5I20 FPGA based PCI Anything I/O card
The MESA 5I20 is a general purpose programmable I/O card for the PCI
bus. The 5I20 uses a 200K gate Xilinx FPGA for all logic, so it is
truly an Anything I/O card. The FPGA is down loadable from the PCI bus
side, allowing creation of almost any kind of specialized I/O function,
even including micro-controllers in the FPGA. Several pre-made
functions are provided, including a 12 channel host based servo motor
controller, a 4 or 8 channel micro-controller based servo motor
controller (SoftDMC), and a 8 channel, 32 bit timer counter card capable
of running at 100 MHz. VHDL source is provided for all examples. All
I/O bits are 5V tolerant and can sink 24 mA. Pullup resistors are
provided for all pins so that they may be connected directly to
opto-isolators, contacts etc. The 5I20 has 72 I/O bits available on
three 50 pin connectors, all connectors use I/O module rack compatible
pin outs. Several I/O interface daughter cards are available for the
5I20. 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.
