ATHM800-256N

Diamond Systems ATHM800-256N Athena II PC/104 Single Board Computer

The Diamond Systems ATHM800-256N is a rugged Athena II embedded single-board computer featuring an 800MHz VIA Mark processor, 256MB of onboard DRAM and PC/104 ISA expansion. This exact configuration is the non-data-acquisition version of the 800MHz Athena II and uses the standard high-profile heatsink.

The ATHM800-256N integrates processor, memory, VGA and LVDS graphics, 10/100 Ethernet, USB, serial communications, IDE storage and PC/104 expansion in a compact industrial embedded computing platform.

800MHz VIA Mark Processor

The ATHM800-256N is specifically configured with an 800MHz VIA Mark integrated processor. The VIA Mark platform provides Pentium III-class embedded computing functionality with integrated system-controller features for compact industrial applications.

256MB System Memory

The board provides 256MB of onboard DRAM operating on a 100MHz memory bus. The integrated memory configuration eliminates the need for a removable memory module.

Non-Data-Acquisition Configuration

The ATHM800-256N does not include onboard data acquisition. This is the primary distinction between the ATHM800-256N and ATHM800-256A.

Applications requiring integrated analog inputs, analog outputs, digital I/O and counter/timer data-acquisition functions should use the ATHM800-256A rather than the ATHM800-256N.

VGA and LVDS Display Support

Integrated graphics provide VGA CRT and 24-bit dual-channel LVDS flat-panel display support. The graphics subsystem includes 2D/3D acceleration and MPEG-2 hardware acceleration with display resolutions up to 1600 x 1200.

10/100 Ethernet

Integrated 10/100Base-T full-duplex Ethernet provides network connectivity for industrial control and embedded computing applications.

USB and Serial Connectivity

The Athena II platform provides four USB 1.1 interfaces and four serial ports for peripheral and industrial communications.

Two serial ports use 16550-compatible UARTs. Two additional ports use 16850-compatible UARTs and support RS-232, RS-422 and automatic half-duplex RS-485 operation.

IDE and Flash Storage

The ATHM800-256N provides IDE storage connectivity supporting compatible hard drives and solid-state FlashDisk devices.

PC/104 Expansion

The board provides a PC/104 ISA expansion interface for compatible industrial I/O, communications and control modules.

Athena II uses Diamond Systems' custom small-form-factor PCB while retaining the PC/104 mounting method and interface specification.

High-Profile Heatsink

The ATHM800-256N is the standard 800MHz non-data-acquisition configuration with a high-profile heatsink and an operating temperature specification of -40°C to +85°C.

For applications requiring reduced vertical clearance, Diamond Systems produced the ATHM800-256NLP with a low-profile heatsink.

ATHM800 Model Identification

  • ATHM800-256A: 800MHz, 256MB DRAM, onboard data acquisition, high-profile heatsink
  • ATHM800-256N: 800MHz, 256MB DRAM, no data acquisition, high-profile heatsink
  • ATHM800-256ALP: 800MHz, 256MB DRAM, onboard data acquisition, low-profile heatsink
  • ATHM800-256NLP: 800MHz, 256MB DRAM, no data acquisition, low-profile heatsink

Industrial Applications

The Diamond Systems ATHM800-256N is suitable for industrial automation, machine control, robotics, transportation systems, embedded controllers, manufacturing equipment and other rugged applications requiring an 800MHz PC/104 single-board computer without integrated data acquisition.
