Item Comment 1 AS6200-EK-AB Eval kit adapter board Table 1: Kit Content ams Eval Kit Manual [v1-00] 2016-Jun-01 Page 3 Document Feedback AS6200 Adapter Board 2 Getting Started The AS6200 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 Pin Symbol Description Info 1 SCL I²C clock Use R1 if pull-up is required 2 SDA I²C data Use R2 if pull-up is required 3 GND Ground 4 VDD Power supply 1,8 β 3,6 V 5 IRQ Digital output pin Alert interrupt output Table 2 Adapter board pin-out 3.1 Hardware Architecture P1 connector Address selector AS6200 0 Figure 2: AS6200 adapter board 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. ams Eval Kit Manual [v1-00] 2016-Jun-01 Page 4 Document Feedback AS6200 Adapter Board 3.2 AS6200 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. Address Selector Device Address GND 100 1000 0x48 VDD 100 1001 0x49 Table 3: I²C address 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).

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. 0x0 TVAL (Read Only) 0x1 CONFIG (Read/Write) 0x2 SCLK TLOW (Read/Write) 0x3 Serial Interface SDA THIGH (Read/Write) INDEX (Read/Write) For additional configuration settings the Config register (0x1) has to be addressed. Please refer the data sheet for details. Address Symbol 0x0 0x1 TVAL Register Description Temperature Register Contains the temperature value CONFIG Configuration Register Configuration settings of the temperature sensor 0x2 TLOW TLOW Register Low temperature threshold value 0x3 THIGH THIGH Register High temperature threshold value Table 4: Configuration Register 4.1 Index Register The index register contains 8 bit, but only D0 and D1 are used.
