TL16C752BPTG4

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C752BPTG4 is a dual universal asynchronous receiver/transmitter (UART) manufactured by Texas Instruments. It features two independent UART channels, each equipped with 64-byte transmit and receive FIFOs. The device supports data rates up to 3 Mbps when using a pulse width oscillator or clock source with a 48-MHz input clock, and up to 1.5 Mbps with a crystal function at a 24-MHz input clock. It operates on a single 3.3-V power supply and utilizes a 48-pin PT (LQFP) package.

UARTs (Universal Asynchronous Receiver Transmitter) Feature Summary

• Dual UART architecture with integrated 64-byte FIFOs for both transmission and reception
• Supports software and hardware flow control including programmable Xon/Xoff characters and auto-RTS/CTS
• Programmable baud rate generator with selectable trigger levels for DMA and interrupt generation
• Includes internal loopback capability for onboard diagnostics and prioritized interrupt system

UARTs (Universal Asynchronous Receiver Transmitter) Applications

• Industrial communication systems requiring high-speed serial data transfer
• Embedded controllers needing multiple asynchronous serial ports
• Modem interface applications with hardware flow control requirements

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature range. Confirm RoHS compliance status as per the latest datasheet revision. Check for any product discontinuance notifications or alternative part recommendations from Texas Instruments before finalizing procurement plans.

UARTs (Universal Asynchronous Receiver Transmitter) Selection Notes

Select this component when a dual-channel UART solution with substantial buffering is required for 3.3-V systems. Ensure the application can accommodate the 48-pin LQFP footprint. Verify that the host processor supports the necessary address decoding for the three address lines and provides adequate clock signals for the desired baud rate generation capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This component belongs to the TL16C752B family of dual UARTs. It is pin-compatible with the ST16C2550 but offers enhanced features such as larger FIFOs and advanced flow control options. The 'PT' suffix indicates the 48-lead thin quad flatpack package, while 'TG4' typically denotes lead-free and RoHS-compliant manufacturing processes.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C752B is designed to be pin-compatible with the ST16C2550. For direct replacements within the Texas Instruments portfolio, consider the TL16C752D or other variants in the same series, ensuring voltage and package compatibility.
