The first-ever CPU with build-in Motion Control function.


Vortex86DX2 is a high performance and fully static 32-bit X86 processor with the compatibility of Windows based, Linux and most popular 32-bit RTOS.

Main Features

  • 32KB write through 4-way L1 cache
  • 256KB write through/write back 4-way L2 cache
  • PCIE bus in at 2.5 GHz
  • DDR2
  • ROM controller
  • ISA
  • I2C
  • SPL
  • IPC (Internal Peripheral Controllers with DMA and interrupt timer/counter included)
  • Fast Ethernet
  • USB2.0 Host and IDE/SATA controller within a single 720-pin BGA package to form a system-on-a-chip (SOC)
