They also feature Microchip’s latest-generation Peripheral Touch Controller (PTC), allowing designers to incorporate capacitive touch interfaces into their applications that offer best-in-class water tolerance and high noise immunity. Four times faster than the previous generation of PTC, it provides highly-responsive and accurate touch sensing and is supportedby theQTouchConfigurator and Modular Library, making it simple for designers to add elegant touch interfaces to applications that provide an impressively smooth and efficient user experience, even in the presence of moisture and noise, while maintaining low power consumption. The touch interface makes the devices ideal for a myriad of automotive, appliance, medical and consumer Human Machine Interface (HMI) applications.

as well as an enhanced Peripheral Touch Controller and advanced analogue features, with the SAM L11 variant adding integrated hardware security. They both come in 24- and 32-pin package options and are targeted for use across IoT and security, low power, capacitive touch and general purpose embedded control applications. The SAM L11 features Arm TrustZone technology, a programmable environment that simplifies the implementation of security and provides hardware isolation between certified libraries, IP and application code. Microchip further enhances robust security by including chip- level tamper resistance, secure boot and secure key storage which, when combined with TrustZone technology, provides a comprehensive security framework that protects customer applications from both physical and remote attacks. IoT nodes driven by a SAM L11 provide strong resistance

to remote software attacks, thereby increasing reliability and avoiding downtime of the critical functions of the nodes. The chip-level tamper resistance helps protect nodes from cloning and IP theft. Both MCU families offer the industry’s lowest power consumption, allowing developers to create extremely power-efficient designs. When benchmarked for power consumption, the SAM L10 received a ULPMark score of 405, 200% better than its nearest EEMBC-certified competitor. Built with proprietary picoPower technology to provide flexible power saving modes across all active and sleep modes, the MCUs are supported with power debugging and data visualiser tools to monitor and analyse power consumption in real time. This helps developers to rapidly optimise their system design for lower power consumption, with significant improvements in battery life.
