SC16C754BIBM,157

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C754BIBM,157 is a quad Universal Asynchronous Receiver/Transmitter (UART) manufactured by NXP Semiconductors. It features four independent UART channels with 64-byte transmit and receive FIFOs. The device supports data rates up to 5 Mbit/s at 3.3 V and 5 V supply voltages, and up to 3 Mbit/s at 2.5 V. It operates within an industrial temperature range of -40 °C to +85 °C. The component is housed in a plastic LQFP64 package with dimensions of 7 × 7 × 1.4 mm. It includes automatic hardware and software flow control capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Four independent UART channels with 64-byte FIFOs for each transmitter and receiver
• Supports 2.5 V, 3.3 V, and 5 V operation with 5 V tolerant input pins
• Integrated automatic hardware flow control using auto-RTS and auto-CTS functions
• Programmable software flow control with configurable Xon/Xoff characters

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring multiple serial interfaces
• Embedded controllers needing high-speed asynchronous data transfer
• Modem interface applications with hardware flow control requirements

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix '157' against official NXP documentation to confirm tape and reel packaging or specific quality grade. Confirm the manufacturer source directly from NXP Semiconductors rather than distributor listings. Ensure the part number matches the LQFP64 package variant specified in the datasheet.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a system requires four independent UART interfaces with substantial buffering to reduce processor overhead. It is suitable for designs operating at 3.3 V or 5 V logic levels. Consider the LQFP64 package constraints if board space is limited. Verify compatibility with existing TL16C754 software drivers if migrating from Texas Instruments components.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The SC16C754BIBM belongs to the SC16C754B family of quad UARTs. It is pin-compatible with the SC16C654IA68, TL16C754, and SC16C554IA68, facilitating direct replacements in many designs. The IBM suffix denotes the LQFP64 plastic low profile quad flat package variant.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C754BIBM is pin-compatible with the TL16C754. Software compatibility with TL16C754 is also supported. Other compatible packages include SC16C754BIB80 (LQFP80) and SC16C754BIA68 (PLCC68).
