• 8 or 32 MHz clock
• Optional user clock on board running at different speed than IP bus
• 2 interrupts and 2 slave DMA IP bus lines
• FPGA programmable through bit/byte Blaster header, onboard serial EPROM, or through IP bus
• VITA 4 compliant

Available Software Drivers:

The customer must have an Altera development tool to implement their own FPGA design.

The IP module can be used as a stand-alone module.

The FPGA’s program can be downloaded in one of three ways:

• • • Bit/byte Blaster header connector connected directly to the FPGA
    • Local serial EPROM
    • Through the IP bus

Applications:

The IP-10K50E-PIO can be used as an RS485/RS422 bus I/O interface for parallel and/or serial communications between carrier systems or simply as a TTL I/O subsystem for monitoring and/or controlling digitally oriented functions.

The FPGA can be programmed through the Blaster interface for quick design turnaround. The local serial EPROM can be used for local programming. The FPGA can also be programmed by downloading the entire program into the FPGA from the IP bus for applications that require complete security.
