TheSAM L22 Xplained Pro Development Board uses an ATSAML22N18A MCU. The board includes theTouch SLCD1 Xplained Pro Extension Kit (179 segments) for touch and segment LCD applications and an ECC508 Crypto Authentication device to enable advanced elliptic curve cryptography (ECC). It is an ideal development platform for secure IoT nodes, wearables, medical, and general-purpose battery-powered applications.
This board can also be used with theSegment LCD1 Xplained Pro Extension Kit (96 segments).
This board has an on-board programmer/debugger. No external programmer/debugger (e.g.,SAM-ICE™) is required.

Atmel START example projects for this board
As of March 2018, the following example projects are available in Atmel START. To find all currently available example projects related to this board, go to theAtmel START homepage, click onBROWSE EXAMPLES, and select this board from the drop-down window.
| Project Name | Description |
|---|---|
| ADP HELLO WORLD DEMO | The example sends "Hello, World!" to the terminal in Data Visualizer using SPI Master driver. |
| CALENDAR DEMO | This example shows the use of the Calendar driver and alarms to blink LED0 every 10 seconds. |
| EDBG UART | The example application uses the Asynchronous USART driver to communicate with the console via EDBG Virtual COM Port. The example echoes received data back to the console. |
| LED FLASHER | This example periodically toggles the onboard LED marked as LED0. |
| LED SWITCHER | This example toggles the onboard LED marked as LED0 every time the buttonSW0 is pressed. |
| PWM EXAMPLE | This example periodically reads data from the light sensor using the ADC driver and uses read data to control PWM duty cycle. |
| RTOS DEMO | After start-up, the application blinks the LED continuously. By inputting the character from the EDBG Virtual COM Port the LED changes its blinking state. |
| MutualCap Example with QT1Extension | This example demonstrates the basic touch application where the touch sensors are measured and the touch status is indicated using LED on the QT1 extension board. The touch library parameters are also displayed in the data visualizer software when the hardware kit is connected through EDBG/MEDBG virtual com port. |
| Selfcap Example with onboard sensor | This example demonstrates the basic touch application where the touch sensors are measured and the touch status is indicated using an LED with an onboard sensor. The touch library parameters are also displayed in the data visualizer software when the hardware kit is connected through EDBG/MEDBG virtual com port. |
| SEGMENT LCD EXAMPLE | The example application uses the Synchronous SLCD driver to drive segments of the TSLCD1 Xplained pro board. It turns on, blinks and animates segments. It also draws 7-segment and 14-segment characters. |
| USB CDC ECHO | This demo behaves like a virtual COM port based on USD device CDC. It echoes back bytes received from the console. |
| USB COMPOSITE DEVICE | This demo behaves like a composite device, which is composed of CDC ACM, HID Mouse, and HID Keyboard. The virtual com echoes back bytes received from the console. PressingButton1 down will make the mouse move leftward and pressingButton3 down makes it move rightward.Button2 is used as Caps Lock key for this application. |
| USB HID GENERIC | This demo behaves like an HID generic device to communicate with the Atmel PC Tool (AVR153 – USB PC Drivers Based on Generic HID). |
| USB HID KEYBOARD | This demo behaves like a keyboard based on USB device HID. TheButton1 is used asCtrl,Button2 used asAlt, andButton3 used asDel on OLED1 Xplained Board. |
| USB HID MOUSE | This demo behaves like a mouse based on USB device HID. Mouse pointer moves based on the button which is pressed down on the OLED1 Xplained Board.Button1 is to the left andButton3 is to the right. |
| USB MSC DEVICE | This demo behaves as a removable disk, which is 22 Kb used by internal RAM. |
