The HERON-IO5 provides a user programmable FPGA along with fast Analog Inputs and outputs for a HERON system. The FPGA controls the sampling of the A/Ds and D/As. The incoming digitised data is then fed to the FPGA where it can be processed, buffered or simply written to a HERON FIFO for use in the rest of the system. The outgoing digitised data is then fed from the FPGA where it can be processed, buffered or simply read from a HERON FIFO.

Using the HERON serial bus allows the FPGA to be configured with a standard module configuration, or a custom one provided by the user or HUNT ENGINEERING. After configuration the module can accept user messages over the HERON serial bus, allowing registers etc to be programmed. If a more significant programming change is required a complete new FPGA configuration can be downloaded. The FLASH based configuration PROM can load the configuration data into the FPGA when it is used in an embedded system This PROM can be programmed using the standard JTAG cable available from Xilinx (such as Xilinx^Ž Parallel cable 4 or USB-JTAG cable).

The Digital I/O has a number of voltage formats such as LVTTL or LVCMOS defined by the configuration downloaded to the FPGA.

The HERON-IO5 can access HERON-FIFOs at a rate of 32 bits per FIFO clock in AND 32 bits per FIFO clock out concurrently. For example with a FIFO clock of 100Mhz this is 400Mbytes/sec in AND 400Mbytes/sec out.

The use of a Virtex^Ž-II XC2V**fg676-6 part allows clock rates of up to 365Mhz, and also provides hard coded multipliers and extended I/O formats such as Low Voltage Differential Signalling (LVDS)
NOTE: Virtex II I/Os are not 5v tolerant!
