The RA6M4 microcontrollers are intended to quicken the design of edge and endpoint IoT devices.
The MCUs are manufactured on an efficient 40 nm process to provide exceptional power efficiency with only 99 μA/MHz in active mode. They use a 200 MHz Arm Cortex-M33 core, which is based on the Armv8-M architecture with Arm TrustZone technology. To support the core, the MCUs also offer 1 Mbyte of code flash memory, 256 Kbytes of SRAM, and a capacitive touch sensing unit.
The RA6M4 devices have been developed to provide outstanding security capabilities These capabilities include an integrated security cryptography module with several accelerators, power analysis resistance, and tamper detection. The MCUs are supported by Renesas’ Flexible Software Package (FSP). The FSP allows quick implementation of complex security and connectivity functions by allowing the reuse of legacy code. This legacy code can be combined with software from other Arm partners. The FSP also provides tools that increase efficiency, quickening the development process for projects.
The support the MCU family, Mouser will also stock the RA6M4 evaluation kit to provide 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.
Speaking at the original launch of the range, Roger Wendelken, Senior Vice President of Renesas’ IoT and Infrastructure Business Unit said, “The RA6M4 MCUs offer customers best-in-class performance and security enhancements built with Arm Cortex-M33 cores that clearly deliver more memory, memory interface expansion, better power efficiency and wake-up time, and more connectivity options,” said “We intend to delight our customers who appreciate the higher level of security and IoT connectivity that the RA6M4 MCU Group brings with the confidence and ease of use that only comes by designing with Arm and securing with Arm TrustZone technology.”
