Octal UART with RS-232 and RS-485 interfaces

PSCC –1028 is an octal asynchronous serial communication controller based on a PMC form factor.

The PSCC-1028 module is compatible with the PCI specification 2.2 and run on 32-bit bus size at 33 MHz frequency. Data transfers operation can be formatted in 8-bit, 16-bit, 24-bit or 32-bit wide.

The PSCC-1028 provides 8 enhanced 16C550 (5th gen) UARTs with the PCI Bus interface. Half and full duplex mode are supported with RS-485 interface for point-to-point and multi-drop bus configuration..

Each UART has its own 64 Byte of transmit and receive FIFO, a set of 16C550 compatible control and status registers, and a baud rate generator for individual channel data rate setting.

All channels are available on front panel (SCSI 68-pin connector) and on rear I/O connector (P4).


Electrical interface is selected under software control. The PSCC-1028 can running on major real-time operating systems and with the open-source Linux™ or VxWorks operating systems.
