• 4I68-4 FPGA based PC104-PLUS Anything I/O card

The MESA 4I68 is a general purpose programmable I/O card for the PCI bus. The 4I68 uses a 400K gate Xilinx Spartan3 FPGA for all logic, so it is truly an  Anything I/O  card.  The FPGA configuration is downloadable from the PCI bus side, allowing creation of almost any kind of specialized I/O function.  The 4I68 uses a bus mastering PCI bridge to give the card the ability to work with both 5V and 3.3V PCI buses and support high FPGA/PCI bus transfer rates.  Several pre-made functions are provided, including a 12 axis host based servo motor controller, a 24 channel quadrature counter, an 8 axis micro-controller based servo motor controller (SoftDMC), a simple 72 bit parallel I/O port, and a 12 channel, 32 bit timer counter card capable of running at 100 MHz. VHDL source is provided for all functions.  
The 4I68 uses three 50 pin connectors with I/O module rack compatible pin-outs and interleaved grounds. Two of the connectors support single ended 3.3V signals. One connector supports 3.3V or 2.5V signals and LVDS. DCI termination is supported on all I/O pins.  Each connector provides 24 I/O bits for a total of 72 programmable I/O bits.  A 50 Mhz crystal oscillator provides a reference clock which can be multiplied by the FPGAs DLLs for higher clock speeds. Several I/O interface daughter cards are available for the 4I68.  These cards include a 4 axis 3A Hbridge, a 2 Axis 3A stepper motor driver, an analog servo amp. interface, an RS-422/485 interface, and a debug LED card.
