The MOAB series of boards includes various implementations that address the most commonly found interfaces, ranging from serial asynchronous RS-422 interfaces, to SpaceWire interfaces, to MILSTD-1553 to analog interfaces, including temperature sensors, and voltage and current inputs and outputs. All MOAB boards provide a radiation tolerant Actel RTAX2000S FPGA that is used for managing the board functions, interfacing to the backplane via PCI, and to implement mission specific logic, such as autonomous state-of-health collection and reporting.
Standard and Custom Logic Features
To interface to common telecommand components, a MOAB board may be configured to be compatible with CCSDS, SGLS and other command decoding & telemetry encoding formats. Using these formats, the MOAB board may autonomously decode hardware commands, without the need for a system processor. The large amount of FPGA resource available may be used for mission customer specific processing functions
General Purpose Analog Interfaces
MOAB boards are available with a number of different analog interfaces. Input voltage ranges include +/-10V, 28V, and +/- 5V. Current inputs and outputs are available with configurable voltage and current ranges. MOAB boards feature one or two 12- bit or 14-bit A/D converters with configurable sample rates.
Solid State Memory
The memory on the MOAB boards may include up to a total of 12 GBytes of Flash memory which can be used as-is or configured as 3 GBytes of Triple-Modular-Redundant Flash with voting logic implemented in the MOAB FPGA. Boards may provide 2 MBytes of shared SRAM for general purpose use by the MOAB board or any devices on the cPCI bus.
