TL16CP754CPMR

Overview

The TL16CP754CPMR is a quad universal asynchronous receiver/transmitter (UART) integrated circuit manufactured by Texas Instruments. It features four independent UART channels, each equipped with a 64-byte FIFO buffer to enhance data throughput and reduce processor intervention. The device supports data rates up to 3 Mbps and operates within a supply voltage range of 2.7 V to 5.5 V. It is housed in a 68-pin PLCC package and includes automatic flow control capabilities.

Feature Summary

• Integrates four independent UART channels with 64-byte FIFOs for efficient serial communication management.
• Supports baud rates up to 3 Mbps with automatic hardware flow control to prevent data loss.
• Operates across a wide supply voltage range from 2.7 V to 5.5 V for flexible system integration.

Applications

• Industrial automation systems requiring multiple serial ports
• Embedded controllers needing high-speed asynchronous communication
• Telecommunications equipment utilizing multi-channel UART interfaces

Procurement Notes

Verify the exact suffix CPMR against official Texas Instruments documentation to confirm pinout and electrical specifications. Ensure compatibility with existing PCB footprints for the 68-pin PLCC package. Check for any recent product change notices or end-of-life announcements that may affect long-term availability.

Selection Notes

Select this component when four independent UART channels are required in a single package. Compare FIFO depth and maximum data rate against application requirements. Consider the PLCC package constraints if surface-mount density is a priority. Verify voltage level compatibility with the host microcontroller or system bus.

Part Context

This part belongs to the TL16C754 family of quad UARTs. It shares functional similarities with other members like the TL16C754BPNR but differs in packaging and specific suffix designations. The family is designed for applications requiring multiple serial interfaces without occupying excessive board space.

Replacement Considerations

The TL16C754FN is a documented alternative in the same family, offering similar quad UART functionality. Verify pin-to-pin compatibility and electrical parameters before substitution. Other variants may exist; consult official cross-reference guides for confirmed equivalents.
