Summary:
Dynamic Engineering has a multitude of solutions covering different architectures and mezzanine types.

Most systems need TTL lines and in some cases a lot of them. The PMC Parallel TTL packs 64 TTL IO with Change Of State COS processing, programmable interrupts, integrated PCI interface with DMA capability, multiple clocking options and room to add new features within the FPGA into a PMC module. For systems requiring more than 64 lines the DIP Switch can be used to facilitate multiple cards with unique settings. Options include: front, rear or dual IO , extended temperature, conformal coating, 3V or 5V IO, and transorb protection. The PMC Parallel TTL is an upgrade for the PMC Parallel IO design. It is recommended for new system implementations. Available now.

Does your system require single ended TTL or CMOS level signals? Dynamic Engineering has a multitude of solutions covering different architectures and mezzanine types. With most architectures you have a choice with carriers for cPCI, PCI, VME, PCI-104, and other buses for both PMC and IP mezzanine modules. Usually your choice is based on other system constraints as both the PMC and IP can provide the IO you require. Dynamic Engineering can assist in your decision making regarding architecture and other trade-offs.

The PMC compatible PMC-Parallel-TTL 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. The pin definitions are consistent with the PMC Parallel IO card to enable users of the PMC Parallel IO to migrate to the PMC Parallel TTL quickly and easily.

Each IO is independently programmable. The outputs can be enabled and driven high or low. When disabled on-board pull-ups terminate the lines. The pull-ups can be referenced to 5V or 3.3V as an ordering option. A master enable is available to allow the user to synchronize the upper and lower outputs for coherant 64 bit operation in a 32 bit system. The master enable can be set to allow independent upper and lower bank updates.

All channels can be read as inputs regardless of the transmit enable programming. Local loop-back can be used for BIT. All IO channels can be used as interrupt generators. Interrupts are programmable to be based on either or both edges for Change of State operation. An external clock, PCI clock, or oscillator can be selected for the reference on the COS operation. The reference can be programmed to be divided to create lower frequencies. An optional PLL is available to support user frequency selection to provide the right sampling rate for your application.

All of the IO are routed through the FPGA device to allow for custom applications that require hardware intervention or specific timing. For example the design of the PMC Parallel TTL supports internal FIFO´s and DMA. With an added state-machine for your interface the hardware can provide much more than a simple parallel interface. Contact Dynamic Engineering for convenient customer specific implementations.

The base model has a simple to use register based interface. The registers are mapped as 32 bit words. 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.

Hardware is readily available for overnight delivery. Order yours today!
