The SC28L92A1A is a pin and function replacement for the SCC2692 and SC26C92 operating at 3.3 or 5 volts supply with added features and deeper FIFOs. Its configuration on power-up is that of the SC26C92.

• 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

  
  

• 16-bit programmable Counter/Timer

  
  

• Parity, framing, and overrun error detection

  
  

• False start bit detection

  
  

• Line break detection and generation

  
  

• Programmable channel mode

  
  

• Automatic wake-up mode for multi-drop applications

  
  

• Start-end break interrupt/status

  
  

• Detects break which originates in the middle of a character

  
  

• On-chip crystal oscillator

  
  

• Power down mode

  
  

• Receiver time-out mode

  
  

• Single +3.3V or +5V power supply

  
  

• Powers up to emulate SC26C92
