The CPU design for industrial application.


DM&P Semiconductor Inc. is proud to provide the MPU based Vortex86DX x86 microprocessor.

Vortex86DX is an x86 compatible System-on-Chip (SoC) manufactured with a 90nm process and designed to consume less than 1 watt of electricity.

Main Features

  • multiple I/O ports (RS-232, Parallel, USB and GPIO)
  • BIOS
  • Watch Dog Timer
  • Power Management
  • MTBF counter
  • LoC (LAN on Chip)
  • JTAG into a BAG chip

Inside its 581-pin BGA package

  • 32kb write through 4-way L1 cache
  • 4-way 256KB L2 cache
  • PCI rev. 2.1 32-bit bus interface at 33 MHz
  • DDR2
  • ROM controller
  • IPC (Internal Peripheral Controllers with DMA and interrupt timer/counter included)
  • Fast Ethernet MAC
  • USB 2.0 Host and IDE controllers to provide an ideal solution for the embedded systems and communications products

Special Features of Vortex86DX

Integrated MTBF Counter

  • One-time write Flash area for number of MTBF hour before shipment. Timer count up by “hour”. Built-in TTL alert signal will be enabled after time counter over MTBF number. Fault tolerance – Redundancy

Fault tolerance – Redundancy

  • Two CPU boards may be run in parallel—connected to the same ISA bus and executing the same software. Each board will be designated Master or Slave during power on. The system detects six different fail conditions and responds accordingly. I/O can also be switched between boards during each fail over. Contains a built int System Fail Counter.

ISO in Chip

  • 32 Byte one-time write Flash area containing all service tracking data. Data includes: Date codes of all major components, Model and Serial numbers, Unique serial code of SoC, Distributor code, Ship date, etc.
