PIC18F4685 I2C question.

[RageOfFury]

Can a PIC18F4685 with a supply voltage of 5V communicate with an I2C device which has a supply voltage of 3.3V?

Thanx

You can do it without using level translators if you use software i2c
on any of the Port B pins, and use pull-up resistors connected to +3.3v.
This works with a 3.3v i2c chip because the i/o pins on Port B have
TTL input levels. You can use 3.3K resistors for the pull-ups. That's
a 1 ma pull-up, and it's equivalent to using 4.7K in a 5v circuit.

Thanx for the reply. After discussing it with one of my teachers, he recommended I use a PCA9306, which is a I2C level translator.
