SC18IS602B 2 I C-bus to SPI bridge Rev. 7 21 October 2019 Product data sheet 1. General description 2 The SC18IS602B is designed to serve as an interface between a standard I C-bus of a microcontroller and an SPI bus. This allows the microcontroller to communicate directly 2 2 with SPI devices through its I C-bus. The SC18IS602B operates as an I C-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. 2. Features and benefits 2 I C-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 3.
