2. Getting Started
2.1. Xplained Pro Quick Start
Three steps to start exploring the Atmel Xplained Pro platform:
1. Download Atmel Studio.
2. Launch Atmel Studio.
3. Connect ATBTLC1000 Xplained Pro to an Xplained Pro MCU board and connect a USB cable to
the DEBUG USB port on the Xplained Pro MCU board.
When the Xplained Pro MCU kit is connected to your computer for the first time, the operating system will
perform a driver software installation. The driver file supports both 32- and 64-bit versions of Microsoft
®
Windows® XP, Windows Vista®, Windows 7, and Windows 8.
Once the Xplained Pro MCU board is powered the green power LED will be lit and Atmel Studio will auto
detect which Xplained Pro MCU- and extension board(s) are connected. Atmel Studio will present
relevant information like datasheets and kit documentation. The kit landing page in Atmel Studio also has
the option to launch Atmel Software Framework (ASF) example applications for the kit. The target device
is programmed and debugged by the on-board Embedded Debugger and therefore no external
programmer or debugger tool is needed.

4. Xplained Pro
Xplained Pro is an evaluation platform that provides the full Atmel microcontroller experience. The
platform consists of a series of Microcontroller (MCU) boards and extension boards, which are integrated
with Atmel Studio, have Atmel Software Framework (ASF) drivers and demo code, support data
streaming, and more. Xplained Pro MCU boards support a wide range of Xplained Pro extension boards,
which are connected through a set of standardized headers and connectors. Each extension board has
an identification (ID) chip to uniquely identify which boards are connected to an Xplained Pro MCU board.
This information is used to present relevant user guides, application notes, datasheets, and example
code through Atmel Studio.
4.1. Hardware Identification System
All Xplained Pro compatible extension boards have an Atmel ATSHA204 CryptoAuthentication™ chip
mounted. This chip contains information that identifies the extension with its name and some extra data.
When an Xplained Pro extension is connected to an Xplained Pro MCU board the information is read and
sent to Atmel Studio. The Atmel Kits extension, installed with Atmel Studio, will give relevant information,
code examples, and links to relevant documents. Table 4-1 Xplained Pro ID Chip Content on page 7
shows the data fields stored in the ID chip with example content.

4.2. Xplained Pro Headers and Connectors
4.2.1. Xplained Pro Standard Extension Header
All Xplained Pro kits have one or more dual row, 20-pin, 100mil extension header. Xplained Pro MCU
boards have male headers, while Xplained Pro extensions have their female counterparts. Note that all
pins are not always connected. All connected pins follow the defined pin-out description in Table 4-2
Xplained Pro Standard Extension Header on page 8.
The extension headers can be used to connect a variety of Xplained Pro extensions to Xplained Pro MCU
boards or to access the pins of the target MCU on Xplained Pro MCU boards directly.

ATBTLC1000 Xplained Pro can be connected to several Xplained Pro MCU boards and manually
connected to other hardware. Xplained Pro MCU board(s) that does not have 3.3V as it's primary target
voltage will read all ID devices on connected extensions to check if they support the target voltage before
enabling it to the extension headers. The table below shows the static content written in the ID chip.

5.2.2. Current Measurement Header
Current Measurement header J101 can be used to measure the current consumed by the ATBTLC1000
module using an ammeter. The two 0Ω resistors R112 and R113 can be removed to measure the current
consumed by individual power rails VDDIO and VBAT respectively by soldering in wires for an ammeter.
5.2.3. Debug Connectors
Debug I2C (J104) and Extension port (J105) are not mounted on the board. Extension port J105 can be
configured as Debug UART or as SPI to connect to external sensors. Refer to the ATBTLC1000MR110CA datasheet for reference.

5.3. Peripherals
5.3.1. External Flash
ATBTLC1000 Xplained Pro provides a footprint for an external flash (U103), the design is tested with an
ISSI IS25LD020-JNLE 2Mb flash. By default the flash is connected to the SPI Master/Slave interface of
the ATBTLC1000 module, which is also connected to the Xplained Pro extension header.
The SPI Flash master interface of the ATBTLC1000 can also be used to control the external flash by
reconfiguring the jumper straps (J109-J112) as below.
External flash Configuration 1: ATBTLC1000 SPI0 peripheral connected (default)
External flash Configuration 2: ATBTLC1000 SPI flash peripheral connected
Refer to Design Documentation and the ATBTLC1000-MR110CA datasheet for further reference.

5.3.2. Temperature Sensor
The ATBTLC1000 Xplained Pro extension board features an Atmel AT30TSE758 temperature sensor with
an 8kb serial EEPROM inside. The sensor includes programmable high and low temperature alarms,
user-selectable temperature resolution up to 12 bits, and an I2C/SMBus™ compatible serial interface.

The temperature sensor has two I2C addresses; one for the temperature sensor and one for the
EEPROM. The addresses are "0b1001 A2 A1 A0" for the temperature sensor and "0b1010 A2 A1 A0" for
the EEPROM. The address selection lines (A2, A1, and A0) of the temperature sensor are shorted to
GND, which makes the default addresses 0b1001000 and 0b1010000. When communicating with the
EEPROM parts of the TWI address is used as a page address. For more details, see the device
(AT30TSE752A/754A/758A) datasheet.
5.3.3. Power LED
Power LED (D101) is connected to the power rail from the extension header. Current measurement
jumper has to be closed to enable power to the ATBTLC1000 module.
5.3.4. Reset Switch
ATBTLC1000-XPRO contains footprint of switch (SW100) along with resistor R111 and capacitor C107
that can be mounted to reset the ATBTLC1000. The switch is connected to the CHIP_EN pin of the
ATBTLC1000, which is pulled up by default.

5.3.5. 32kHz RTC Oscillator
The ATBTLC1000 has a 32.768kHz RTC oscillator that is used for BLE activities involving connection
events. There is also provision to reconfigure the ATBTLC1000 Xplained Pro board to bypass external
crystal oscillator with an external signal capable of driving 2pF on the RTC_CLK_P pin of the
ATBTLC1000-MR110CA.

6. Hardware Revision History and Known Issues
6.1. Identifying Product ID and Revision
The revision and product identifier of Xplained Pro boards can be found in two ways; either through Atmel
Studio or by looking at the sticker on the bottom side of the PCB.
By connecting an Xplained Pro MCU board to a computer with Atmel Studio running, an information
window will pop up. The first six digits of the serial number, which is listed under kit details, contain the
product identifier and revision. Information about connected Xplained Pro extension boards will also
appear in the Atmel Kit's window.
The same information can be found on the sticker on the bottom side of the PCB. Most kits will print the
identifier and revision in plain text as A09-nnnn\rr, where nnnn is the identifier and rr is the revision.
Boards with limited space have a sticker with only a QR-code, which contains a serial number string.
The serial number string has the following format:
"nnnnrrssssssssss"
n = product identifier
r = revision
s = serial number
The product identifier for ATBTLC1000 Xplained Pro is A09-2528.
6.2. Revision 2
Revision 2 is the initially released revision.
ATBTLC1000 Xplained Pro revision 2 is partially incompatible with SAM L21 Xplained Pro extension
header EXT1, pin 10 (Chip Enable) is shared with the user button SW0 on the SAM L21 Xplained Pro. A
workaround for the incompatibility is to modify the kit by cutting a track in the PCB from pin 10, and
soldering a wire from a test point to pin 4, of the Xplained Pro extension header as shown in the image
below.
