 Vortex86 Family Overview

DM&P x86 Semiconductor is proud to provide the Vortex86SX x86 Microprocessor, which is based on MPU structure. It is the x86 SoC (System on Chip) with 0.13 micron process and ultra low power consumption design (less than 1 watt). This comprehensive SoC has been integrated many features, such as various I/O (RS-232, Parallel, USB and GPIO), BIOS, WatchDog Timer, Power Management, MTBF counter, LoC (LAN on Chip),JTAG etc., into a BGA packing single chip.

The Vortex86SX is a high performance, which is compatible with DOS and Linux. It integrates 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, USB2.0 Host and IDE controller into a System-on-Chip (SoC) design.

Furthermore, this outstanding Vortex86SX SoC can not only meet the requirements of embedded applications, such as Electronics Billboard, Firewall Router, Industrial Single-Board-Computers, Receipt Printer Controller, Thin Client PC, Auto Vehicle Locator, Finger Print Identification, Web Camera Thin Server, RS232-to-TCP Transmitter. but also can meet the critical temperature demand, spanning from -40 to +85 degree C.

The Vortex86SX is a high performance and fully static 32-bit X86processor with the compatibility of Windows based, Linux and most popular32-bit RTOS. It also integrates 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, USB2.0 Host and IDE controller within a single 456-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.
