monitoring equipment. Current 8-bit and 16-bit MCUs lack the intelligence and functionality to deliver these applications.

“The Cortex-M0+ processor is yet another demonstration of ARM low-power leadership and its commitment to drive the industry forward towards ever lower power consumption,” said Mike Inglis, EVP and GM, Processor Division, ARM. “With our expertise in low-power technology, we have worked closely with our Partners on the definition of the new processor to ensure that it can enable the low-cost devices of today, while also unlocking the potential benefits delivered by the Internet of Things.” 

Early licensees of the Cortex-M0+ processor include Freescale and NXP Semiconductor.

The ARM Cortex-M0+ could enable a ton of new smart devices. I have though seen many of these miniature systems fail to adopt in mass scale. Maybe the low power consumption is though the key to make the Internet of Things a reality.
