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.
