Renesas Electronics Corporation today announced the expansion of its 32-bit RA Family of microcontrollers (MCUs) with a new Group based on the latest Arm® Cortex®-M33 core. The new 100-MHz RA4E1 Group has best-in-class power consumption balanced with high performance and optimized feature integration. It enables fast design cycles and easy upgrades to other RA Family devices.

Renesas’ RA Family now boasts over 150 parts ranging from 48MHz to 200MHz. The RA Family MCUs offer industry-leading power consumption specifications, a very wide range of communications options, and best-in-class security options, including Arm TrustZone® technology. All RA devices are supported by the Renesas Flexible Software Program (FSP) that includes highly efficient drivers and middleware to ease the implementation of communications and security. The FSP’s GUI simplifies and accelerates the development process. It enables flexible use of legacy code as well as easy compatibility and scalability with other RA Family devices. Designers using FSP also have access to the extensive Arm ecosystem, offering a wide range of tools that help speed time-to-market, as well as Renesas’ extensive partner network.

“Our RA Family continues to exceed expectations by delivering market-leading performance, features, ease-of-design and value,” said Roger Wendelken, Senior Vice President in the IoT and Infrastructure Business Unit at Renesas. “The new RA4E1 Group was developed to meet the requests of our customers to extend the already-wide RA product family with an Entry-line option. We’re confident that these parts will hit the sweet spot for a wide range of applications, and that many designers will find that the RA family meets their needs for current and future developments.”

The RA4E1 MCUs are the first Entry-Line Group in the 100-MHz RA4 Series. The group includes four different parts, spanning from 48-pin to 64-pin packages, and from 256kB to 512kB of flash memory along with 128kB of SRAM. The RA4E1 devices offer the lowest active power consumption in their class, using only 60µA / MHz while executing from Flash at 100MHz. They deliver an optimized combination of innovative peripherals, connectivity options and system cost saving features. The RA4E1 Group is ideal for cost-sensitive applications and other systems requiring an optimal combination of performance and low power consumption.

All the new RA4E1 MCUs are available now. More information is available for the RA4E1 MCU Group at renesas.com/ra4e1.
