SC16C754BIA68,512

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SC16C754BIA68,512 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 PLCC68 plastic leaded chip carrier package.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Supports 5 V, 3.3 V, and 2.5 V operation with pin compatibility to legacy TL16C754 designs.
• Includes automatic hardware flow control via auto-RTS and auto-CTS to prevent overrun errors.
• Provides programmable software flow control using configurable Xon/Xoff characters.
• Features a prioritized interrupt system with selectable FIFO trigger levels for DMA and interrupt generation.

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring multiple serial ports
• 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 against official NXP documentation to confirm package type and tape/reel specifications. Confirm that the PLCC68 variant matches the target PCB footprint. Check current production status as older variants may be discontinued or subject to last-time buy notices.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when four independent UART channels are required on a single IC. Ensure the design supports the PLCC68 package dimensions. Verify that the host processor can interface with the 8-bit parallel bus and that the voltage levels match the 3.3 V or 5 V operational requirements.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the SC16C754B family of quad UARTs. It is functionally compatible with the TL16C754 but offers enhanced features such as larger FIFOs and improved flow control logic. The IA68 designation specifically refers to the PLCC68 package option within the broader product line.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

Pin-compatible replacements include the SC16C654IA68 and SC16C554IA68. Software compatibility exists with the TL16C754. Verify that any substitute maintains the 64-byte FIFO depth and industrial temperature rating.
