The PC104-72A is an PC/104 based Digital I/O Board. Each board uses three industry-standard Programmable Peripheral Interface chips (PPI) to achieve 72 channels of digital I/O. Advanced features are implemented on this board, making it ideal for industrial and control applications. Most features are software controlled which eliminates the need for a change in jumper settings. Port C0 and C3 of each PPI are tagged to a global interrupt sharing line. This makes it ideal for Multi-tasking Environments where host CPU overhead must be kept to a minimum. Only a level change on any of these Port Lines will generate an interrupt.

Wait-State Generation is incorporated in the PC104-72A for operation on CPU modules with fast Bus Clock speeds. It is fully PC104 Rev 2.3 compliant and compatible with the ISA based Digital/IO Boards allowing easy migration from ISA to the PC104 Based PC104-72A. The PC104-72A utilizes SMT and high-density logic (FPGA) design for its operation and interface to the PC104 Bus.

The PC104-72A offers optimal performance under DOS, Win95/98 and Win NT. This ensures that most key features can be controlled from software. Data transfers through the PC104 Bus can exceed 50kBytes/S which means that host CPU overhead is kept to a minimum. The PC104-72A is an advanced 72 Digital I/O Board for PC104 based systems.
