World-Class, Award-Winning SAM L10 and SAM L11 Microcontroller Family

Key provisioning solutions are available for the SAM L11 and SAM L11-KPH series of devices.

IoT nodes driven by a SAM L11 MCU provide strong resistance to remote software attacks and tampering, which increases the nodes’ reliability and avoids downtime of their critical functions.

Robust Chip-Level Security

SAM L11 MCUs were created with deeply embedded security during their silicon design phase. Robust security features include chip-level tamper resistance, active shield and scrambling on 256 bytes of TrustRAM, Boot ROM designed to facilitate secure boot, NIST-compliant TRNG, FIPS-compliant AES, scrambling on data Flash, and Arm TrustZone technology to enable hardware secure partition to facilitate IP protection, code isolation and protection from remote attacks. The active shield on 256 bytes of TrustRAM protects against physical attacks and resists microprobing attacks.   

Arm TrustZone Technology

The SAM L11 incorporates Arm TrustZone technology to protect against remote software attacks. It divides the MCU into trusted and non-trusted zones and provides hardware isolation to protect keys and sensitive information from non-trusted zones.

SAM L11 MCUs are supported by Kinibi-M, a comprehensive security solution framework that offers an end-to-end solution, from secure key provisioning to cloud onboarding to complete device lifecycle management. It is aimed at making your applications more secure while significantly reducing your development effort and speeding your time to market.

Kinibi-M is a Trusted Execution Environment (TEE) that is designed to integrate all the SAM L11’s security features and provide a modular and easy-to-use secure application development environment. It covers most requirements, including supply chain protection, automatic cloud enrollment, device attestation and provenance and software isolation and IP protection.

Ready to Get Started with the SAM L11 and Kinibi-M?

Jump-start your secure application development with the SAML11 Xplained Pro Evaluation Kit (DM320205) and Kinibi-M. You can also download the Trustonic IoT Developer Kit, which includes a free developer SDK pack, software, demos and documentation to help you get started with building your first secure IoT solution.

The SAM L11 family is fully integrated with Secure Thingz’ Secure Deploy architecture, which can be used to provision SAM L11 MCUs at secure external programming centers.  The Secure Deploy architecture has been designed to enhance and simplify security implementations and enable the protection of critical Intellectual Property (IP) throughout your product’s creation, manufacture and management. It features:

• Simple management of critical IP within the development process
• Secure key management targeted for development, manufacturing and applications
• Elimination of over-production and counterfeiting through constrained device programming

For more information about Secure Deploy and additional resources to help you get started  with programming and provisioning the SAM L11 MCU, Please visit the Microchip SAM L11 page on the Secure Thingz website.

Devices with picoPower technology, such as the SAM L10 and SAM L11 MCUs, are designed for the lowest possible power consumption from transistor design and process geometry, sleep modes, flexible clocking options, on-the-fly user selectable performance levels, event system to SleepWalking peripherals. This technology provides flexible power-saving techniques that enable the creation of designs with longer battery lives and lower total system costs.

Add superior capacitive touch interfaces to your application with the SAM L10/11 family. These MCUs offer an enhanced Peripheral Touch Controller (PTC) with Driven Shield Plus and Parallel Acquisition allowing you to differentiate your designs with exceptional touch-based capabilities.

Driven Shield Plus

Driven Shield Plus offers best in class water tolerance and noise immunity. It enables touch for products in dew, sweat, rain and even running water. It can also be designed in to products that are IP-68 rated. It supports touch surfaces with pinch and zoom capabilities in the presence of water.

Parallel Acquisition

Parallel acquisition improves the responsiveness of the touch interface by acquiring multiple touch sensors simultaneously as opposed to the traditional way of acquiring them sequentially. This makes the PTC on SAM L10/11, four times faster than the previous generation of PTCs. It also filters out noise and significantly improves responsiveness of high button count touch interfaces.

The PTC on SAM L10/11 MCUs offers superior noise mitigation techniques and easily passed IEC/EN 61000-4-6 10V rms industry standard conducted immunity noise tests.

The SAM L10 and SAM L11 Xplained Pro Evaluation Kits are available to kick-start your development. These are fully supported with security, low-power and touch demos to accelerate your development so you can get to market faster.

All SAM L10/L11 MCUs are supported by MPLAB X and Microchip Studio Integrated Development Environments (IDEs), IAR Embedded Workbench, Arm Keil^® MDK as well as MPLAB Harmony v3 and Atmel START, which are free tools you can use to configure peripherals and software to accelerate your development. Atmel START also supports Arm TrustZone technology to configure and deploy secure applications. A power debugger and data analyzer tool is available to monitor and analyze power consumption in real-time and fine tune the consumption numbers on the fly to meet application needs. Our QTouch^® Modular Library, 2D Touch Surface Library and QTouch Configurator are also available to simplify touch development.
