General description

The SC18IM700 is designed to serve as an interface between the standard UART port of

a microcontroller or microprocessor and the serial I2C-bus; this allows the microcontroller

or microprocessor to communicate directly with other I2C-bus devices. The SC18IM700

can operate as an I2C-bus master. The SC18IM700 controls all the I2C-bus speciﬁc

sequences, protocol, arbitration and timing. The host communicates with SC18IM700 with

ASCII messages protocol; this makes the control sequences from the host to the

SC18IM700 become very simple.
