Description

The SC18IS600IPW112 is an electronic component model that acts as an interface between the standard SPI of a host device and the serial I2C-bus, allowing direct communication with other I2C-bus devices. It can operate as an I2C-bus master-transmitter or master-receiver, controlling all the I2C-bus specific sequences, protocol, arbitration, and timing. The main difference between the SC18IS600 and SC18IS601 lies in the clock source, with the SC18IS600 using an internal clock and the SC18IS601 using an external clock.
