Features & Applications
The SC28L92A1B,557 is a pin and function replacement for the SCC2692 and SC26C92 operating at 3.3 V or 5 V supply with added features and deeper FIFOs. Its configuration on power-up is that of the SC26C92.
 
Its differences from the SCC2692 and SC26C92 are: 16 character receiver, 16 character transmit FIFOs, watchdog timer for each receiver, mode register 0 is added, extended baud rate and overall faster speeds, programmable receiver and transmitter interrupts. 

The Pin programming will allow the device to operate with either the Motorola or Intel bus interface. The bit 3 of the MR0A register allows the device to operate in an 8 byte FIFO mode if strict compliance with the SC26C92 FIFO structure is required.

Features:

  • Member of IMPACT family: 3.3 V to 5.0 V, -40 °C to +85 °C and 68xxx or 80xxx bus interface for all devices
  • Dual full-duplex independent asynchronous receiver/transmitters
  • 16 character FIFOs for each receiver and transmitter
  • Pin programming selects 68xxx or 80xxx bus interface
  • Parity, framing, and overrun error detection
  • False start bit detection
  • Line break detection and generation
  • Maximum data transfer rates 1x - 1 Mbit/s, 16x - 1 Mbit/s
  • 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 3.3 V or 5 V power supply
  • Powers up to emulate SC26C92
