Renesas Launches 5V RX660 32-Bit MCUs with Superior Noise Tolerance for Home Appliances and Industrial Applications

Renesas Electronics announced a new addition to the RX 32-bit MCU Family, the RX660 group of microcontrollers (MCUs) that supports operating voltages of up to 5V, offering superior noise tolerance for home appliances and industrial equipment exposed to high electromagnetic interference. The RX660 is the first in Renesas’ higher-end RX general-purpose MCU devices to support 5V and the first in the RX Family to feature a built-in CAN FD controller that enables fast data communication. The high operating voltages of the new RX660 MCUs eliminate the need for external noise-suppression components that are required for many 3V MCUs today.

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 10% higher than on the earlier RX210, which is also 5V compatible (more info).
