TL16C752BPTR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C752BPTR is a dual universal asynchronous receiver/transmitter (UART) manufactured by Texas Instruments. It features two independent UART channels, each equipped with a 64-byte transmit FIFO and a 64-byte receive FIFO. 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 with a voltage range of 2.7 V to 3.6 V. The component is housed in a 48-pin LQFP package and is supplied in a reel format.

UARTs (Universal Asynchronous Receiver Transmitter) Procurement Notes

Verify the specific ordering suffix 'PTR' confirms the reel packaging format as indicated in the product description. Ensure the 3.3-V operating voltage aligns with the target system's power rails. Confirm the 48-pin LQFP footprint matches the PCB design constraints before finalizing procurement orders.

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 logic systems. It serves as a pin-compatible alternative to legacy ST16C2550 devices while offering enhanced features such as programmable sleep modes and advanced flow control options for optimized system performance.

UARTs (Universal Asynchronous Receiver Transmitter) Part Context

This part belongs to the TL16C752B family of dual UARTs from Texas Instruments. It shares functional similarities with other members like the TL16C752BTPTREP but differs in packaging and delivery format. The series is designed for applications needing robust serial communication interfaces with high data throughput capabilities.

UARTs (Universal Asynchronous Receiver Transmitter) Replacement Considerations

The TL16C752BPTR is pin-compatible with the ST16C2550. Other Texas Instruments alternatives within the same family include the TL16C752BLPTREP and TL16C752BTPTREP, which offer identical functionality but may vary in package type or shipping configuration.

UARTs (Universal Asynchronous Receiver Transmitter) FAQ

What is the maximum baud rate supported by the TL16C752BPTR?

The device supports baud 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.

How does the hardware flow control function operate?

Hardware flow control utilizes auto-CTS and auto-RTS functions. Auto-CTS prevents transmission if the CTS signal is inactive, while auto-RTS controls the RTS output based on RX FIFO trigger levels programmed in the TCR to prevent overrun errors.

Can the TL16C752BPTR be used in low-power applications?

Yes, it includes a programmable sleep mode that stops the UART clock and baud rate clock when idle, significantly reducing power consumption until activity is detected on the RX line or modem pins.
