SC18IS604-EVB evaluation board
1 Introduction
SC18IS604 is designed to serve as an interface between the standard SPI of a host
(microcontroller, microprocessor, chip set, etc.) and the serial I
2
C-bus. This allows the
host to communicate directly with other I
2
C-bus devices. SC18IS604 can operate as
an I
2
C-bus master-transmitter or master-receiver. SC18IS604 controls all the I
2
C-bus
specific sequences, protocol, arbitration and timing.
This document is intended to help the users to quickly setup, configure and operate the
SC18IS604-EVB evaluation board in the users’ hardware platform.

4 Getting to know the hardware
The SC18IS604-EVB board is designed to be connected to an external SPI master via
a 7-pin male (JP1) header. The SC18IS604-EVB evaluation board has an on-board I
2
C
slave serial EEPROM and an I
2
C slave LED blinker, which can be directly accessed by
the external SPI master via SC18IS604. The external SPI master can write, read, and
program the serial EEPROM/LED blinker without requiring an I
2
C slave to be connected
to the board.
The 3V3 power for the evaluation board should be supplied via this I
2
C interface header
as well.
The SC18IS604-EVB evaluation board also has an I
2
C interface header (JP4) to allow
other I
2
C slave devices to be connected to the SC18IS604-EVB evaluation board. These
