telos is a leading vendor of I2C interfaces and monitors. We introduced our first I2C scanner in 1997 and have been working on new products and tools continuously.

Meanwhile there are several I2C tool vendors on the market. What makes our products different ? Well, there are several aspects but let's focus on

Software Excellence

For our I2C Tools we provide the software I2C Studio and the library I2C Framework for free. Both are outstanding, modern and powerful tools. Have a try and download them for evaluation.

Support

We are supporting all our products directly. You will get substantial feedback by one of our engineers within 24 hours on business days.

Quality

telos has been founded in 1988. More than 20 year of superior engineering expertise makes our product outstanding focusing on technical features, usability and, of course on quality. telos is ISO 9000 certified since 1997.

⁰) Product discontinued, not recommended for new designs

¹⁾The I2C Monitor Connii MM 2.0 does only recognize regular I2C transfers, no I2C error conditions etc., thus it is not well suited for finding problems on I2C communication level. The monitor stretches SCL, i.e. the SCL line is held low occasionally. That may lead to problems with master or slave devices that do not support SCL stretching (like some I2C single master implementations). Tracii XL 2.0 offers a more sophisticated I2C Monitor, which includes time stamps for every byte and error recognition.

²⁾In conjunction with our level shifter Levii and Optii the voltage range extends this way

Levii buses are supported down to 1.8 volts. Our second level shifter product
Optii works down to 1.5 volts and separates the I2C buses galvanically

³⁾I2C slave and master cannot be used simultaneously
