SC18IS602B
I²C-bus to SPI bridge
Rev. 5 — 3 August 2010
Product data sheet
1. General description
The SC18IS602B is designed to serve as an interface between a standard I²C-bus of a
microcontroller and an SPI bus. This allows the microcontroller to communicate directly
with SPI devices through its I²C-bus. The SC18IS602B operates as an I²C-bus
slave-transmitter or slave-receiver and an SPI master. The SC18IS602B controls all the
SPI bus-specific sequences, protocol, and timing. The SC18IS602B has its own internal
oscillator, and it supports four SPI chip select outputs that may be configured as GPIO
when not used.
