The SC18IS602BIPW,112 is an I2C-bus to SPI Bridge. It 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. It operates as an I2C-bus slave-transmitter or slave-receiver and an SPI master. This controls all the SPI bus-specific sequences, protocol and timing. It has its own internal oscillator and it supports four SPI chip select outputs that may be configured as GPIO when not used.
I2C-bus Slave interface operating up to 400kHz
SPI master operating up to 1.8Mbps
200-byte Data buffer
Up to four slave select outputs
Up to four programmable I/O pins
Low power mode
Internal oscillator option
Active low interrupt output
Latch-up testing is done to JEDEC standard JESD78 that exceeds 100mA
