Hi - are there any microcontrollers out there that support I2C high speed mode? (3.4Mbps - defined in the I=B2C-bus specification, Version2=2E0). I can't find any that do. I can't even find any NXP parts that do!
Also - has anybody ever used an I2C bus extender chip? (ie the NXP P82B715). What was your experience with it? Are there any that can handle higher speeds that that one? (1Mbps+)
