Introduction
SC18IS604PWJ - SPI-to-I²C Bridge Chip
Product Overview
SC18IS604PWJ is an SPI-to-I²C bridge chip designed for embedded, industrial, IoT and automotive applications, providing seamless interface conversion between SPI hosts and I²C-bus peripherals.
Core Functions
This bridge chip acts as an interface between the standard SPI port of host devices (microcontrollers, microprocessors, chipsets) and serial I²C-bus peripherals, enabling direct communication between the host and various I²C-bus devices.
It operates as an I²C-bus controller-transmitter or controller-receiver, independently managing all I²C-bus-specific communication sequences, protocols, bus arbitration and timing control.
Key Features
- High-speed SPI interface with transmission rate up to 1.2 Mbit/s
- Fast-mode I²C-bus supporting 375 kHz operation
- Built-in 255-byte transmit/receive FIFO buffer for stable data transmission
- 5 general-purpose input/output (GPIO) pins for auxiliary control
- Wide operating voltage: 1.71 V - 3.6 V with 5 V-tolerant I/O pins
- Operating temperature range: −40 °C to +105 °C for industrial-grade applications
Applications
- Embedded System Peripheral Expansion: Connect SPI-only MCUs to I²C sensors, EEPROMs, real-time clock chips, and I/O expanders
- Industrial Control Modules: Bridge communication interfaces for industrial sensors and actuators
- Consumer Electronics: Smart home devices, wearable equipment, and portable electronic hardware
- Automotive Electronics: On-board auxiliary control modules with wide-temperature-range requirements
- IoT Devices: Low-power edge nodes for multi-sensor data collection and transmission
