Renesas Launches 5V RX660 32-Bit MCUs with Superior Noise Tolerance for Home Appliances and Industrial Applications
First RX Family MCUs with CAN FD Bus Protocol Enable High-Speed Communication for Industrial Equipment and Robotics

In recent years, the scale of software has grown as functional safety and security have become a critical part of electronic systems. As the number of product models has also increased, more products are equipped with realtime operating systems in order to simplify software maintenance. Additionally, products need to be designed to accommodate future functional enhancements using over-the-air (OTA) updates. To meet these needs, Renesas developed the RX660 using its RXv3 core (6.00 CoreMark/MHz) with a maximum operating frequency of 120 MHz, offering high performance and excellent power efficiency. The devices feature large-capacity ROM of up to 1 megabyte (MB) and RAM of up to 128 kilobytes (KB) and are available in many package options (48-pin to 144-pin). In particular, the effective pin count for general-purpose I/O pins is
“Noise suppression is essential for home appliances and industrial products since ambient electromagnetic waves in the surrounding environment can cause system malfunctions or reduce performance,” said
“At Daikin, we have been using Renesas’ RX MCUs in our main air conditioner products for over 10 years, and we welcome the new RX660 MCUs with superior noise tolerance,” said
First RX Family MCUs with CAN FD Support
CAN is becoming widely popular in industrial equipment and robotics, but the increasing volume of data communication due to the use of many sensors is causing insufficient bandwidth and higher costs for requiring multiple buses. The RX660 is the first group in the RX Family to integrate a CAN FD controller that supports fast, high-volume data transfer. CAN FD allows security signals in large volume to be transmitted in a single frame, making it possible to build stronger security into devices.
Two Development Boards Available
Two development boards are available for the RX660 group for both prototyping and detailed evaluation.
Winning Combinations
Renesas has combined the RX660 with a variety of analog and power management devices for power conversion systems to create the “On-line Type UPS (Uninterruptible Power Supply) Winning Combination.” The solution efficiently integrates all the key power conversion components including inverters, buck regulators, battery boost regulators, and PFC in a single chip, and offers the ability to remotely monitor activities via Bluetooth. Renesas offers more than 300 Winning Combinations with a wide range of products from the Renesas portfolio to enable customers to speed up the design process and bring their products to market more quickly.
