Renesas Electronics RA4E2 Microcontrollers

Mouser Electronics, Inc. now stocks the RA4E2 microcontrollers (MCUs) from Renesas Electronics. Featuring a 100 MHz Arm Cortex-M33 core, the MCUs offer an entry-level solution for the design of low-memory, low-pin-count, small-package applications. The MCUs are designed to deliver high-speed performance for applications including smart home devices, consumer electronics, medical devices and industrial sensor networks.

The microcontrollers feature a range of peripherals, including a 12-bit analog-to-digital converter, a general PWM timer, USB FS device, SCI, SPI, I3C, SSI, CANFD and HDMI-CEC. The MCUs are compatible with the Open Arm ecosystem, while the devices’ flexible software package supports easy development and migration for a range of designs and applications. The MCUs include 128 KB code Flash memory, 40 KB SRAM and 4 KB data flash.

The microcontrollers are supported by the RA4E2 evaluation kits. The evaluation kits enable users to evaluate the features of the MCU group and develop embedded systems applications using the flexible software package and e2 studio integrated development environment (IDE). The onboard features along with a range of popular ecosystem add-ons can serve as starting points for designers to develop their custom applications.
