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.
●Features and benefits
●I2C-bus slave interface operating up to 400 kHz
●SPI master operating up to 1.8 Mbit/s
●200-byte data buffer
●Up to four slave select outputs
●Up to four programmable I/O pins
●Operating supply voltage: 2.4 V to 3.6 V
●Low power mode
●Internal oscillator option
●Active LOW interrupt output
●ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101
●Latch-up testing is done to JEDEC Standard JESD78 that exceeds 100 mA
●Very small 16-pin TSSOP
●Applications
●Converting I2C-bus to SPI
●Adding additional SPI bus controllers to an existing system
