Temperature Sensor
The SAM B11ZR Xplained Pro has an on-board temperature sensor AT30TSE758A, powered by the
VCC_TARGET_P3V3 of the board. The temperature sensor is I²C controlled and is available on the
address 0x48 (7-bit MSB address).
AT30TSE758A also has a serial EEPROM accessible through I

Crypto Authentication Device
The SAM B11ZR Xplained Pro has a Crypto Authentication Device (ATECC508A) connected to the I
bus. The table below shows all the connections between the ATECC508A and ATSAMB11ZR-210CA
module.

Embedded Debugger Implementation
SAM B11ZR Xplained Pro contains an Embedded Debugger (EDBG) that can be used to program and
debug the ATSAMB11ZR using Serial Wire Debug (SWD). The Embedded Debugger also includes a
Virtual Com port interface over UART, a Data Gateway Interface (DGI) over SPI, and I
includes four of the SAM B11ZR GPIOs. The kit also includes a XAM extension processor to the
Embedded Debugger for on-board current measurement. Atmel Studio can be used as a front-end for the
Embedded Debugger.
4.3.1
Serial Wire Debug
The Serial Wire Debug (SWD) uses two pins to communicate with the target. For further information on
how to use the programming and debugging capabilities of the EDBG, see

Virtual COM Port
The Embedded Debugger acts as a Virtual Com Port gateway by using one of the ATSAMB11ZR UARTs.
