| MESA releases 5I23 I/O card for the PCI bus | ||
|
||
 The MESA 5I23 is a general purpose programmable industrial I/O card for the PCI bus. The 5I22 uses a 400K gate Xilinx 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 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 which 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. Price of the 5I23 is $153 in 100's. |
