Description

The SC183ULTRT is an electronic component model in the product category of IC chips. It is designed as an interface between the standard SPI of a host and the serial I2C-bus, allowing the host to communicate directly with other I2C-bus devices. The SC183ULTRT can function as an I2C-bus master-transmitter or master-receiver and controls all the I2C-bus specific sequences, protocol, arbitration, and timing. The main difference between the SC183ULTRT and the SC183ULTRT lies in the clock source, with the former having an internal clock source and the latter having an external clock source.
