SC18IM700
Master I2C-bus controller with UART interface
Rev. 3 — 12 October 2017
Product data sheet
1. 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.
