Onsemi extends Bluetooth LE MCU Family for automotive wireless applications
Along with the number of sensors in vehicles grows the weight and complexity of cabling – and the number of possible attack vendors. In response to these challenges, smart power chip company onsemi has developed an ultra-low power automotive-grade wireless microcontroller with Bluetooth Low Energy connectivity.
While the lists of sensors and general functionality in Tire Monitoring Systems (TMS) and other sensing applications continue to grow, the power consumption budget has not increased. At the same time, some applications now have a requirement for a 10-year battery lifetime. Onsemi’s new NCV-RSL15 is certified by the EEMBC as the industry’s lowest power secure, wireless microcontroller, featuring the proprietary smart sense power mode, it is designed to use as little power as possible. Being able to conserve more battery directly equates to increased product longevity.
“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.”
As the number of access points increases, so does the number of potential attack vectors that must be secured to protect against unauthorized wireless access to the vehicle’s central body computer or central processing unit. The NCV-RSL15 offers the latest in embedded 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.
