| 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
