Microchip releases first 32-bit MCUs to feature robust, chip-level security and Arm TrustZone® technology

Microchip announces the new SAM L10 and SAM L11 families of 32-bit microcontrollers (MCUs) which address the growing need for security in Internet of Things (IoT) endpoints by protecting against the increasing the risk of exposing intellectual property (IP) and sensitive information.

The new 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 robust security by including chip-level tamper resistance, secure boot and secure key storage which, when combined with TrustZone technology, protects customer applications from both remote and physical attacks.

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.

The SAM L10 (DM320204) and SAM L11 (DM320205) Xplained Pro Evaluation Kits, priced at $58.00 each, are available to kick-start development. All SAM L10/L11 MCUs are supported by the Atmel Studio 7 Integrated Development Environment (IDE), IAR Embedded Workbench, Arm Keil® MDK as well as Atmel START, a free online tool to configure peripherals and software for accelerated development. START also supports TrustZone technology for configuring and deploying secure applications. A power debugger and data analyser tool is available to monitor and analyse power consumption in real-time and fine-tune the consumption numbers on-the-fly to meet application needs. Microchip’s QTouch® Modular Library, 2D Touch Surface Library and QTouch Configurator are also available to simplify touch development.

 

The SAM L10 and SAM L11 devices are available today in a variety of pin counts and package options in volume production quantities.
