Features

  • 2 channel UART
  • 5 V, 3.3 V and 2.5 V operation
  • 5 V tolerant inputs
  • Industrial temperature range (-40 Cel. to +85 Cel.)
  • Pin and functionally compatible to 16C2450 in LQFP48 package, and software compatible with industry standard 16C450, 16C550, and SC16C650
  • Up to 5 Mbit/s data rate at 5 V and 3.3 V, and 3 Mbit/s at 2.5 V
  • 32-byte transmit FIFO to reduce the bandwidth requirement of the external CPU
  • 32-byte receive FIFO with error flags to reduce the bandwidth requirement of the external CPU
  • Independent transmit and receive UART control
  • Four selectable Receive and Transmit FIFO interrupt trigger levels
  • Automatic software (Xon/Xoff) and hardware (RTS/CTS) flow control
  • Programmable Xon/Xoff characters
  • Software selectable baud rate generator
  • Standard modem interface or infrared IrDA encoder/decoder interface
  • Supports IrDA version 1.0 (up to 115.2 kbit/s)
  • Sleep mode
  • Standard asynchronous error and framing bits (Start, Stop, and Parity Overrun Break)
  • Transmit, Receive, Line Status, and Data Set interrupts independently controlled
  • Fully programmable character formatting:
    • 5-bit, 6-bit, 7-bit, or 8-bit characters
    • Even, odd, or no-parity formats
    • 1, 1 1/2, or 2-stop bit
    • Baud generation (DC to 5 Mbit/s)
  • False start-bit detection
  • Complete status reporting capabilities
  • 3-state output TTL drive capabilities for bi-directional data bus and control bus
  • Line break generation and detection
  • Internal diagnostic capabilities:
    • Loop-back controls for communications link fault isolation
  • Prioritized interrupt system controls
  • Modem control functions (CTS, RTS, DSR, DTR, RI, CD)
