1 Billionth of 32-bit RX MCU Family Ships

Renesas Electronics has announced that it has delivered more than one billion microcontrollers from the RX Family of 32-bit MCUs, which incorporate Renesas’ proprietary RX CPU core. Since its launch in 2009, the RX Family has expanded to include general-purpose, motor control, touch sensing and industrial Ethernet applications. The MCUs have been adopted in a wide range of consumer, industrial and IoT applications. In the home air conditioner compressor market, for example, RX MCUs’ outstanding inverter control has led to adoption by more than 70% of major manufacturers around the world, says Renesas.

RX MCUs deliver high CPU performance due to their sophisticated architecture for embedded systems, says the company. Currently, four series of RX MCUs are available (RX100, RX200, RX600 and the high-end RX700) offering a wide range of performance, on-board memory, and a variety of peripheral functions and packages. Following the introduction of the latest RXv3 core in 2018, Renesas is also working on the development of the next core with the aim of surpassing the performance of the RXv3 core.

In order to ease implementation of RX MCUs, Renesas offers a smart configurator and code generator in response to the growing need for low and no code to reduce the development burden of embedded systems. Renesas continually works to expand the development environment to improve user experience (UX), shorten development time, and reduce development cost.

RX MCUs are key products in “Winning Combinations” that combine numerous products within the Renesas portfolio that work together seamlessly. Examples of Winning Combinations featuring the RX devices include the AC Drives/GP Inverters Solution and High-Voltage Motor Driver Solution. In 2021, during COVID-19, Renesas provided a ventilator solution Winning Combination that contributed to saving lives. Furthermore, with the desire to minimize physical contact from a hygiene standpoint, there are a growing number of applications in non-contact applications, such as “touch-free user interface reference design,” which utilize robust and reliable capacitive touch sensing technology.

As a result of their performance advantages in a wide range of applications, RX MCUs are expected to achieve a record high growth of more than 30% in 2021, with sales exceeding 35 billion yen. Renesas has announced that it will step up investment in production capacity. In 2022, by combining internal production with outside foundries, Renesas will establish a more flexible production system that will support expected growth in the RX MCU family of more than 30% over 2021.

Renesas says it will further strengthen its connectivity and robust security technologies for cloud connectivity for the future of smart IoT applications of consumer and industrial applications. Going forward, Renesas will continue to expand the RX Family, as well as the Arm based RA Family of 32-bit MCUs, to create a rich ecosystem and broaden the range of choices for customers. Renesas wants to build a sustainable future where technology helps make our lives easier through the provision of MCUs and other semiconductor solutions.
