SC18IS604PWJ

Controllers Overview

The SC18IS604PWJ is an SPI to I2C-bus bridge manufactured by NXP Semiconductors. It enables a host microcontroller with an SPI interface to communicate directly with I2C-bus devices. The device operates as an I2C controller, managing protocol and timing. Key specifications include a supply voltage range of 1.71 V to 3.6 V, a maximum SPI clock frequency of 1.2 MHz, and a Fast-mode I2C bus speed of 375 kHz. It features 255-byte transmit and receive buffers, five GPIO pins, and an internal oscillator. The component is housed in a TSSOP16 package.

Controllers Feature Summary

• Acts as a bridge between SPI master interfaces and I2C target devices
• Includes 255-byte transmit and receive data buffers
• Features five programmable general-purpose input/output pins
• Supports deep power-down mode with chip select wake-up

Controllers Applications

• Enabling SPI-based microcontrollers to access I2C sensors
• Connecting SPI processors to I2C EEPROMs or real-time clocks
• System integration where I2C peripherals are required but only SPI is available on the main controller

Controllers Procurement Notes

Verify that the ordering suffix 'J' corresponds to the reel packing method specified in the official documentation. Confirm the operating temperature range requirements match the -40 °C to +105 °C specification. Ensure the design accommodates the TSSOP16 package dimensions and pin configuration before finalizing procurement.

Controllers Selection Notes

Select this component when an SPI-to-I2C translation is required for low-voltage systems starting at 1.71 V. It serves as a functional replacement for the SC18IS600, offering increased buffer capacity and extended temperature ranges. Consider the specific pinout differences and the absence of quasi-bidirectional GPIO modes compared to legacy counterparts.

Controllers Part Context

This part belongs to the SC18IS604 series of specialized interface controllers. It is designed to facilitate communication between different serial protocols within embedded systems. The device simplifies system architecture by removing the need for software-based protocol emulation on the host processor.

Controllers Replacement Considerations

The SC18IS604PW is documented as a functional replacement for the SC18IS600IPW. Designers should account for the new pinout, increased buffer sizes, and modified GPIO configurations when transitioning from the older model.
