ARM launches Cortex-M23 and M33 cores for secured cloud based IoT with

Secure processing and cloud connectivity trends drive IOT design. The main piece of IoT that need to support secure processing and cloud connectivity is the processor core. ARM has launched new processor cores for embedded microcontroller chips with focus on security and cloud connectivity. ARM has added two new Microcontroller IP to its family of ARM Cortex -M Series to target cloud connected secure IoT market. The two added products are ARM Cortex-M23 and Cortex-M33. They are the first embedded processors based on the ARMv8-M architecture. The ARMv8-M architecture adds fast and simpler hardware based security extensions with ARM TrustZone. Memory protection, separation of secure code, providing access to secure memory and I/O only to trusted software only, are some of the features of ARMv8-M architecture. ARM has said the majority of microcontroller makers have already licensed one or both of these processors . Analog Devices, Microchip, Nuvoton, NXP semiconductors, Renesas, Silicon Labs and STMicroelectronics are the companies who said to have licensed these cores. The ARM Cortex-M33 is designed to be versatile with lot of configuration features such as coprocessor interface, Digital Signal Processor and floating point computation. "As IoT technologies become more pervasive, it is time for a complete solution that secures data from the sensor to the service," said ...
