TL16C2752FN

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C2752FN is a dual universal asynchronous receiver and transmitter (UART) manufactured by Texas Instruments in a 44-pin PLCC package. It operates with supply voltages ranging from 1.8 V to 5.5 V and supports data rates up to 3 Mbps at 5 V nominal, or up to 1.5 Mbps at 3.3 V nominal. Each UART channel includes independent 64-byte transmit and receive FIFOs. The device features programmable auto-RTS and auto-CTS hardware flow control, embedded IrDA encoding/decoding, RS-485 transceiver controls, and software flow control modes. It maintains pinout and software compatibility with the TL16C450.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product folder to confirm package type and temperature range. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the datasheet revision date to confirm the accuracy of electrical characteristics before finalizing procurement specifications.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a design requires two independent serial interfaces with high-speed data buffering capabilities. The 64-byte FIFOs significantly reduce CPU overhead compared to standard UARTs. Verify that the system clock frequency supports the desired baud rate generation divisors. Ensure the operating voltage matches the target logic levels, as the device supports multiple voltage domains from 1.8 V to 5.5 V.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

The TL16C2752 serves as a functional upgrade to the TL16C2552, offering larger FIFOs and enhanced flow control features while maintaining backward compatibility with existing software drivers designed for the TL16C450. It belongs to the Texas Instruments ACE family of asynchronous communication elements, providing robust serial connectivity solutions for embedded systems requiring reliable data transmission.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C2552 is a compatible predecessor with identical pinouts but smaller 16-byte FIFOs. Designs migrating from the TL16C2552 can utilize the TL16C2752 without hardware changes, accessing extended features through the enhanced feature register.
