C Interface 

I

2

C is a serial, 8-bit oriented data transfer bus for bit rates up to 400kbps in Fast mode. It 

consists of two lines, the serial data line I2CDAT and the serial clock line I2CCLK.  
 
The TC65 module acts as a single master device, e.g. the clock I2CCLK is driven by module. 
I2CDAT is a bi-directional line. 
 
Each device connected to the bus is software addressable by a unique 7-bit address, and 
simple master/slave relationships exist at all times. The module operates as master-
transmitter or as master-receiver. The customer application transmits or receives data only 
on request of the module.  
 
To configure and activate the I

2

C bus use the AT^SSPI command. If the I

2

C bus is active the 

two lines I2CCLK and I2DAT are locked for use as SPI lines. Vice versa, the activation of the 
SPI locks both lines for I

2

C. Detailed information on the AT^SSPI command as well 

explanations on the protocol and syntax required for data transmission can be found in [1]. 
 
The I

2

C interface can be powered from an external supply or via the VEXT line of TC65. If 

connected to the VEXT line the I

2

C interface will be properly shut down when the module 

enters the Power-down mode. If you prefer to connect the I

2

C interface to an external power 

supply, take care that VCC of the application is in the range of V

VEXT

 and that the interface is 

shut down when the PWR_IND signal goes high. See figures below as well as Section 7 and 
Figure 38. 
 
In the application I2CDAT and I2CCLK lines need to be connected to a positive supply 
voltage via a pull-up resistor.  
 
For electrical characteristics please refer to Table 17.
