l
Member of IMPACT family: 3.3 to 5.0 volt, -40°C to +85°C and 68K for 80xxx bus interface for all devices.
l
Dual full-duplex independent asynchronous receiver/transmitters
l
16 character FIFOs for each receiver and transmitter
l
Pin programming selects 68K or 80xxx bus interface
l
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
l
16-bit programmable Counter/Timer
l
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
l
Parity, framing, and overrun error detection
l
False start bit detection
l
Line break detection and generation
l
Programmable channel mode
Normal (full-duplex)
Automatic echo
Local loop back
Remote loop back
Multi-drop mode (also called ‘wake-up’ or ‘9-bit’)
l
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
