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 are used as a page address. For more details, see the device
(AT30TSE752A/754A/758A) datasheet.
4.3.3 Power LED
The power LED (D101) is connected to the power rail from the extension header. The current
measurement jumper must be closed to enable power to the ATBTLC1000 module.
4.3.4 Reset Switch
The ATBTLC1000 Xplained Pro 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.
Attention: When this switch is used to reset the device, the host MCU loses the status of the
ATBTLC1000 device. It is recommended not to reset the device using this switch when it is
controlled by the host MCU.
4.3.5 32kHz RTC Oscillator
The ATBTLC1000 has a 32.768kHz RTC oscillator that is used for BLE activities involving connection
events. There is also a provision to reconfigure the ATBTLC1000 Xplained Pro board to bypass the
external crystal oscillator with an external signal capable of driving 2pF on the RTC_CLK_P pin of the
ATBTLC1000-MR110CA.

5. Hardware Revision History and Known Issues
5.1 Identifying Product ID and Revision
There are two ways to find the revision and product identifier of the Xplained Pro boards: either through
Atmel Studio or by looking at the sticker on the bottom side of the PCB.
When an Xplained Pro MCU board is connected to a computer with Atmel Studio running, an information
window with the serial number is shown. The first six digits of the serial number contain the product
identifier and revision. Information about connected Xplained Pro extension boards is also shown in the
window.
The same information can be found on the sticker on the bottom side of the PCB. Most kits have stickers
that have the identifier and revision printed 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 data matrix 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 the ATBTLC1000 Xplained Pro is A09-2528.
5.2 Revision 2
Revision 2 is the initially released revision.
The 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 following
image.

6. ATBTLC1000XPRO-ADP Adapter Board
6.1 Kit Overview
The ATBTLC1000XPRO-ADP is an adapter board designed for the ATBTLC1000 Xplained Pro with the
ATBTLC1000-MR110CA Bluetooth module. It is designed to allow direct connection of the ATBTLC1000
Xplained Pro with different Xplained Pro MCU boards for providing UART hardware flow control
functionality.
6.2 Need for the Kit
Due to the non-standard mapping of the UART flow control lines on the extension headers, the
ATBTLC1000 Xplained Pro is incompatible for direct connection with some Xplained Pro platforms. Loose
wire connections are required between the Xplained Pro boards and the ATBTLC1000 Xplained Pro
extension board to support the UART flow control functionality.
The adapter board has been designed to avoid these loose wire connections. It has jumper configurations
to support this functionality across different Xplained Pro MCU boards. The Xplained Pro boards and the
corresponding UART flow control mode supported by the adapter board is shown in the table below.
Table 6-1. Xplained Pro Boards Support

SAM 4S Xplained Pro 4-Wire Mode
SAM G55 Xplained Pro 4-Wire and 6-Wire Mode
6.3 Hardware
The ATBTLC1000XPRO-ADP adapter board has the following headers:
• Female extension header (J100) - 1
• Male extension header (J105) - 1
• 1x3 pin headers (J101, J102, J103, J104, J106, J107) - 6
ATBTLC1000-XPRO

© 2019 Microchip Technology Inc. User Guide DS50002847A-page 15

• 2x5 pin headers (J108, J109) - 2
The adapter board can be connected to several Xplained Pro MCU boards using a female extension
header. The male extension header is used to connect it to the ATBTLC1000 Xplained Pro.
The jumpers on the pin headers have to be placed based on the Xplained Pro board used and the UART
Flow Control mode of the ATBTLC1000 Xplained Pro (6-Wire mode or 4-Wire mode), as shown in the
following table.

Note:
1. Chip Enable is available on Pin 4 of revised ATBTLC1000 XPRO boards (see 5.2 Revision 2).
2. Primary UART is used only for enabling the hardware flow control on the secondary UART. After
enabling the hardware flow control on the secondary UART, all the communications between the
host MCU and the ATBTLC1000 happen through the secondary UART.

Microchip Devices Code Protection Feature
Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the
market today, when used in the intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of
these methods, to our knowledge, require using the Microchip products in a manner outside the
operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is
engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
