Multi-channel serial communication controller card
ACTIS Computer
This module provides eight synchronous or asynchronous full-duplex channels, with an independent Transmitter/ Receiver baud rate generator for each channel. Two types of interface are supported by the UCC-08 modules:
* UCC-08A: RS-232D interface.
* UCC-08B: RS-422/RS-485 interface.
The UCC-08A provides all the modem signals (TxD, RxD, RTS, CTS, DTR,and DCD) for the RS-232D interface. The UCC-08B with RS-422/RS-485 interfaces allows multi-drop capabilities with collision detection, and provides the TxD±, RxD±, TxC± and RxC± signals.
The UCC-08 module is based on a high performance single chip octal USART, which provides a very large FIFO to minimize the receiver overrun or the interrupt overhead (64-Byte receiver and 64-Byte transmitter FIFOs for each channel).
