The 1GHz dual Core CPU with selectable I/O.


Vortex86DX3 is a 32-bit x86-architecture dual-core microprocessor with the compatibility of Windows based, Linux and most popular 32-bit RTOS.

Main Features

  • 32KB write through 8-way L1 cache
  • 512KB writethrough/write back 4-way L2 cache
  • PCIE bus at 2.5 GHz
  • DDR3
  • ROM controller
  • ISA
  • I2C
  • SPI
  • IPC (Internal Peripheral Controllers with DMA and interrupt timer/counter included)
  • Fast Ethernet
  • USB2.0 Host
  • IDE/SATA controller within a single 720-pin BGA package to form a system-on-a-chip (SOC)
It provides an ideal solution for the embedded system and communications products (such as thin client, NAT router, home gateway, access point and tablet PC) to bring about desired performance.
