SAM L10 and L11 Microcontroller Family
Industry’s Lowest Power 32-bit MCUs, First to Offer Chip-Level Security and Arm® TrustZone® Technology
With the increasing growth of 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 L11 MCU family takes an innovative approach to solving these challenges by integrating a wide variety of peripherals, including security features, into the industry's lowest power MCU in its 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 two variant options: SAM L10 and SAM L11 and boast ultra-low power consumption as well as an enhanced Peripheral Touch Controller and advanced analog features. The SAM L11 variant adds integrated hardware security. They both 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.
SAM L11 MCUs integrates chip-level security and ARM® TrustZone® technology to help protect from both physical and remote attacks. They are supported by a comprehensive security solution framework to simplify the implementation of security. IoT nodes driven by a SAM L11 provide strong resistance to remote software attacks thereby increasing the reliability and avoiding downtime of the critical functions of the nodes. The combination of security offered by TrustZone for ARMv8-M and additional hardware-enforced security will help protect from cloning and intellectual property theft.

IoT nodes driven by SAM L11 provide strong resistance to remote software attacks and tampering thereby increasing the node’s reliability and avoiding downtime of critical functions.
Robust Chip-level Security
SAM L11 MCUs were created with security deeply embedded during the silicon design phase. This robust security includes chip-level tamper resistance on 256 Bytes of RAM, Boot ROM design to facilitate secure boot, NIST Compliant TRNG and FIPS compliant AES and secure key storage. It provides physical attack protection with active shield on 256 Bytes of RAM to resist microprobing.
Arm TrustZone Technology
The SAM L11 incorporates Arm TrustZone technology to protect against remote software attacks. Arm TrustZone divides the MCU into trusted and non-trusted zones and provides a hardware isolation to protect keys and sensitive information from non-trusted zones.
SAM L11 MCUs are supported by a comprehensive security solution framework that offers end-to-end solution from secure key provisioning to cloud onboarding to complete device lifecycle management. It is aimed at significantly reducing the developer’s effort while making the applications more secure with faster time to market.
Securely provisioned SAM L11 embeds Trustonic’s Root of Trust (RoT) during the silicon manufacturing to work with Kinibi-M software. The Kinibi-M abstracts away the lower level details of SAM L11’s hardware security to provide a modular approach through a graphical user interface.
Microchip has also partnered with Secure Thingz and Data I/O Corporation to offer secure key provisioning services for SAM L11 customers that have a proven security framework.
Comprehensive Security Solution Framework simplifies integrating security to your embedded design.
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.
|Power Saving Techniques||Benefits|
|SleepWalking||Ability of the peripherals to perform a task without waking up the Central Processing Unit (CPU) from the sleep mode to maintain low power for an extended period|
|Power Domain Gating||Unused power domain can be switched off to reduce the sleep currents even further|
|Dual Performance Levels (PL0 & PL2)||Ability to change the CPU speed on the fly to suit the application activity level. Helps strike a balance between power and performance when in active mode.|
|Event System||Inter-peripheral communication which reduces CPU overhead and saves CPU cycles|
|Integrated, Low-Power Analog |
(Op Amps, ADC, AC, DAC)
Can take inputs from sensors when in sleep
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 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 offers superior noise mitigation techniques and easily passed IEC/EN 61000-4-6 10V rms industry standard conducted immunity noise tests.
