SC18IS602IPW,112

Controllers Overview

The SC18IS602IPW,112 is an I²C-bus to SPI bridge IC manufactured by NXP Semiconductors. It enables a microcontroller with an I²C interface to communicate directly with SPI devices. The device operates as an I²C slave and an SPI master, handling all protocol and timing sequences. Key specifications include an operating supply voltage range of 2.4 V to 3.6 V, an internal oscillator, and a 200-byte data buffer. It supports I²C speeds up to 400 kHz and SPI speeds up to 1.8 Mbit/s. The component is housed in a 16-lead TSSOP package.

Controllers Feature Summary

• Acts as a bridge between standard I²C buses and SPI interfaces
• Features an internal oscillator for standalone clock generation
• Includes a 200-byte deep data buffer for communication
• Provides up to four programmable slave select outputs or GPIO pins

Controllers Applications

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

Controllers Procurement Notes

Verify the specific ordering suffix '112' against official documentation to confirm tape and reel packaging details. Confirm that the SC18IS602 variant without the 'B' designation lacks SS2 support, requiring its use strictly as GPIO2. Ensure compatibility with the required 2.4 V to 3.6 V supply voltage range during integration.

Controllers Selection Notes

Select this component when an I²C master must interface with SPI peripherals without software bit-banging. Choose the SC18IS602 over the SC18IS603 if an internal oscillator is preferred over an external clock source. Note that the SC18IS602 lacks the SS2 function available on the SC18IS602B, which may impact multi-device selection requirements.

Controllers Part Context

This part belongs to the SC18IS60x family of I²C-to-SPI bridges from NXP. It shares core functionality with the SC18IS602B and SC18IS603 but differs in specific pin configurations and clock sources. The SC18IS602 specifically utilizes an internal RC oscillator, whereas the SC18IS603 requires an external clock input.

Controllers Replacement Considerations

The SC18IS606PW is documented as a functional replacement for the SC18IS602BIPW. Verify if the SC18IS606 meets the specific requirements for the SC18IS602, noting differences in buffer size and GPIO availability.
