Microchip Technology SAM L22 Xplained Pro Evaluation Kit

Microchip Technology SAM L22 Xplained Pro Evaluation Kit (ATSAML22-XPRO-B) is a demonstration and development platform for the SAM L22 Arm® Cortex®-M0+ Microcontroller. The ultra-low-power SAM L22 MCU features sophisticated power management technologies, a segment LCD controller, tamper detection, smart card interface, Full Speed USB, Event System and Sleepwalking, 12-bit analog, AES, and capacitive touch sensing. The SAM L22 combines ultra-low power with Flash and SRAM that are large enough to run both the application and wireless stacks, making it ideal for a number of applications including the Internet of Things (IoT), consumer, industrial, medical, and battery-powered devices.  

The Microchip Technology SAM L22 Xplained Pro Evaluation Kit includes an on-board Embedded Debugger and no external tools are necessary to program or debug the ATSAML22N18A. The Evaluation Kit also includes the TSLCD1 Xplained Pro Extension Board for Touch and Segment LCD applications  and the ECC508 Crypto Authentication device to enable advanced elliptic curve cryptography (ECC). It is an ideal development platform for secure IoT nodes, wearables, medical & general purpose battery-powered applications.
