BUS INTERFACE

GENERAL DESCRIPTION

The I2C bus is a two-way, two-line serial communication

between different integrated circuits. The two lines are:

a serial Data line (SDA) and a serial Clock line (SCL). All

Summit Microelectronics parts support a 100kHz clock

rate, and some support the alternative 400kHz clock.

Check Table 2 for the value of fSCL. The SDA line must

be connected to a positive supply by a pull-up resistor

located on the bus. Summit parts have a Schmitt input on

both lines. See Figure 5 and Table 2 for waveforms and

timing on the bus. One bit of Data is transferred during

each Clock pulse. The Data must remain stable when the

Clock is high.
