SC18IS600IPW,128

Controllers Overview

The SC18IS600IPW,128 is a bridge IC designed to interface between a host SPI bus and a serial I2C-bus. It operates as an I2C master controller, managing protocol, arbitration, and timing for direct communication with I2C slave devices. The device supports SPI Mode 3 at speeds up to 1.2 Mbit/s and I2C speeds up to 400 kbit/s. It features 96-byte transmit and receive buffers, four programmable GPIO pins, two quasi-bidirectional I/O pins, and 5 V tolerant I/Os. Operating voltage ranges from 2.4 V to 3.6 V, with power-down mode support via a WAKEUP pin. It is housed in a TSSOP16 package.

Controllers Feature Summary

• Acts as a bridge allowing SPI hosts to communicate directly with I2C-bus slave devices
• Functions as a single master I2C-bus controller handling all bus-specific sequences and arbitration
• Includes internal oscillator and configurable general-purpose input/output pins

Controllers Applications

• Enabling microcontrollers with only SPI interfaces to access I2C peripherals
• System integration requiring protocol conversion between SPI masters and I2C slaves
• Low-power embedded designs utilizing the dedicated power-down mode

Controllers Procurement Notes

Verify component authenticity through official NXP channels or authorized distributors. Confirm the specific ordering suffix matches the required packaging and marking specifications. Check current lifecycle status as availability may vary by region. Ensure environmental compliance documentation aligns with project requirements before finalizing procurement orders.

Controllers Selection Notes

Select this component when an SPI-only host must interface with I2C devices without software overhead. Ensure the system voltage falls within the 2.4 V to 3.6 V range. Verify that the required I2C clock frequency is supported by the internal oscillator configuration. Consider the TSSOP16 package constraints for PCB layout and thermal management during the design phase.

Controllers Part Context

This part belongs to the SC18IS600 series of SPI to I2C-bus interface controllers manufactured by NXP Semiconductors. It serves as a hardware bridge solution, eliminating the need for complex software drivers on the host side to manage I2C protocols over an SPI connection. The series focuses on reducing system complexity and board space.

Controllers Replacement Considerations

The SC18IS604PW is documented as a functional replacement for the SC18IS600IPW. When substituting, verify compatibility regarding buffer sizes, GPIO pin counts, and supply voltage ranges to ensure seamless integration into existing designs.
