High reliability and low power applications:
  • Transportation Mobile Systems
  • Industrial Installations
  • Medical Environment
  • Military Environment

The CPU-1421 is ideally suited for applications requiring high reliability and low power consumption such as mobile systems in transportation, industrial, medical and military environments. This module is compliant with the 2002/95/CE (RoHS) directives. This very low power consumption module is ideal for systems that require passive or structural heat dissipation. The CPU-1421 has been designed for harsh environments, resisting vibration, humidity and temperature extremes. The standard operating temperature is 0C to +60C, qualification for -55C to +85C operating temperature range is possible.
This integrated PCI-architecture 5x86 class PC/104-Plus computer is based on the AMD Elan SC520133MHz processor with 64MB of onboard soldered SDRAM for high reliability.
Peripheral interfaces include, four serial ports (2 RS-232, 2 software configurable as RS-232/422/485), two independent 10/100Mbps fast Ethernet controllers, a bi-directional EPP/ECP parallel port, high speed EIDE hard drive interface, speaker port, AT keyboard and PS/2 mouse, real-time clock, watchdog timer, and two additional 16-bit counter/timers free for the user.
The module and the Eurotech embedded BIOS ensures compatibility with popular commercial operating systems such as Windows CE and Linux. The Embedded BIOS is located in a 1MB Flash EPROM and is re-programmable on-board. Set-up parameters are stored in non-volatile Flash memory to enable the module to operate without a battery and avoids corruption of set up data in the field.
A complete ready-to-use hardware development system is available to reduce development times. Accessories include Ethernet adaptors, interface cable kits, power supplies etc.
