I2C address resolution

If I have a specific chip to put on an I2C buss is it possible to attach multiple copies of this chip on the same I2C buss ? It should create and address conflict normally.

Can you show me a document that goes through figuring the pullup resistors in multiple scenerios step by step ?

Hi randyseedle,

Some I2C slave chip can configure address by pin connection. If their address are different, you can put on multiple device on the bus.

Jing
