Designing Systems with Multiprotocol Connectivity The SAM L11 family offers integrated hardware security, featuring Arm TrustZone for Armv8-M, a programmable environment that provides hardware isolation between certified libraries, IP and application code. This solution enables robust security by including chip-level tamper resistance, secure boot, and secure key storage that, when combined with TrustZone technology, is designed to shield your IoT application from both physical and remote attacks. In addition to TrustZone technology, the SAM L11 security features include an onboard cryptographic module supporting Advanced Encryption Standard (AES), Galois Counter Mode (GCM) and Secure Hash Algorithm (SHA). The secure boot and secure key storage with tamper detection capabilities establish a hardware root of trust. The SAM L11 also offers a secure bootloader for secure firmware upgrades. Microchip has partnered with Trustonic, a member of Microchip's Security Design Partner Program, to offer a comprehensive security solution framework that simplifies implementation of security and enables you to introduce end products faster. Microchip has also partnered with Secure Thingz and Data I/O Corporation to offer secure provisioning services for SAM L11 customers that have a proven security framework. Microchip has created a video to describe how the SAM L11's security features, example use cases, and other resources make it easy to implement security in your design. A second video provides you with an overview of how the SAM L11 Trusted Execution Environment can be used to implement a secure temperature sensor application while counteracting malware and physical attacks. Industry's Lowest Power Consumption Optimizing your system design for lower power consumption is especially important when you are creating battery-powered devices. As the lowest-power MCUs in their class, the SAM L10 and SAM L11 are built with Microchip's proprietary picoPower technology, as well as other power-saving features, to provide low power consumption in active and all sleep modes. When benchmarked for power consumption, the SAM L10 received a ULPMark score of 405, which is over 200 percent better performance than the nearest competitor as certified by the Embedded Microprocessor Benchmark Consortium (EEMBC). Superior Capacitive Touch Adding an exceptional touch-based user interface to your design is easy with the SAM L10 and SAM L11. Both MCU families feature an enhanced Peripheral Touch Controller (PTC) offering best-in-class water tolerance and high noise immunity. This PTC is four times faster than the previous generation and provides highly responsive and accurate touch sensing. The PTC enables you to implement a low-power touch interface that provides an impressively smooth and efficient user experience, even in the presence of moisture and noise. The PTC makes the SAM L10 and SAM L11 well suited for use in a myriad of automotive, appliance, medical, and consumer Human Machine Interface (HMI) applications. Watch this video to get a quick overview of the PTC implementing the Driven Shield Plus feature for creating a water-tolerant touch application: | 10 | s s s
