SC16IS741IPW,118

Controllers Overview

The SC16IS741IPW,118 is a single-channel high-performance UART featuring an I2C-bus or SPI slave interface. It supports data rates up to 5 Mbit/s and operates at 3.3 V or 2.5 V. The device includes 64-byte transmit and receive FIFOs, fully compatible with the 16C450 register set. It offers automatic hardware and software flow control, IrDA SIR support, and software reset capabilities. Operating temperature ranges from -40 °C to +95 °C in the TSSOP16 package.

Controllers Feature Summary

• Backward-compatible internal register set with the widely used 16C450 standard for easy software porting.
• Integrated automatic RS-485 support with driver direction control via RTS signal and address detection.
• Built-in IrDA encoder and decoder interface supporting SIR protocols.
• Independent enable/disable functionality for transmitter and receiver operations.

Controllers Applications

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

Controllers Procurement Notes

Verify the specific ordering suffix against official NXP documentation to confirm exact packaging and environmental compliance details. Confirm current availability status as distribution channels may vary. Ensure the selected variant matches the required interface configuration and voltage specifications for the target application design.

Controllers Selection Notes

Select this component when a bidirectional protocol converter between I2C/SPI and RS-232/RS-485 is required. Ensure the host system can utilize the 16C450-compatible register map. Verify that the TSSOP16 package dimensions fit the PCB layout constraints and that the industrial temperature range meets the operational environment requirements.

Controllers Part Context

This part belongs to the SC16IS741 family of single-channel UART bridge ICs manufactured by NXP Semiconductors. It serves as a bridge between parallel bus interfaces like I2C or SPI and serial asynchronous communication standards. The family is designed for applications requiring low power consumption and seamless integration into existing 16C450-based software architectures.

Controllers Replacement Considerations

SC16IS741AIPWJ is a documented functional substitute within the same product family offering identical core specifications and pinout compatibility.
