I2C Interface

Feature

The I2C interface has the following features;



Reference I/O power supply: VDDIO



Channel number: 2 for QFN package



I2C bus interface



I2C bus master operation and slave operation (not support the multi master operation)



Cross stretch is supported.



Serial clock frequency:

Standard mode (Max. 100 kHz) and Fast mode (Max. 400 kHz)



Serial clock output mode:

Open-drain output or CMOS output can be selected.



Device address format:

7-bit address (10-bit address is not supported.)

The I2C interface operates at the VDDIO power supply voltage. Because the power supply pin is shared with other hardware

interfaces, the voltage of the I2C interface cannot be independently different.

When TC35681 is used in the User-App mode, Channel 1 is occupied as an interface to the memory which stores a user application

program. For the details, refer to Section 3.4.3.
