Q&A Sheet 14

Question: Which microcontrollers do have an on-chip I2C interface?

A LOT of MCU's have a real I2C interface implemented in hardware, but this should not restrict the use of the I2C bus on other MCU's. ANY MCU can be made to talk to I2C using some small software routines.

There are microcontrollers with on-chip I2C modules as well as stand-alone I2C bus peripherals.

To list all the devices here would be impossible. A good overview can be found here: http://www.embeddedlinks.com/chipdir (search for keyword I2C)
