The CoreModule/XTPlus offers a high performance PC compatible subsystem in a compact, preconfigured module. Within just 14 square inches of space, the CoreModule/XTPlus includes the equivalent functions of a PC motherboard plus several additional expansion cards.

Specifications

PC Motherboard Functions

  • 16-bit NEC V51 CPU, 16 MHz (V30 core, 8086 superset)
    • System DRAM:
      • 2M bytes onboard DRAM
      • LIM 4.0 compatible EMS memory management
  • 3 DMA channels (8237 equivalent)
  • 8 interrupt channels (8259 equivalent)
  • 3 programmable counter/timers (8254 equivalent)
  • PC-compatible keyboard port
  • Speaker port with 0.1 watt drive
  • 8-bit PC/104 expansion bus
  • Award ROM-BIOS with Ampro extensions

Additional Onboard Functions

  • Real time clock; requires external 3.0-3.6V battery (Tadiran TL-5242/W or equivalent)
  • Serial/parallel controller:
    • Two PC-compatible COM ports with full handshaking (82C50 equivalent)
    • On-board generation of +/-9V for RS232C signal levels
    • Parallel printer port with bidirectional data lines
  • Two 32-pin byte-wide memory sockets:
    • One DIP socket, usable with 32K-1M byte EPROMs, 32K-512K Flash EPROMs, or 32K-512K SRAMs
    • One PLCC socket, usable with 128K-1M byte EPROMs or 32K-512K Flash EPROMs
    • RTC backup battery converts SRAM in DIP socket to NOVRAM
    • Software-controlled +12V programming power for Flash EPROM
    • Software-controlled write protect
    • Configurable as 32K-, 64K-, or 128K-byte window, addressed in the range D0000-EFFFFh
  • 1K-bit configuration EEPROM, with 512 bits for OEM use
  • Watchdog timer:
    • Utilizes real time clock alarm function
    • Timeout triggers hardware reset or non-maskable interrupt

BIOS Enhancements

  • Solid State Disk (SSD) support:
    • Substitutes EPROM, Flash EPROM or NOVRAM devices for normal floppy drives
    • SSDs may coexist with standard floppy and/or hard disk drives
  • SCSI services:
    • Supports DOS-based system operation using a wide variety of SCSI drives
    • Adds a unique SCSI/BIOS function to simplify development of custom SCSI applications
    • SCSI and IDE hard disks may coexist
  • Extended floppy services: supports all PC and PC/AT capacities, including 360K, 720K, 1.2M, and 1.44M byte formats
  • Watchdog timer support: initializes onboardwatchdog timer: adds BIOS function for use by application software
  • Serial console option: substitutes an ASCII terminal or other serially-connected device for the standard PC keyboard and display
  • Serial loader: allows download of executable code from a remote device prior to system boot
  • EEPROM access function: provides high level access to the 512-bit nonvolatile OEM data area in the configuration EEPROM
  • OEM "hooks:" execute custom code prior to system boot; allows system customization without BIOS modification
