The PMD10K100 is designed as one kind of PMC device that provides eight asynchronous serial communication ports from a single PMC carrier slot. And this device has three points of benefits:(1)High-density design lowers per-port costs and saves PMC carrier card slots for other functions; (2)64-byte FIFO buffers minimize CPU interaction for improved system performance; (3)Each serial channel provides handshake support to simplify interfacing with modems.
Features of the PMD10K100 are:(1)Eight RS232E ports; (2)64-byte transmit FIFO buffers 64-byte receive FIFO buffers; (3)Programmable baud rate (up to 120Kbps); (4)Individual handshake lines (RTS, CTS) on each channel; (5)Line-break and false start-bit detection; (6)Industry-standard software-compatible 16C550 configuration registers.
The absolute maximum ratings of the PMD10K100 can be summarized as:(1)Configuration: Independent, non-isolated serial ports with a common single return connection and configured as a DTE device.; (2)Data rate: Programmable up to 120K bits/second using internal baud rate generator.; (3)Max. cable length: 15 meters (50 feet) typical, limited to a cable capacitive load of 2500pF.; (4)Character size: 5 to 8 bits, software-programmable.; (5)Parity: Odd, even, or no parity; software-programmable.; (6)Stop bits: 1, 1-1/2, or 2 bits; software-programmable.; (7)Data register buffers: Double buffered or 64-byte FIFO buffered,mode selectable.
