The importance of maintaining node security is emerging as global network connectivity strengthens.
Next-generation model provides improved energy efficiency and on-chip system-level security.

Analog Devices (ADI) announced plans to launch an ultra-low power microcontroller (MCU) in collaboration with ARM that can enhance security and improve energy efficiency for Internet of Things (IoT)-based devices.

ADI announced that as the demand for data security for IoT applications increases, it will address these challenges by combining the new ARM® Cortex®-M33 processor, based on ultra-low power mixed-signal technology and ARM’s TrustZone technology.



The Cortex-M33 processor is based on the ARMv8-M architecture, which uses TrustZone technology. TrustZone technology uses hardware embedded in the processor to help protect trusted applications and data.

For ADI’s existing ultra-low power MCUs based on Cortex-M processors, power consumption is less than 38uA/MHz in operating mode and 750nA in standby mode. They expressed anticipation that next-generation models using the Cortex-M33 would offer improved energy efficiency and on-chip system-level security features.

"We are very pleased to expand our relationship with ARM and provide ultra-low-power MCUs, which enables a higher level of intelligence locally implemented at nodes and allows for the use of more complex algorithms," said Mark Cox of ADI’s IoT Platform Group. He continued, "IoT products based on the next-generation Cortex-M33 are the result of combining ADI’s leading technology in energy efficiency and reliability with a security architecture that protects customers and their product users. IoT device designers no longer need to sacrifice functionality or reliability to increase efficiency. This is because MCUs powered by ADI’s Cortex-M33 possess the complete set of security and trust solutions essential for various IoT applications, ranging from remote health monitoring and wearable devices to industrial automation and smart cities."

ADI recently acquired Sypris Electronics' Cyber Security Solution (CSS) business.
