Onsemi NCV-RSL15 is an ultra-low power automotive-grade wireless microcontroller with Bluetooth Low Energy connectivity. It is the industry’s lowest-power, secure wireless microcontroller, featuring the proprietary smart sense power mode. It can enable wireless connectivity of multiple sensors which can help vehicle manufacturers to reduce the cost and weight of the system by eliminating excess cabling required for sensors and in-vehicle communication. Moreover, it improves the security of the in-vehicle communication as physical hacking or risk of data theft is removed as the communication takes place over a secured wireless protocol. Furthermore, it employs ARM’s CryptoCell technology which offers high level of embedded security. The NCV-RSL15 will enable designers to add more sensors while reducing the wiring size, time of development and cost of the upcoming vehicles.

“Excelling at applications such as vehicle access and Tire Monitoring Systems, the miniature size of NCV- RSL15 makes it perfectly suited for portable remote access devices and other space-constrained in-tire and in-vehicle locations,” said Michel De Mey, vice president of the Industrial Solutions Division, onsemi. “By combining ultra-low power consumption with a tiny footprint, and the latest technology in embedded security into one device, we enable our customers to meet their complex sensing-related design challenges for wireless-enabled automotive applications.”

According to the company, the higher number of sensors implies a greater number of access points, thus increasing the data breach. This means that the communication between the sensor and MCU must be secured to protect against unauthorized wireless access to the vehicle’s central body computer or central processing unit. The NCV-RSL15 offers enhanced security with Arm CryptoCell featuring hardware-based root-of-trust secure boot, many user-accessible hardware-accelerated cryptographic algorithms, and Firmware-over-the-Air (FOTA) capabilities to enable future firmware updates and deployment of security patches. The Onsemi NCV-RSL15 microcontroller is certified by the EEMBC as the industry’s lowest-power, wireless MCU. It will enable vehicle designers to integrate a higher number of sensors in a vehicle without compromising on the security or weight and cost of adding extra wiring to the vehicle.

OnSemi is a semiconductor manufacturer based out of the USA. OnSemi focuses on automotive and industrial end-markets, the company is accelerating change in megatrends such as vehicle electrification and safety, sustainable energy grids, industrial automation, and 5G and cloud infrastructure.
