PMC520: Serial Communication, 232 Octal Description
These modules provide eight asynchronous serial communication ports from a single PMC Socket. 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.
Specifications
RS232E Serial Ports
Configuration: Independent, non-isolated serial ports with a common single return connection and configured as a DTE device.
Data rate: Programmable up to 120K bits/second using internal baud rate generator.
Max. cable length: 15 meters (50 feet) typical, limited to a cable capacitive load of 2500pF.
Character size: 5 to 8 bits, software-programmable.
Parity: Odd, even, or no parity; software-programmable.
Stop bits: 1, 1-1/2, or 2 bits; software-programmable.
Data register buffers: Double buffered or 64-byte FIFO buffered, mode selectable.
Interrupts: Receiver line status (overrun, parity, framing error, or break interrupt); received data available. (FIFO level reached) or character time-out; transmitter
(FIFO level reached); or modem status (CTS).
Environmental
Operating temperature: 0 to 70°C (PMC520-64) or -40 to 85°C (PMC520-64E).
Storage temperature: -55 to 125°C.
Relative humidity: 5 to 95% non-condensing.
Power: +5V (±5%), consult factory for current specifications.
MTBF: 2,848,670 hrs at 25°C, MIL-HDBK-217F, notice 2.
PMC Compliance
Conforms to PCI Local Bus Specification, Revision 2.3 and CMC/PMC Specification, P1386.1.
4K Memory Space Required: One Base Address Register.
Signaling: 3.3V and 5V compliant.

Tech Papers
What are PMC and XMC Modular I/O Standards? - 8401066PMC and XMC Modular I/O – Established Standards in High Performance Systems The IEEE standard for PCI Mezzanine Cards (PMCs) initiated the first successful approach to truly modular I/O devices. Subsequent development has presented system integrators with the XMC modules, introducing support for switched interconnect protocols, adding contacts serial lanes for high-speed data transfer, and providing better... -
