SAM L10 / L11 Series

Industry’s 1st 32-bit MCU with ARM TrustZone for Secured IoT Endpoints


  • Embedded Security with TrustZone
  • Ultra Low Power
  • Enhanced Peripheral Touch Controller (PTC)
  • Hardware touch

Industry’s first ARM® Cortex®-M23, SAM L10 & L11 MCU series, with best-in-class low power consumption and water-tolerant, noise-immune capacitive touch

With the booming growth of Internet of Things (IoT) endpoints, security is sometimes an afterthought for many designers, increasing the risk of exposing intellectual property (IP) and sensitive information. To address the growing need for security, the new SAM L10 and SAM L11 MCU families are now available from Microchip Technology Inc.

  • Best-in-Class Low Power Consumption
    Both SAM L10/L11 MCU families offer the industry’s lowest power consumption. When benchmarked for power consumption the SAM L10 received a ULPMark™ score of 405, which is over 200 percent better performance than nearest competitor certified by EEMBC®, the Embedded Microprocessor Benchmark Consortium.
  • MCU Security Solutions for Authentication and Integrity
    In addition to TrustZone technology, the SAM L11 security features include an on-board 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. It also offers 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 customers 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.
  • Water-Tolerant, Noise-Immune Capacitive Touch
    Both MCU families offer Microchip’s latest generation Peripheral Touch Controller (PTC) for capacitive touch capabilities. It features Driven Shield Plus that provides superior water tolerance and Parallel Acquisition that makes it 4x faster than the previous generation of PTC. Designers can easily add touch interfaces that provide an impressively smooth and efficient user experience 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.
