SAM L10 and SAM L11 Microcontrollers (MCUs)

Ultra Low-Power SAM L10 and SAM L11 Microcontrollers

With the increasing growth of Internet of Things (IoT) end points and, consequently, the increased frequency of security breaches, designers are looking for MCUs that can help reduce power consumption while adding robust security. The SAM L10 and SAM L11 families of MCUs take an innovative approach to solving these challenges by integrating a wide variety of peripherals, including security features, into the industry's lowest-power MCUs in their class. This allows you to develop secured applications without the battery constraints of less power-efficient MCUs. These MCUs run at 32 MHz with memory configuration of up to 64 KB Flash and 16 KB SRAM. They come in three variant options, SAM L10, SAM L11 and SAM L11-KPH, and boast ultra-low power consumption as well as an enhanced Peripheral Touch Controller and advanced analog features. Both families of MCUs come in 24- and 32-pin package options and are targeted for use in IoT and security, low-power, capacitive touch and general-purpose embedded control applications.

The SAM L11 and SAM L11-KPH add integrated hardware security. The SAM L11-KPH adds a factory-provisioned root of trust key to provide the MCU with a secure identity that can be used for developing secure IoT applications. The SAM L11 and SAML11-KPH MCUs are supported by a comprehensive security ecosystem that includes Trustonic’s Kinibi-M™ solution and Secure Thingz’ Secure Deploy™ architecture.

SAM L11 MCUs are PSA Certified™ Level 1, which assures that the best embedded security practices have been implemented for IoT products.

Robust Security

SAM L11 MCUs integrate hardware-based security and Arm^® TrustZone^® technology to help protect devices from remote attacks. To reduce your development effort and speed your time to market, they are supported by a comprehensive security solution framework that delivers an end-to-end solution, from secure key provisioning, to cloud onboarding to complete lifecycle management. IoT nodes driven by a SAM L11 provide strong resistance to remote software attacks, which increase the nodes’ reliability and avoids downtime of their critical functions. The combination of security offered by Arm TrustZone for ARMv8-M and additional hardware-enforced security will help protect your devices from cloning and intellectual property theft. The SAML11-KPH also includes an immutable identity and Kinibi-M Trusted Execution Environment (TEE) for secure application development.

Robust Chip-Level Security and Arm TrustZone Technology

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.

Kinibi-M: Secure Application Development Software Framework by Trustonic

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.

Capacitive Touch: Superior Water Tolerance, Noise Immunity and Responsiveness

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.
