SAM L10/11 Family of Arm® Cortex®-M23 MCUs

Release on : Jun 28, 2018

The SAM L10 and SAM L11 MCU families from Microchip Technology are based on the Arm Cortex-M23 core, with the SAM L11 featuring Arm TrustZone for Armv8-M. This is a programmable environment that provides hardware isolation between certified libraries, IP, and application code. Microchip enables robust security by including chip-level tamper resistance, secure boot, and secure key storage that, when combined with TrustZone technology, protects customer applications from both remote and physical attacks. Both MCU families offer the industry’s lowest power consumption, as well as having capacitive touch capability with best-in-class water tolerance and noise immunity. 

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 certified by EEMBC®, the embedded microprocessor benchmark consortium. Microchip uses proprietary picoPower® technology to provide industry-leading low power consumption in active and all sleep modes. 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. Both the SAM L10 and SAM L11 families offer Microchip’s latest generation peripheral touch controller (PTC) for capacitive touch capabilities. 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.
