PMC-Parallel-IO
64 IO in one slot

In embedded systems many of the interconnections are made with single ended TTL or CMOS level signals. Depending on the system architecture an IP or a PMC will be the right choice to make the connection. With most architectures you have a choice as there are carriers for cPCI, PCI, VME, PC/104p and other buses for both PMC and IP mezzanine modules. Usually the choice is based on other system constraints as both the PMC and IP can provide the IO you require. Dynamic Engineering would be happy to assist in your decision making regarding architecture and other trade-offs with the PMC / IP decision. Dynamic Engineering has carriers for IP and PMC modules for most architectures, and is adding more as new solutions are requested and required by our customers.

If you are interested in an IP module solution please refer to the IP-Parallel-IO.

The PMC compatible PMC-Parallel-IO has 64 independent digital IO. The high density makes efficient use of precious PMC slot resources. The IO is available for system connection both through the front panel and via the rear [Pn4] connector. A high density 68 pin SCSI III front panel connector provides the front panel IO. The rear panel IO has a PIM and PIM Carrier available for rear panel wiring options. The HDEterm68 can be used as a breakout for the front or rear panel IO. The HDEcabl68 provides a convenient cable.

Each channel is programmable to be input or output on a channel-by-channel basis. Two IO channels can be used as interrupt generators. Interrupts are programmable to be based on level or edge and active high or low. An external clock and clock enable can be used or the internal clock selected for capturing the Input channels. The PCI clock can be divided by several programmable divisors to provide the right sampling rate for your application.

12 of the IO are routed through the Altera device [EPM7128] to allow for custom applications that require hardware intervention or specific timing. The Altera can be programmed via the convenient header and programming adapter. Please contact Dynamic Engineering for the development kit which includes the base design to allow for easy modifications to the hardware implementation. Dynamic Engineering can make the design changes for you if that is more convenient.

The registers are mapped as 32 bit words and support byte, word and 32 bit access. All registers are read-writeable. The Windows® compatible [XP/2000] driver is available to provide the system level interface for this design. Use standard C/C++ to control your hardware or use the Hardware manual to make your own software interface. The hardware manual is downloadable from the bottom of this page. The software manual is also available on-line.

    		•  64 independent channels. Each channel can be an input or an output.

  • Pull-up Resistor
    		•  470 standard, 1K, 4.7K available.

  • Sink Current
    		•  64+ mA per channel

  • Cable interface
    		•  Industry standard SCSI III front panel IO and Pn4 backplane connection.

  • Software Interface
    		•  2 - 32 bit registers mapped to the 64 IO channels. Byte, Word, Long writeable. Read-back of channel control registers and input registers. Read-write of control register for card configuration.

  • Interrupts
    		•  IO Channels 0,1 can be programmed to cause interrupts. Each channel is programmable to be masked, active hi, active low, edge triggered. Interrupts are mapped to INTA on PCI bus.

  • Power Requirement
    		•  +5V only.

  • Protection
    		•  All IO Channels are protected with Transorbs, and current limiting resistors.

  • External Clock
    		•  Input registers are programmable to capture data on the internal clock or external user supplied clock. Additionally an external clock enable input is provided to allow selective clocks to be gated at the register. SW can select internal or external source for clock and clock enable.

  • Internal Clock
    		•  The Input registers can be clocked with an internally generated clock derived from the PCI reference. The rate is programmable with ~8 MHz, 4, 2, 1, 500KHz, 250, 125, 64 selectable based on a 33 Mhz. PCI clock.

  • Control Bits
    		•  The upper 12 control bits are routed through the FPGA to allow for custom state-machine implementations.



    PMC-Parallel-IO Benefits

  • Speed
    		•  The PMC-Parallel-IO is a software controlled HW interface. As fast as the PCI interface can push the data across, the outputs can change. With the Windows® driver several accesses per microsecond can be achieved. Your time to market will be shortened by the easy to use interface, flexability in design, and off-the-shelf availability.

  • Price
    		•  The PMC-Parallel-IO has a low price point, and low integration cost for a low system cost. The PMC Parallel IO has an associated PIM and PIM Carrier which can lead to further savings in cPCI environments.

  • Ease of Use
    		•  The PMC-Parallel-IO is easy to use. A point and shoot user interface to the IO. Please download the manual and see for yourself. The engineering kit provides a good starting point for a new user. 64 bits of user defined IO without the usual handicap of byte, word or other configuration boundaries for the data.

  • Availability
    		•  The PMC-Parallel-IO is a popular board. We keep the PMC-Parallel-IO in stock. Send in your order and in most cases have your hardware the next day - delivered to you via FedEx. Custom versions can be dialed in quickly as well as customer requested VHDL features. The PMC-Parallel-IO is one of our more frequently scheduled boards. Consider using scheduling on your next order.

  • Size
    		•  The PMC-Parallel-IO is a standard single wide PMC [single slot] board which conforms to the PMC mechanical and electrical specifications. Eliminate mechanical interference issues.

  • PMC Compatibility
    		•  The PMC-Parallel-IO is PMC compliant per the IEEE 1386 specification.

  • PCI Compatibility
    		•  The PMC-Parallel-IO is PCI compliant. You can develop with a PCI to PMC adapter - PCI2PMC or PCIBPMC.
