telos successfully designs, develops and sells a wide range of I2C hard- and software for more than ten years. Whether you need a sophisticated analysing tool for monitoring complex traffic on an I2C Highspeed bus or simply a reliable high-quality easy-to-use I2C interface to access an EEPROM: Talk to us, we offer the solution which best fits your needs.
All of our products come with superior software packages, maybe you find some time to check them. Most of the software can easily be downloaded from this web for test purposes.
We believe that offering high-end production and laboratory equipment does not mean to sell packages off-the-shelf. Instead, we provide our customers with qualified support before, during and after sales. All sales and support team members are experienced developers holding a masters degree in engineering or computer science.
Because our customers including most major electronic component vendors expect to talk to partners who speak their language and quickly understand their specific problems.
The I2C bus is used in many different ways requiring considerable integration knowledge which you can certainly expect from us.
This is one of the reasons for us not to sell our equipment through distributors. Such sales facilities are convenient during purchase transactions; however, we think that all customer support should be done by the people who best know our products, i.e. directly by telos.
We realize that there are several I2C interfaces on the market. Therefore we would like to give you some background on why we believe that our solutions are better suited for most applications then others.
telos is not a distributor. All design, development, sales and support activities are performed in one place with a qualified team of engineers. No, we do not assign tasks to freelancers, low cost developers, foreign outsourcing partners or distributors. We focus on industrial products and this means to assure long term quality in terms of product support, robustness, customer awareness and availability.
But what does this mean for you? Here are some examples.
Please note that telos offers solutions for the I2C 
Highspeed standard which have been developed in close cooperation with NXP (formerly Philips Semiconductors). These include appropriate hardware as well as programming software containing dedicated NXP (formerly Philips Semiconductors) algorithms for UOC3 devices.

1) The I2C Monitor 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 product 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.
