PC16550D - Universal Asynchronous Receiver/Transmitter

General Description

The PC16550D device is an improved version of the original 16450 Universal Asynchronous Receiver/Transmitter (UART).

Key Features

  • 1 Capable of Running All Existing 16450 Software.
  • Pin for Pin Compatible With the Existing 16450 Except for CSOUT (24) and NC (29). The Former CSOUT and NC Pins Are TXRDY and RXRDY, Respectively.
  • After Reset, All Registers Are Identical to the 16450 Register Set.
  • In the FIFO(1) Mode Transmitter and Receiver Are Each Buffered With 16 Byte FIFO’s to Reduce the Number of Interrupts Presented to the CPU.
  • Adds or Deletes Standard Asynchronous Communica.
