1.1 Introduction
The evaluation board of the temperature sensor provides an opportunity to verify the sensor
performance and develop a prototype using an external processor e.g. Amber Pi design
kit (Part No: 2609017281001). It can be directly plugged to Amber Pi design kit using the
mounted I2C interface pins. It can also be placed on a bread board using through hole pin
header connections.
The temperature sensor IC (Part No: 2521020222501) is a 16-bit compact silicon based digital temperate sensor with an I2C interface. The sensor features programmable temperature
thresholds and interrupt functionality.

2 Functional description
The temperature sensor evaluation board supports the standard I2C communication interface.
• A positive supply voltage is applied to the sensor through VDD pin.
• The 7-bit I2C slave address of the temperature sensor is either 0111000b or 0111111b
based on the SAO pin connection.
By default the 7-bit slave address of the temperature sensor on the evaluation
board is 0111000b (0x38). i.e. SAO pin of the sensor is connected to VDD
using 0Ω resistor ADDR.
The 7-bit slave address of the temperature sensor can be changed to
0111111b (0x3F) by removing 0Ω resistor ADDR from ’1’ part and mounting
it on the ’0’ part of the evaluation board. i.e. SAO pin is connected to GND
using 0Ω resistor ADDR.
