SC16C750BIBS,128

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C750BIBS,128 is a single-channel Universal Asynchronous Receiver and Transmitter (UART) manufactured by NXP Semiconductors. It operates at supply voltages of 2.5 V, 3.3 V, or 5 V and supports data rates up to 3 Mbit/s at 5 V, 2 Mbit/s at 3.3 V, and 1 Mbit/s at 2.5 V. The device features 64-byte transmit and receive FIFOs with programmable trigger levels and automatic hardware flow control. It is housed in an HVQFN32 package and functions within an industrial temperature range of -40 °C to +85 °C.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Pin-compatible with industry-standard TL16C750 and functionally equivalent to 16C450 after reset
• Includes 64-byte transmit and receive FIFOs with selectable interrupt trigger levels
• Supports automatic hardware flow control via RTS and CTS signals
• Provides internal loopback capability for on-board diagnostics

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• High-speed modem interfaces requiring fast data processing
• Shared network environments needing efficient bandwidth management

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix IBS corresponds to the HVQFN32 package variant when sourcing. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Ensure the supplier provides valid traceability documentation for this NXP Semiconductors part number.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this UART when upgrading from legacy 16C450 designs without changing pin layouts. It is suitable for applications requiring reduced CPU overhead through large FIFO buffers. Verify voltage compatibility with the host system's logic levels before integration.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the SC16C750B family of UART interface controllers. It serves as a drop-in replacement for older 16C450/550 devices while offering enhanced performance through larger buffer depths and advanced flow control mechanisms.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Functionally compatible with TL16C750 and ST16C450 variants. Software migration from standard 16C450 drivers is supported due to register set backward compatibility.
