Mouser ships Microchip microcontroller with Arm TrustZone Security 

Distributor, Mouser Electronics, now ships the SAM L10 and L11 microcontrollers from Microchip Technology. The SAM L11 is claimed to be the first 32-bit microcontroller family to feature Arm TrustZone technology, a programmable environment that provides hardware isolation between certified libraries, IP and application code.

The SAM L10 and L11 microcontrollers are based on a 32-bit Arm Cortex-M23 core and feature picoPower technology, claimed to offer the industry’s lowest power consumption in their class.

The SAM L10 and L11 microcontrollers run at 32MHz and feature up to 64kbytes of flash memory and up to 16kbytes of SRAM. The SAM L10 microcontrollers use a single memory protection unit (MPU) and two debug access levels (DALs), whereas SAM L11 microcontrollers use two MPUs, three DALs, and TrustZone for ARMv8-M.,

The SAM L10 and L11 microcontrollers feature flexible clock distribution optimised for low power and a 32.768kHz crystal oscillator as well as power-on-reset, programmable brown-out detection, an eight-channel direct memory access controller (DMAC), and eight-channel event system for inter-peripheral core-independent operation. Both microcontroller families offer Microchip’s Peripheral Touch Controller (PTC) for capacitive touch capabilities, operational even in the presence of moisture and noise, says Mouser.

For development, Mouser also offers the SAM L10 and L11 Xplained Pro evaluation kits. Each kit is supported by the Atmel Studio 7 integrated development platform, IAR Embedded Workbench, Arm Keil Microcontroller development kit as well as Atmel START, the free online tool to configure peripherals and development software.

The SAM L10 and L11 microcontrollers are suitable for a range of low-power applications, including Internet of Things (IoT), security, automotive, embedded control, medical and other human machine interface (HMI) designs.

Mouser claims to stock the world’s widest selection of the latest semiconductors and electronic components for the newest design projects. Its website is continually updated and offers advanced search methods to help customers quickly locate inventory. also houses data sheets, supplier-specific reference designs, application notes, technical design information, and engineering tools.
