Renesas has expanded its 32-bit RA Family of microcontrollers (MCUs) with a new Group based on the latest Arm Cortex-M33 core.

These MCUs are available from distributor Anglia Components.

The new 100-MHz RA4E1 Group enable fast design cycles and easy upgrades to other RA Family devices.

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.

Power consumption is 60µA / MHz while executing from Flash at 100MHz, combined with an optimised 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.

The 32-bit microcontrollers use the high-performance Arm Cortex-M33 core with TrustZone. Built on a highly efficient 40nm process they are supported by an open and flexible ecosystem concept—the Flexible Software Package (FSP).

The RA4E1 is suitable for entry IoT applications requiring value optimised feature and connectivity integration, total system cost reduction and an optimised mixture of high performance combining 100 MHz Cortex-M33 Core with lowest active power consumption down to 81µA/MHz running the CoreMark algorithm from Flash.

Renesas' RA Family now boasts over 150 parts ranging from 48MHz to 200MHz.

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.

Support for developers is provided with the RA4E1 fast prototyping board which comes equipped with a R7FA4E10D2CFM microcontroller.

The board has a built-in SEGGER J-Link emulator circuit so developers can write/debug programs without additional tools.

In addition, with the integrated Arduino Uno and Pmod interfaces included as standard and through-hole access to all pins of the microcontroller the board is not only flexible but has high expandability.

Sample software is available to demonstrate the functionality of the MCU and for connecting between the prototyping board and various wireless modules or various sensor modules.
