First 32-Bit Microcontrollers to Support Arm TrustZone

The SAM L10 and L11 microcontroller family is the industry’s first 32-bit MCU family featuring, robust chip-level security and Arm® TrustZone® Technology. Available in two variant option, SAM L10 and SAM L11, these MCUs boast the industry’s lowest power consumption in their class, enhanced Peripheral Touch Controller and advanced analog features. The SAM L11 variant adds integrated hardware security and is supported by the Comprehensive Security Solution Framework which includes Trustonic’s Kinibi-M and Secure Thingz key provisioning services. Available in 24- and 32-pin package options, these MCUs take an innovative approach to solving the challenges faced by the designers of IoT, security, low-power, capacitive touch and general-purpose embedded control applications.
