SC16IS740IPW,128

Controllers Overview

The SC16IS740IPW,128 is a single-channel UART interface controller manufactured by NXP Semiconductors. It bridges I2C-bus or SPI interfaces to a high-performance UART with baud rates up to 5 Mbit/s in 16x clock mode. The device features 64-byte transmit and receive FIFOs, IrDA SIR support, and software reset capabilities. Operating at 3.3 V or 2.5 V, it supports industrial temperature ranges from -40 °C to +95 °C. Packaged in TSSOP16, the component ensures low operating current and sleep modes below 30 μA.

Controllers Feature Summary

• Supports selectable I2C-bus or SPI interfaces for seamless protocol conversion
• Includes 64-byte FIFOs for both transmitter and receiver operations
• Features built-in IrDA encoder and decoder interface
• Provides auto hardware flow control using RTS/CTS signals

Controllers Applications

• Factory automation and process control systems
• Portable and battery-operated devices
• Cellular data devices

Controllers Procurement Notes

Verify the specific ordering suffix

Controllers Selection Notes

Select this model when a single UART channel with I2C or SPI connectivity is required. Ensure the application operates within the specified voltage range of 2.5 V to 3.3 V. Consider the TSSOP16 package constraints for PCB layout. Verify that the host system can support the selected interface speed and interrupt handling requirements.

Controllers Part Context

This component belongs to the SC16IS740/750/760 family of UART controllers. It shares functional and electrical characteristics with the SC16IS750, except the SC16IS740 lacks the additional programmable I/O pins found on the SC16IS750. It is backward-compatible with the 16C450 register set, facilitating software porting from legacy platforms.

Controllers Replacement Considerations

The SC16IS750IPW serves as a functional substitute, offering identical UART performance but including eight additional programmable I/O pins. Designers must account for the pinout differences and ensure unused GPIO pins are handled correctly if substituting into an existing SC16IS740 footprint.
