RA Arm Cortex-M MCUs Overview

BeiLuo supplies genuine Renesas RA microcontrollers, the Arm Cortex-M family that Renesas built for modern embedded designs with a strong focus on human-machine interface, capacitive touch and connectivity. The RA family spans Cortex-M23 and Cortex-M33 low-power and security devices and Cortex-M4 devices for mainstream and high-performance work, all sharing a common software package and a common development environment, so code and drivers move between parts with modest change. The RA4M1 offers a Cortex-M4 core at up to 48 MHz with a segment LCD controller and a capacitive touch sensing unit, which makes it a practical choice for appliances, instruments and other products with a display and touch interface. The RA6M3 adds a high-performance Cortex-M4 core at up to 120 MHz with a TFT controller, a 2D graphics accelerator and a JPEG decoder, which suits graphical HMI and connected products. Because the family shares the Flexible Software Package and a common toolchain, a product line can scale from a small display controller to a graphics-capable device without rewriting the application. Every device BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose a device, plan the touch and display design and verify the peripheral and package fit.

Frequently Asked Questions

How do I choose between the RA4M1 and RA6M3?

Choose the RA4M1 for a display and touch product with modest compute, such as an appliance or an instrument, and the RA6M3 when the design needs high performance, a TFT controller and graphics acceleration.

Both share the Flexible Software Package and a common toolchain.

Does the RA family support capacitive touch?

Yes. The RA4M1 includes a capacitive touch sensing unit, which lets a product implement touch buttons and sliders without external touch controllers.

Confirm the touch channel count against your design.
