0) Product discontinued, not recommended for new designs

1)The I2C Monitor telos 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). telos 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

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

3)I2C slave and master cannot be used simultaneously
