SC18IS602IPW,128

Controllers Overview

The SC18IS602IPW,128 is an I2C-bus to SPI bridge manufactured by NXP Semiconductors. It operates as an I2C slave and SPI master, enabling microcontrollers with only I2C interfaces to communicate with SPI devices. The device features a 200-byte data buffer and supports up to four slave select outputs (SS0-SS3). It includes an internal oscillator and active LOW interrupt output. Operating voltage ranges from 2.4 V to 3.6 V. The I2C interface supports speeds up to 400 kHz, while the SPI master interface operates up to 1.8 Mbit/s. It is housed in a 16-pin TSSOP package.

Controllers Feature Summary

• Converts I2C bus commands into SPI master operations
• Includes a 200-byte deep data buffer for communication
• Provides up to four programmable slave select outputs
• Features an internal oscillator for clock generation

Controllers Applications

• Converting I2C-bus to SPI
• Adding additional SPI bus controllers to an existing system

Controllers Procurement Notes

Verify the specific ordering suffix ',128' against official NXP documentation to confirm tape and reel packaging details. Ensure the component matches the standard SC18IS602IPW specifications regarding the 16-lead TSSOP package and industrial temperature range. Confirm that the 'B' variant designation is not required if SS2 functionality is needed, as the base model lacks this pin support.

Controllers Selection Notes

Select the SC18IS602IPW when an internal oscillator is preferred over an external clock source. Note that this specific version does not support the SS2 function; use the SC18IS602BIPW variant if SS2/GPIO2 capability is required. Ensure the system voltage falls within the 2.4 V to 3.6 V range and that the I2C address bits A0-A2 are configured correctly for the target bus topology.

Controllers Part Context

This component belongs to the SC18IS60x family of protocol bridges. It shares the same physical package and core architecture with the SC18IS602BIPW and SC18IS603IPW. The primary distinction lies in the presence of the internal oscillator versus external clock requirements and the availability of the SS2 pin configuration.

Controllers Replacement Considerations

SC18IS602BIPW offers identical functionality with added SS2 support. SC18IS603IPW requires an external clock but supports higher SPI speeds up to 4 Mbit/s.
