SC18IM704PWJ

SC18IM704PWJ is a UART to I²C-bus bridge. It 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. It can operate as an I²C-bus controller. It controls all the I²C-bus specific sequences, protocols, arbitration, and timing. The host communicates with SC18IM704 with ASCII messages protocol; this makes the control sequences from the host to SC18IM704 very simple. The application includes enabling I²C-bus controller support in a system, I²C-bus instrumentation and control, industrial control, medical equipment, cellular telephones, and handheld computers.
