  • Page 26: Crypto Device

    Several of the Atmel security devices require only an I C interface to work, and they share the same packages and pin-outs. SAM L22 Xplained Pro implements a DFN8 footprint for these devices so the user may test the mounted ATECC508A device or solder in other CryptoAuthentication devices.

  • Page 27: Embedded Debugger Implementation

    4.4. Embedded Debugger Implementation SAM L22 Xplained Pro contain an Embedded Debugger (EDBG) that can be used to program and debug the ATSAML22N18A using Serial Wire Debug (SWD). The Embedded Debugger also include a Virtual Com port interface over UART, an Atmel Data Gateway Interface over SPI, and I C and it includes four of the SAM L22 GPIOs.

  • Page 28: Xam Configuration

    4.4.4. XAM Configuration On the SAM L22 Xplained Pro the MCU and the MCU peripherals (e.g. extensions) are powered by its own regulator as shown in the figure below. All other parts of the board, mainly embedded debugger and accompanying Xplained Pro Analog Module (XAM), are powered from a separate regulator. The current to the MCU and peripherals can be measured by connecting them to the XAM output through jumper settings.
