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.

Table 1: Ordering information
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.

2.1.2 Through hole connection
Through hole pin header connection gives direct access to each sensor pin. SDA, SCL and
INT pins must be connected to VDD via pull-up resistors. SAO pin connection to either VDD
or GND is also necessary in order to define an I2C slave address.

4 Important notes
The following conditions apply to all goods within the sensors product range of Würth Elektronik eiSos GmbH & Co. KG:
4.1 General customer responsibility
Some goods within the product range of Würth Elektronik eiSos GmbH & Co. KG contain
statements regarding general suitability for certain application areas. These statements
about suitability are based on our knowledge and experience of typical requirements concerning the areas, serve as general guidance and cannot be estimated as binding statements
about the suitability for a customer application. The responsibility for the applicability and use
in a particular customer design is always solely within the authority of the customer. Due to
this fact, it is up to the customer to evaluate, where appropriate to investigate and to decide
whether the device with the specific product characteristics described in the product specification is valid and suitable for the respective customer application or not. Accordingly, the
customer is cautioned to verify that the documentation is current before placing orders.
4.2 Customer responsibility related to specific, in particular
safety-relevant applications
It has to be clearly pointed out that the possibility of a malfunction of electronic components
or failure before the end of the usual lifetime cannot be completely eliminated in the current
state of the art, even if the products are operated within the range of the specifications.
The same statement is valid for all software and software parts contained in or used with
or for products in the sensor product range of Würth Elektronik eiSos GmbH & Co. KG.
In certain customer applications requiring a high level of safety and especially in customer
applications in which the malfunction or failure of an electronic component could endanger
human life or health, it must be ensured by most advanced technological aid of suitable
design of the customer application that no injury or damage is caused to third parties in the
event of malfunction or failure of an electronic component.
4.3 Best care and attention
Any product-specific data sheets, manuals, application notes, PCN’s, warnings and cautions must be strictly observed in the most recent versions and matching to the products
revisions. This documents can be downloaded from the product specific sections on the
wireless connectivity and sensors homepage.
4.4 Customer support for product specifications
Some products within the product range may contain substances, which are subject to restrictions in certain jurisdictions in order to serve specific technical requirements. Necessary
information is available on request. In this case, the field sales engineer or the internal sales
person in charge should be contacted who will be happy to support in this matter.

4.5 Product improvements
Due to constant product improvement, product specifications may change from time to time.
As a standard reporting procedure of the Product Change Notification (PCN) according to
the JEDEC-Standard, we inform about major changes. In case of further queries regarding
the PCN, the field sales engineer, the internal sales person or the technical support team
in charge should be contacted. The basic responsibility of the customer as per section
and
4.2
remains unaffected.
The sensor driver software ¨Sensor SDK¨ and it’s source codes are not subject to the Product Change Notification information process.
4.1
4.6 Product life cycle
Due to technical progress and economical evaluation we also reserve the right to discontinue production and delivery of products. As a standard reporting procedure of the Product
Termination Notification (PTN) according to the JEDEC-Standard we will inform at an early
stage about inevitable product discontinuance. According to this, we cannot ensure that all
products within our product range will always be available. Therefore, it needs to be verified
with the field sales engineer or the internal sales person in charge about the current product
availability expectancy before or when the product for application design-in disposal is considered. The approach named above does not apply in the case of individual agreements
deviating from the foregoing for customer-specific products.
4.7 Property rights
All the rights for contractual products produced by Würth Elektronik eiSos GmbH & Co. KG
on the basis of ideas, development contracts as well as models or templates that are subject
to copyright, patent or commercial protection supplied to the customer will remain with Würth
