June 25, 2018 —To address the growing need for security, the SAM L10 and SAM L11 MCU families are now available from Microchip Technology
The MCU families are based on the Arm Cortex-M23 core, with the SAM L11 featuring Arm TrustZone for Armv8-M, a programmable environment that provides hardware isolation between certified libraries, IP and application code. Microchip enables security by including chip-level tamper resistance, secure boot and secure key storage that, when combined with TrustZone technology, is designed to protect customer applications from both remote and physical attacks.
Both MCU families have capacitive touch capability with water tolerance and noise immunity. When benchmarked for power consumption the SAM L10 received a ULPMark score of 405, certified by EEMBC, the Embedded Microprocessor Benchmark Consortium.
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 boot and 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. Microchip has also partnered with Secure Thingz and Data I/O Corporation to offer secure provisioning services for SAM L11 customers.
Both MCU families offer Microchip’s Peripheral Touch Controller (PTC) for capacitive touch capabilities. The touch interface makes the devices suitable for a myriad of automotive, appliance, medical and consumer Human Machine Interface (HMI) applications.
