DM&P Semiconductor Inc. is proud to provide the MPU based Vortex86SX x86 microprocessor. The Vortex86SX is an x86 compatible System-on-Chip (SoC) manufactured with a 0.13 micron process and designed to consume less than 1 watt of electricity. It integrates various features such as mulitple I/O ports (RS232, Parallel, USB, GPIO), a Watch Dog timer, MTBF counter, Lan-on-Chip (LoC), and JTAG into a single BGA chip.

Inside its 456-pin BGA package, the Vortex86SX packs 32kb write through direct map L1 cache, PCI rev. 2.1 32-bit bus interface at 33 MHz, SDRAM, DDR2, ROM controller, IPC (Internal Peripheral Controllers with DMA and interrupt timer/counter included), Fast Ethernet MAC, FIFO UART, and USB 2.0 Host and IDE controllers to provide an ideal solution for the embedded systems and communications products such as thin clients, NAT routers, home gateways, access points and tablet PCs.

Special Features

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

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.


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.
