SPARTAN 6 FPGA based simple SPI Interface based Industrial grade 8 Channel Leak Detection IO Cards communicating to the CPU Cards via the Back Plane Card for Nuclear process instrumentation.

Following are the main features of the product :-

• Channel to Channel isolation for all the 8 channels 
• All the analog input channels are isolated from the FPGA using 5KV digital isolators.
• Half of the analog inputs processed using 12 bit ADC – AD7091
• Half of the remaining analog inputs processed using precision comparators – ADCMP396 and multiplexers - ADG1604BCPZ
• All the analog input channels transient and over voltage protected.
• On board Voltage monitoring and Temperature circuitry and hardware watchdog timer for fail safe operation under board failure condition.
• Supervisory reset circuitry - MAX16060D
• FPGA healthiness monitored.
• Online diagnostics using voltage reference outputs
• Level translator circuitry between FPGA and the backplane interface - 74ALVC164245DGG_11 
• Simple Hot-Swap Controller based Design.
• Fan-Less design.
• SI, PI, Thermal Analysis done.
