Abstract
This document discusses, among other things, a multi-address Inter-Integrated Circuit (IC) selection circuit configured to receive a number (N) of identification (ID) signals from a corresponding number (N) of ID pins of a slave IC device and at least one of a data signal from a serial data line (SDA) of an IC bus or a clock signal from a serial clock line (SCL) of the IC bus, and to determine one of 4 to the power of N (4) selectable IC addresses using the number (N) of ID signals and at least one of the data signal or the clock signal. In an example, the multi-address IC selection circuit can determine 4 selectable IC addresses using a single ID signal from a single ID pin of the slave IC device.
