The MCUs have been designed to provide connectivity, security, and improved levels of performance, in order to speed the development of edge and endpoint Internet of Things (IoT) devices, as well as applications such as metering, HVAC, enhanced premises security, and industrial equipment.
The RA6M4 microcontrollers have been built on an efficient 40 nm process and offer exceptional power efficiency with 99 μA/MHz in active mode. They contain a 200 MHz Arm Cortex-M33 core based on the Armv8-M architecture with Arm TrustZone technology, and come with 1 Mbyte of code flash memory, 256 Kbytes of SRAM, and a capacitive touch sensing unit.
The RA6M4 devices deliver security capabilities, including an integrated security cryptography module with several accelerators, power analysis resistance, and tamper detection. The microcontrollers are supported by Renesas’ Flexible Software Package (FSP), which enables rapid implementation of complex security and connectivity functions by allowing customers to reuse legacy code and combine it with software from other Arm partners.
The FSP also offers tools to increase efficiency, accelerating the development process for projects targeting the RA6M4 microcontrollers.
Mouser is also stocking the RA6M4 evaluation kit, which offers native pin access through four 40-pin male headers, as well as access to Ethernet connectivity, 64 Mbytes of external Octo-SPI flash, and 32 Mbytes of external Quad-SPI flash.
