Overview
The SC18IS602BIPW,112 is an I²C-bus to SPI bridge designed by NXP Semiconductors. This component serves as an interface between a standard I²C-bus of a microcontroller and an SPI bus, enabling the microcontroller to communicate directly with SPI devices through its I²C-bus. The SC18IS602B operates as both an I²C-bus slave-transmitter or slave-receiver and an SPI master, controlling all the SPI bus-specific sequences, protocol, and timing.
