SC18IM700

www.DataSheet4U.com SC18IM700 Master I2C-bus controller with UART interface Rev. 01 — 28 February 2006 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. 2.
