Application Scenarios & Design Considerations

2.97V TO 5.5V DUART WITH 16-BYTE FIFO

Alternative Part Number

  • ST16C2550IQ48 --: MaxLinear (formerly Exar) dual UART in the same 16C2550 family with compatible register set and pinout, direct functional replacement.
  • TL16C2550IPFB --: TI dual-channel UART with 16-byte FIFOs, functionally equivalent to the XR16C2550 and widely available in TQFP package.
  • SC16C2550BIB48 --: NXP dual UART with 16-byte FIFOs offering similar feature set and interface, suitable drop-in alternative with minor pin review.
  • TL16C2550PFB --: Dual-channel UART with compatible register set and FIFO architecture, well-documented and readily sourced from TI.
