SC16C754BIBM,151

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C754BIBM,151 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, and up to 3 Mbit/s at 2.5 V. It operates within a supply voltage range of 2.25 V to 5.5 V and an industrial temperature range of -40 °C to +85 °C. The component is housed in a 64-lead LQFP plastic package.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Four independent UART channels with 64-byte FIFOs for each transmitter and receiver
• Supports software (Xon/Xoff) and hardware (RTS/CTS) flow control with programmable trigger levels
• Integrated modem control functions including CTS, RTS, DSR, DTR, RI, and CD signals
• Fully prioritized interrupt system with six interrupt levels and internal loopback capability

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring multi-channel serial connectivity
• Embedded controllers needing DMA signaling capabilities for high-speed data transfer
• Modem interface applications utilizing hardware flow control and status monitoring

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix IBM against the manufacturer's current documentation to confirm package type and lead-free status. Confirm availability as distribution listings may indicate end-of-life or limited stock status. Ensure the source document matches the exact part number variant required for your design specifications.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when multiple UART interfaces are required on a single chip. It is suitable for designs needing pin compatibility with legacy TL16C754 or SC16C654IA68 devices while offering enhanced FIFO and flow control features. Verify that the LQFP64 package fits the PCB layout constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SC16C754B family of quad UARTs from NXP. It is functionally compatible with the SC16C554 and SC16C654 series but includes additional enhancements such as larger FIFOs and advanced flow control registers. The IBM suffix specifically denotes the LQFP64 plastic low profile quad flat package variant.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C754BIBM is pin-compatible with the SC16C654IA68, TL16C754, and SC16C554IA68. These parts can serve as direct replacements if software compatibility with TL16C754 is maintained. Verify that the replacement part supports the required 64-byte FIFO depth and 5 Mbit/s data rate.
