TL16C2752IFNR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C2752IFNR is a dual universal asynchronous receiver and transmitter (UART) manufactured by Texas Instruments. It operates with supply voltages ranging from 1.62 V to 5.5 V. The device features two independent UART channels, each equipped with 64-byte transmit and receive FIFOs. It supports baud rates up to 3 Mbps at 5 V nominal and includes programmable auto-RTS and auto-CTS hardware flow control. The IFNR suffix indicates the part is supplied in a tape and reel packaging format.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify that the ordering suffix 'R' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm the specific temperature grade associated with the 'I' suffix matches the operational environmental requirements of the target design before finalizing procurement orders.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when migrating from legacy TL16C2552 designs to benefit from larger 64-byte FIFOs and enhanced flow control features. Ensure the system clock frequency supports the desired baud rate generation. Verify that the 44-pin PLCC package footprint aligns with the existing PCB layout constraints.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This device serves as a functional upgrade to the TL16C2552, maintaining pinout and software compatibility while offering increased throughput capabilities. It provides an extended register set to access advanced features such as embedded IrDA support and programmable interrupt thresholds, facilitating easier integration into modern serial communication systems.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C2552 is a pinout-compatible predecessor. Designers migrating from older UART implementations should verify that the extended register configurations do not conflict with existing initialization routines.
