PMC520

Octal Serial 232

Communication

These modules provide eight asynchronous serial

communication ports from a single PMC carrier slot.

Software-configuration helps you quickly set baud rates,

character-sizes,stop bits,and parity. Signal support for

RTS/CTS handshaking is also included.

For more efficient data processing,each serial port is

equipped with 64-character FIFO buffers on the

transmit and receive lines.

The data ports generate individually controlled transmit,

receive,line status,and data set interrupts. A global

interrupt source register provides interrupt status

indication for all eight channels to speed up interrupt

parsing.

Eight RS232E ports

64-byte transmit FIFO buffers

64-byte receive FIFO buffers

Programmable baud rate (up to 120Kbps)

Individual handshake lines (RTS,CTS)

on each channel

Line-break and false start-bit detection

Industry-standard software-compatible 16C550

configuration registers

High-density design lowers per-port costs and

saves PMC carrier card slots for other functions.

64-byte FIFO buffers minimize CPU interaction for

improved system performance.

Each serial channel provides handshake support to

simplify interfacing with modems.

With eight serial ports per module, the PMC520 provides a high-density solution to reduce costs and use fewer card slots.
