The way you can notice the latter if you see separate read and write addresses specified – that’s a non-shifted address. A surefire way is to connect your device to any I2C controller and scan ...

If you want smaller PCB footprint, better parameters, or more channels, there are level shifter chips, with many of them wonderfully suited for I2C (read the datasheet!). As we’ve featured ...

The DB-I2C-S-APB-BRIDGE is an I2C Slave Controller IP Core focused on low VLSI footprint ASIC / ASSP designs not requiring internal configuration & control registers (and thus no local host CPU ...
