Posted on May 17, 2011 at 11:34Spen, Thanks for the I2C specs. But my question is more simple : Is ST92F150 (5V) work with 3.3V devices with only 3.3V pull-ups on SDA and SCL lines ? fred.
Posted on May 17, 2011 at 11:34Hi, I have some problems with ST92F150 electrical characteristics for IOs Schmitt trigger (vih,vil,hyst), especially for I2C. For me, Hyst = Vih - Vil, but ST9 specs do not fit with this equation. Could anyone clarify ...
