Renesas RX MCU Distributor | 32-bit RX Family MCUs
Renesas RX 32-bit microcontrollers with a proven core for industrial, networking and general embedded designs.
RX 32-bit MCUs Overview
BeiLuo supplies genuine Renesas RX microcontrollers, the 32-bit family built around Renesas's own RX CPU core, which is known for its high code efficiency and its deterministic performance. The RX family has been in production for many years and is widely used in industrial control, networking, office equipment and consumer products, and its parts share a common architecture, a common toolchain and a broad set of middleware, so code and drivers move between devices with modest change. The RX65N provides the RX core at up to 120 MHz with a large flash complement and a TFT controller, which suits HMI and connected products, while the RX63N provides the core at up to 100 MHz with Ethernet, USB and security functions for networking and control. Because the family has a long production history and a broad ecosystem, it is a dependable choice for products with long service lives, and it offers a migration path within the architecture. 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 migration from an older part and verify the peripheral and package fit. Because the family has a long production history, we also help customers plan the lifecycle of a long-service product.

Frequently Asked Questions
Why choose the RX family over an Arm Cortex-M?
The RX core is known for high code efficiency and deterministic performance, and the family has a long production history and a broad middleware ecosystem, which suits products that value proven behaviour and long service life.
For a new design that wants a Cortex-M and a modern software package, the RA family is the alternative.
Can I migrate from an older RX part?
Yes. The RX family provides a migration path within the architecture, and pin compatibility between related parts simplifies a change.
Read the RX migration application note for the details.
What connectivity does the RX family offer?
The RX parts provide Ethernet, USB and a range of serial interfaces, and the higher-performance members add a TFT controller for HMI.
Confirm the interface count against your design.
