SC28L92 Features

• Member of IMPACT family: 3.3 to 5.0 volt , -40°C to +85°C and 68K for 80xxx bus interface for all devices.
• Dual full-duplex independent asynchronous receiver/transmitters
• 16 character FIFOs for each receiver and transmitter
• Pin programming selects 68K or 80xxx bus interface
• 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:
  • 28 fixed rates: 50 to 230.4k baud
  • Other baud rates to MHz 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 loop back
  • Remote loop back
  • Multi-drop mode (also called ?wake-up? or ?9-bit?)
• Multi-function 7-bit input port (includes IACKN)
  • Can serve as clock or control inputs
  • Change of state detection on four inputs
  • Inputs have typically >100k pull-up resistors
  • Change of state detectors for modem control
• Multi-function 8-bit output port
  • Individual bit set/reset capability
  • Outputs can be programmed to be status/interrupt signals
  • FIFO status for DMA 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 interrupt outputs that may be wire ORed.
  • Each FIFO can be programmed for four different interrupt levels
  • Watch dog timer for each receiver
• Maximum data transfer ra
