This device is commonly used in embedded systems, industrial automation, and communication interfaces.

Application Scenarios & Design Considerations

ASYNCHRONOUS COMMUNICATIONS ELEMENT WITH AUTOFLOW CONTROL

Alternative Part Number

  • ST16C550CQ48 --: Pin-compatible UART with 16-byte FIFO in the same 48-pin TQFP package; widely used as a direct TL16C550 replacement with equivalent register set.
  • XR16C550CQ48 --: Drop-in compatible 16C550-class UART in 48-pin TQFP, same FIFO depth and register map, suitable substitute for the TL16C550CPFB.
  • PC16550DV --: Classic 16550 UART from the same vendor with compatible register interface and FIFO; requires package/board adaptation but is a proven functional alternative.
