SC18IS606PWJ

Controllers Overview

The SC18IS606PWJ is an I2C-bus to SPI bridge manufactured by NXP Semiconductors. It enables microcontrollers with only an I2C interface to communicate directly with SPI devices. The device operates as an I2C target and an SPI controller, managing all protocol and timing sequences internally. It features a 1024-byte data buffer, three programmable chip select outputs (configurable as GPIO), and an internal oscillator. Operating supply voltage ranges from 1.71 V to 3.6 V, with an operating temperature range of -40 °C to +105 °C. The I2C interface supports speeds up to 400 kHz, while the SPI controller supports rates up to 1.875 MHz.

Controllers Feature Summary

• Acts as a transparent bridge between I2C controllers and SPI peripherals
• Includes a 1024-byte deep data buffer for message storage
• Features three configurable chip select outputs that can function as general-purpose I/O pins
• Provides low-power idle mode and active-low interrupt output

Controllers Applications

• Converting I2C-bus signals to SPI protocol
• Adding additional SPI bus controllers to existing I2C-based systems

Controllers Procurement Notes

Verify the ordering suffix 'J' corresponds to the reel packing method specified in the official documentation. Confirm the package type is TSSOP16 (SOT403-1) and check the temperature grade matches the required industrial range. Ensure the pinout orientation aligns with design constraints, as the device rotation differs from previous models like the SC18IS602B.

Controllers Selection Notes

Select this component when an I2C-only host must interface with SPI slaves without adding a dedicated SPI controller. Consider the 1024-byte buffer depth for large data transfers. Verify that the 1.71 V minimum supply voltage meets system requirements, as it is lower than the 2.4 V requirement of the legacy SC18IS602B. Check if the three available chip selects are sufficient for the target peripheral count.

Controllers Part Context

The SC18IS606 serves as a functional replacement for the SC18IS602B, offering a new pinout and increased buffer capacity. Unlike its predecessor, it lacks quasi-bidirectional mode support but provides a wider operating voltage range and extended temperature capability. It belongs to the SC18IS60x family of bridge ICs designed for protocol conversion tasks.

Controllers Replacement Considerations

SC18IS602B is the primary functional predecessor, though pinouts and electrical characteristics differ significantly.
