• Increased reliability

Athena III combines a full-featured wide temperature SBC with a professional quality data acquisition circuit, all on a compact board with PC/104 I/O expansion. This 2-in-1 design reduces the size and weight of your embedded system, while also helping to simplify manufacturing logistics such as purchasing, warehousing, and assembly. As a third generation product, Athena III demonstrates Diamond's support for long-lifecycle applications. It offers the latest processor and I/O technologies for new applications, while remaining backwards compatible with prior models to extend existing product lifetimes.

Athena III offers some of the highest feature density available in a compact SBC with rugged, wide-temperature, shock and vibration qualified operation. Its combination of size, weight, performance, and power consumption is an ideal fit for applications that require solid performance and a comprehensive range of I/O, without the burden of high cost or power consumption.

The Athena III SBC provides an ideal solution for applications requiring ruggedness.

Its many rugged features include:

• Soldered memory for increased immunity to shock and vibration
• -40ºC to +85ºC operating temperature fully tested
• MIL-STD-202-G shock and vibration qualification (test report available)
• Thicker PCB (.093" / 2.4mm) increases rigidity and enhances long-term reliability in high vibration environments
• 2-in-1 SBC + data acquisition reduces size and weight and eliminates bus connectors and spacers for a more rugged solution

Athena III includes a complete set of standard I/O features:

• 4 serial ports with RS-232/422/485 protocol support, configurable via BIOS (2 ports have 128-byte FIFOs and 460.8Kbps max data rate)
• 4 USB 2.0 ports
• Additional USB port for bolt-on solid state flash up to 8GB
• SATA port for external mass storage
• Parallel port for legacy applications
• PS/2 keyboard / mouse ports
• 1 Gigabit Ethernet port with 10/100/1000Mbps compatibility
• VGA and LVDS LCD output with dual independent display capability
• 24 digital I/O lines

System Block Diagram

Integrated Data Acquisition

Athena III includes a complete analog and digital data acquisition circuit integrated onto the board. The analog input circuit includes 16 single-ended / 8 differential channels with 16-bit resolution and programmable gain. The extremely high input impedance ensures accurate measurements, while the fault-protected input multiplexors provide protection from overvoltage conditions as well as live inputs during a power-off state. A 2048-sample FIFO with programmable threshold supports smooth interrupt-based sampling at any sample rate up to 200KHz.

The circuit also features 4 12-bit analog voltage outputs with programmable output ranges, 24 digital I/O lines with programmable direction, and 2 counter/timers which can be used for A/D timing, timer-driven interrupts, or general counting functions.

All data acquisition features are supported by our free, best-in-class Universal Driver programming software which simplifies application development.
