Product Details

Features

  • Dual full-duplex independent asynchronous receiver/transmitters
  • 8 character FIFOs for each receiver and transmitter
  • Programmable data format
    • 5 to 8 data bits plus parity
    • Odd, even, no parity or force parity
    • 1, 1.5 or 2 stop bits programmable in 1/16-bit increments
  • 16-bit programmable Counter/Timer
  • Programmable baud rate for each receiver and transmitter selectable from:
    • 27 fixed rates: 50 to 230.4k baud
    • Other baud rates to 230.4k baud at 16X
    • Programmable user-defined rates derived from a programmable counter/timer
    • External 1X or 16X clock
  • Parity, framing, and overrun error detection
  • False start bit detection
  • Line break detection and generation
  • Programmable channel mode
    • Normal (full-duplex)
    • Automatic echo
    • Local loopback
    • Remote loopback
    • Multidrop mode (also called ?wake-up? or ?9-bit?)
  • Multi-function 7-bit input port
    • Can serve as clock, modem, or control inputs
    • Change of state detection on four inputs
    • Inputs have typically >100k pull-up resistors
  • Multi-function 8-bit output port
    • Individual bit set/reset capability
    • Outputs can be programmed to be status/interrupt signals
    • FIFO states for DMA and modem interface
  • Versatile interrupt system
    • Single interrupt output with eight maskable interrupting conditions
    • Output port can be configured to provide a total of up to six separate wire-ORable interrupt outputs
    • Each FIFO can be programmed for four different interrupt levels
    • Watch dog timer for each receiver
  • Maximum data transfer rates: 1X - 1Mb/sec, 16X - 1Mb/sec
  • Automatic wake-up mode for multidrop applications
  • Start-end break interrupt/status
  • Detects break which originates in the middle of a character
  • On-chip crystal oscillator
  • Power down mode
  • Receiver timeout mode
  • Single +5V power supply
  • Powers up to emulate SCC2692
