The AMD Elan SC520 processor runs at 133 MHz with 64 MB of onboard soldered SDRAM standard. A 1 MB onboard programmable flash holds the BIOS plus setup parameters, eliminating the need for battery backed SRAM, according to Eurotech. The BIOS includes support for “virtual peripherals,” which enable peripheral devices such as the keyboard, display, and boot device to be redirected to a remote host computer.

Eurotech lists the following key features and specifications for the CPU-1421:

  • Processor — AMD Elan SC520 at 133 MHz
  • Memory — 64 MB onboard soldered SDRAM standard, 128 MB available
  • Display — none
  • Storage — EIDE and floppy interfaces
  • I/O ports:
    • 2 10/100 Ethernet, RJ45 connectors available as accessory
    • 4 serial — 2 RS232, 2 RS232/422/485
    • Parallel port
    • PS/2 keyboard and mouse
    • 2 16-bit counter/timers
  • Expansion — ISA and PCI busses per PC/104-Plus standard
  • Operating temperature:
    • Standard — 0 to 60 degrees C
    • Extended range — -55 to +85 degrees C
  • Power — +5V only, 4.6W

Eurotech says it offers a complete ready-to-use hardware development system that includes the CPU-1421, a VGA module, power supply, cables, and connectors. In addition to Linux, the CPU-1421 also supports Windows CE, QNX, and VxWorks.
