常見問題解答

What is TL16C754BFN?

The TL16C754BFN is a quad UART (Universal Asynchronous Receiver/Transmitter) with 64-byte FIFO (First In, First Out) designed by Texas Instruments. It is ideal for applications requiring multiple serial communication channels, such as industrial automation, telecommunications, and data acquisition systems.

How Does TL16C754BFN Work?

The TL16C754BFN works by providing four independent UART channels with 64-byte FIFOs for efficient data buffering and transfer. It supports asynchronous data communication with programmable baud rates and features advanced UART functionality such as modem control signals and adjustable TX and RX FIFO trigger levels.

How Many Pins does TL16C754BFN have and What are the Functions of the Pinout Configuration?

The TL16C754BFN is housed in a 100-pin LQFP (Low-Profile Quad Flat Package) package. The pinout configuration includes:

  • VCC: Power supply pin.
  • GND: Ground pin.
  • TXD0-3: Transmit data pins for channels 0 to 3.
  • RXD0-3: Receive data pins for channels 0 to 3.
  • RTS0-3: Request to Send pins for channels 0 to 3.
  • CTS0-3: Clear to Send pins for channels 0 to 3.
  • IRQ: Interrupt request output pin.
  • REFCLK: Reference clock input pin.
  • RESET: Reset input pin.

What are the Pros and Cons of TL16C754BFN?

Pros:

  • Quad UART: Provides four independent UART channels, offering versatility in serial communication applications.
  • 64-Byte FIFO: Features a 64-byte FIFO for each channel to efficiently handle data buffering and reduce CPU overhead.
  • Programmable Baud Rates: Supports programmable baud rates for flexible data transfer speeds.
  • Advanced Functionality: Includes modem control signals and adjustable FIFO trigger levels for enhanced UART operation.
  • Wide Temperature Range: Operates over a wide temperature range, suitable for industrial and automotive applications.

Cons:

  • Complex Setup: Configuration of multiple UART channels and FIFO settings may require careful design consideration.
  • Package Size: The 100-pin LQFP package may not be suitable for space-constrained designs.
  • Power Consumption: May consume more power compared to single UART devices due to multiple channels and FIFOs.

Are There Any Equivalents/Alternatives to TL16C754BFN for Recommendation?

  • The ST16C654 from Exar Corporation is a similar quad UART with 64-byte FIFO.
  • Alternatives to the TL16C754BFN include the XR16M564 from Exar Corporation and the 16C1050 from NXP Semiconductors.
