Richmond, Calif.Mesa Electronics is offering the MESA 5I23, a general purpose programmable industrial I/O card for the PCI bus.
The 5I23 uses a 400K gate Xilinx FPGA for all logic. The FPGA configuration is downloadable from the PCI bus side, allowing almost any kind of specialized I/O function to be created.
The 5I23 uses three 50 pin connectors with I/O module rack compatible pin-outs and interleaved grounds. Each connector provides 24 I/O bits for a total of 72 programmable I/O bits. All I/O bits are 5V tolerant and can sink 12 mA. Pull-up resistors are provided for all pins so that they may be connected directly to opto-isolators, contacts etc. Bus master and DMA capability allow fast PCI transfer rates. A 48 MHz crystal oscillator provides a reference clock that can be multiplied by the FPGAs DLLs for higher clock speeds.
Several pre-made functions are provided, including a 12 axis host based servo motor controller, a 24 channel quadrature counter, many versions of the SoftDMC motion controller including 4 and 8 axis versions for step motors, brush type servo motors and BLDC servo motors, 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. Four-layer circuit card construction is used to minimize radiated EMI and provide optimum ground and power integrity.
Pricing: $153 in 100-piece quantities.
