CHATSWORTH, Calif., 2 March 2008.Aitech Defense Systems Inc. in Chatsworth, Calif., is offering a compact, multi-I/O PCI mezzanine card (PMC), the low-power, single-width M705.
The card has as many as five dual-channel, dual-redundant MIL-STD-1553B channels, 16 ARINC-429 receive channels, and eight ARINC-429 transmit channels, as many as six RS-232/422/485 serial channels and eight opto-isolated digital discrete input channels.
Additional board options include an ARINC 708 weather radar interface contained as VHDL code within the large on-board field-programmable gate array (FPGA).
The card typically consumes less than 7.5 Watts and resists shock and vibration. Applications include tactical avionics platforms such as F/A-18 Hornet strike fighter or V-22 tiltrotor mission computers, as well as mission data recorders.
The MIL-STD-1553 (STANAG 3838) channels support BC/RT/MT operation modes and offer 128 kilobytes (64K words) of dual-port RAM per channel. All ARINC-429 channels comply with the AEEC adoptions of the ARINC-429 specifications and provide high and low speed operation, 100 and 12.5 kilobits per second respectively.
The six UART channels feature a global interrupt source register and two of the channels can provide modem flow control lines (RTS, CTS, DTR and DSR). The discrete input channels serve as general-purpose I/O ports that connect to the GPIO FPGA, but are primarily used to externally assign the RT address to the MIL-STD-1553 channels.
The M705 has a 32-bit/66 MHz PCI 2.2 interface that supports 5- and 3.3-volt PCI universal signaling levels. The conduction-cooled version per ANSI/VITA 20-2001 routes all signals to the rear P4 connector and the IEEE 1386-2001 air-cooled version can be equipped with connectors for front panel I/O signal routing.
The PMC operates in temperatures from -55 to 85 degrees Celsius and with software in rugged and military levels of ruggedization. Software includes a driver package for on-board resources and built in test (BIT), initially through the Wind River VxWorks 5.x and 6.x operating systems.
