With the booming growth of Internet of Things (IoT) endpoints, security is sometimes an afterthought for many designers, increasing the risk of exposing intellectual property (IP) and sensitive information. To address the growing need for security, the new SAM L10 and SAM L11 MCU families are now available from Microchip Technology Inc.
The new MCU families are based on the Arm® Cortex®-M23 core, with the SAM L11 featuring Arm TrustZone® for Armv8-M, a programmable environment that provides hardware isolation between certified libraries, IP and application code. Microchip enables robust security by including chip-level tamper resistance, secure boot and secure key storage that, when combined with TrustZone technology, protects customer applications from both remote and physical attacks.
Both MCU families offer the industry’s lowest power consumption, as well as have capacitive touch capability with best-in-class water tolerance and noise immunity. When benchmarked for power consumption the SAM L10 received a ULPMark™ score of 405, which is over 200 percent better performance than nearest competitor certified by EEMBC®, the Embedded Microprocessor Benchmark Consortium. Microchip uses proprietary picoPower® technology to provide industry-leading low power consumption in active and all sleep modes.
