• Increased reliability
 The Athena II SBC from Diamond Systems combines the low-power,
highly integrated VIA Mark CoreFusion™ processor with on-board
memory and data acquisition into a new compact form factor measuring
only 4.2" x 4.5". The result is a small, low-heat-dissipation,
and extremely rugged embedded CPU that fits in tight spaces and survives
harsh environments. On-board 256MB RAM, LCD+CRT video, AC97 audio, 4
USB ports, 4 serial ports, a 16-bit low-noise data acquisition circuit,
and extended temperature operation make Athena II an all-in-one, complete
embedded solution for demanding applications.
Athena II can be customized
for increased ruggedness. Options include latching connectors, hardwired
configuration settings, rugged heat sink
mounting, conformal coating, and BIOS modifications.
An enhanced set of
I/O ports is provided to support any application's requirements, including
10/100Mbps Ethernet, UDMA-33 IDE, parallel port,
PS/2 keyboard and mouse ports, and 4 USB 1.1 ports. The board also
has 4 16450-compatible RS-232 serial ports. The watchdog timer provides
protection
from software crashes and is programmable for delays up to 2 seconds.
The
built-in PC/104 expansion bus enables Athena II to work with almost all
Diamond Systems data acquisition and communications modules, as well
as hundreds of I/O boards from other vendors. The board can be provided
with either stackthrough PC/104 connectors (standard) or non-stackthrough
connectors for a slim baseboard application. The new compact 4.2" x
4.5" form factor, slightly larger than PC/104, enables Athena II
to include more features on a single board and still fit inside our Pandora
enclosure system.
All Athena II SBCs have a fan-less operating temperature
range of -40ºC
to +85ºC except models ATHM800256NLP and ATHM800256ALP which have
a fan-less operating temperature range of -40ºC to +70ºC.

System Block Diagram
Integrated Data Acquisition
The optional data acquisition circuit provides high-accuracy,
stable 16-bit A/D performance with 100KHz 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 XP, Windows CE, and DOS to simplify application
development.
