Renesas Electronics Launches Enhanced RX65N/RX651 Microcontroller to Strengthen Industrial IoT Security

Extended Microcontroller Series Adds Enhanced Flash Memory and Optimized Human Interface Interface to End Devices

Renesas Electronics Corporation, a leading global supplier of semiconductor solutions, announced today that it has expanded its popular RX65N/RX651 microcontroller (MCU) family of products to meet the higher security requirements of industrial automation, building automation and smart metering systems demand. The extended microcontroller integrates Trusted Secure IP (TSIP) and enhanced reliable flash functions and Human Machine Interface (HMI) for industrial and network control systems.

Tim Burgess, senior director of Renesas Electronics's high-end MCU division, said: "In the selection of products, industrial control system developers have placed emphasis on safety, reliability, and connectivity to the same level of performance and quality. Extended RX65N/ The RX651 MCU family provides industrial system manufacturers with the high reliability, energy efficiency, and enhanced connectivity required for industrial system operation, while providing greater security and connectivity for edge devices in increasingly connected environments. ."

Key Features of Extended RX65N/RX651 MCUs

Integrated Trusted Secure IP (TSIP)

The new MCUs with enhanced security features are based on a high-performance RXv2 core using a 40-nanometer process that enables the CPU to achieve a high efficiency of 4.55 Core Mark/MHz. By integrating TSIP into a new MCU, system control engineers can achieve high confidence levels in device operation through three new features:

Protecting encryption keys through TSIP

Integrate crypto hardware accelerators such as AES, 3DES, SHA and TRNG into TSIP

Protect boot code with flash area protection

TSIP has passed CAVP certification to ensure customers use high-security devices.
