SC16IS741IPW,112

Controllers Overview

The SC16IS741IPW,112 is a single-channel UART with an I2C-bus or SPI interface manufactured by NXP USA Inc. It operates at 3.3 V or 2.5 V and supports baud rates up to 5 Mbit/s in 16× clock mode. The device features 64-byte transmit and receive FIFOs, auto hardware flow control using RTS/CTS, and automatic RS-485 support. It includes built-in IrDA SIR encoder/decoder support and software reset capabilities. Operating within the industrial temperature range of −40 °C to +95 °C, it utilizes a TSSOP16 package.

Controllers Feature Summary

• Backward-compatible register set with the standard 16C450 UART for easy software porting
• Integrated automatic RS-485 driver direction control via RTS signal
• Programmable Xon/Xoff characters for flexible software flow control
• Low sleep current consumption suitable for battery-operated handheld devices

Controllers Applications

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

Controllers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details and tape-and-reel specifications. Confirm that the component meets RoHS3 compliance standards required for your manufacturing environment. Ensure the selected variant matches the intended voltage operation and temperature range requirements for the final application design.

Controllers Selection Notes

Select this component when a single UART channel with low power consumption is required for I2C or SPI interfacing. Consider the backward compatibility with 16C450 registers if migrating existing firmware. Evaluate the need for automatic RS-485 support and IrDA SIR integration before choosing this specific model over other variants in the series.

Controllers Part Context
