Athena III combines all of the functionality of a single board computer with a complete analog and digital data acquisition circuit into a single board, offering the most functionality available in a small, compact form factor with fanless wide temperature operation for rugged applications. This 2-in-1 design saves space and increases ruggedness compared to an equivalent 2-board solution.

Athena III is based on the Intel Atom E series processors with memory soldered on board. Standard configuration is 1.0GHz E640T with 1GB memory on board. Configurations up to 1.6GHz E680T with 2GB on-board memory are available as special order.

An enhanced set of I/O ports is provided to support any application’s requirements, including Gigabit Ethernet, SATA, 4 RS-232/422/485 serial ports, 4 USB 2.0 ports, PS/2 keyboard and mouse ports, and legacy parallel port. A watchdog timer programmable for delays up to 2 seconds is also included.

Athena III’s data acquisition circuit is fully backward compatible with Athena II’s. The optional data acquisition circuit provides high-accuracy; stable 16-bit A/D performance with 150KHz sample rate, wide input voltage capability up to +/-10V, and programmable input ranges. It includes 4 12-bit D/A channels, 24 programmable digital I/O lines, and two programmable counter/timers. A/D operation is enhanced by on-board FIFO with interrupt-based transfers, internal/external A/D triggering, and on-board A/D sample rate clock. Placement of the analog circuitry away from the high-speed digital logic ensures low-noise performance for critical applications. All data acquisition features are fully supported by our Universal Driver software for Linux, Windows Embedded Standard 7, Windows CE, and DOS to simplify application development.

The built-in PC/104 expansion bus enables Athena III to work with almost all Diamond Systems’ data acquisition and communications modules, as well as hundreds of I/O boards from other vendors. Athena III can be provided with either stackthrough PC/104 connectors (standard) or non-stackthrough connectors for a slim baseboard application. The compact 4.2″ x 4.5″ form factor, slightly larger than PC/104, enables Athena III to include more features on a single board and still fit inside our Pandora enclosure system.

All Athena III SBCs have a fan-less operating temperature range of -40ºC to +85ºC. Athena III can also be customized for increased ruggedness. Options include latching connectors, hardwired configuration settings, rugged heat sink mounting, conformal coating, and BIOS modifications. Special order options include 1.6GHz E680T CPU, and 2GB of on-board DRAM.
