1 Introduction
The AS6200 and AS6200C adapter boards are a small PCB allowing a simple and quick evaluation
of the AS6200 and AS6200C digital temperature sensors without the need to design a custom PCB.
This small form factor board is fully assembled with the AS6200/C temperature sensor and its
necessary external components.

2 Getting Started
The AS6200/C adapter board is ideal for rapid setup of a digital temperature sensor. To get started
connect the board to your microcontroller configuration as described in Figure 3: I²C connection.
Add a command in your source code to request two bytes from the selected I²C address. Finally
convert the returned data as described in chapter 4.2 Temperature Register to get the actual
temperature value.
3 Hardware Description
The P1 connector does provide all relevant signals which can be easily wired to a microcontroller
and power supplied with a voltage of 1.8 to 3.6V

R1, R2 and R3 are pull-up resistors for the I²C interface and the Alert pin.
Depending on the application, it is recommended to either populate the decoupling capacitor C1 or
C2.

3.2 AS6200/C Configuration
With the address selector, it is possible to choose the I²C address of the device. The included
jumper is an easy way of setting the I²C address of the sensor. The address selector must not be
left open.

3.3 Power Supply and Connections
The PCB has to be connected to an external microcontroller. P1 is populated with a 1x5 pin header
and is required for power supply as well as I²C communication. In addition to that it can be used to
monitor the interrupt status via pin 5 (IRQ).

4 Software Description
The AS6200/C has 4 data registers. With the use of the index register, it is possible to address the
specific data register. When powered up the address register is set to 0x0.
For additional configuration settings the Config register (0x1) has to be addressed. Please refer the
data sheet for details.

Table 6: Temperature Register
The temperature register contains the digitally converted temperature value. It
consists of 2 byte and can be converted according to the following formula:
Positive values= |Value| / LSB
Negative values= Complement( |Value| / LSB ) + 1
Example +75°C
75°𝐶/0.0625°𝐶 = 1200 = 𝐵𝑖𝑛𝑎𝑟𝑦 0100 1011 0000 = 𝐻𝑒𝑥 4𝐵0
Example -40°C
|−40°𝐶|/0.0625°𝐶 + 1 = 640 + 1 = 𝐵𝑖𝑛𝑎𝑟𝑦 0010 1000 0000 + 1 = 1101 0111 1111 + 1 =
