SC16C754BIBM,128

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C754BIBM,128 is a quad Universal Asynchronous Receiver/Transmitter (UART) manufactured by NXP Semiconductors. It features four independent 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 2.5 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 package.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Four independent UART channels with 64-byte FIFOs for each transmitter and receiver
• Supports hardware flow control via auto-RTS and auto-CTS, and software flow control using programmable Xon/Xoff characters
• Programmable baud rate generator with selectable trigger levels for DMA and interrupt generation
• Internal loopback capability for on-board diagnostics and comprehensive modem control functions

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring multi-channel serial connectivity
• Embedded controllers managing multiple peripheral devices via UART interfaces
• Data acquisition systems utilizing DMA signaling for high-speed data transfer

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and environmental compliance. Confirm availability status as distribution channels may list discontinued variants. Ensure the intended application environment matches the specified industrial temperature range and voltage requirements before finalizing procurement.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a system requires four distinct UART interfaces within a single integrated circuit. Consider the 64-byte FIFO depth for applications demanding reduced processor overhead through DMA or interrupt-driven operations. Verify that the host system provides compatible 5 V tolerant input pins if operating at higher voltage levels.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SC16C754B family of quad UARTs from NXP Semiconductors. It is pin-compatible with legacy devices such as the TL16C754 and SC16C554, facilitating direct replacements in existing designs while offering enhanced features like larger FIFOs and improved flow control mechanisms.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The SC16C754BIBM is functionally compatible with the SC16C754IB80 and SC16C754BIA68, provided the physical package dimensions are accommodated. Direct pin-for-pin replacement is possible with older generations like the TL16C754 due to architectural similarities.
