Figure 6.10.1-1 Block Diagram
The I²C slave interface operates in 7 bit addressing mode with a maximum frequency of 400 kHz (fast mode).
To synchronize the ASIC to different operation voltages of the I²C bus the interface has a separate supply
voltage input at pin V
please refer to the “I²C – BUS SPECIFICATION VERSION 2.1” from Philips.
