 Vortex86 Family Overview

DM&P x86 Semiconductor is proud to provide the Vortex86SX/DX x86 Micro processor, which is based on MPU structure. It is the x86 SoC (System on Chip) with 90nm 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 Vortex86DX is a high performance and fully static 32-bit X86 processor with the compatibility of Windows based, Linux and most popular 32-bit RTOS. It also integrates 32KB write through 4-way L1 cache, 4-way 256KB L2 cache, PCI rev. 2.132-bit bus interface at 33 MHz, DDR2, ROM controller, IPC (Internal Peripheral Controllers with DMA and interrupt timer/counter included), Fast Ethernet, FIFO UART, USB2.0Host and IDE controller within a single 581-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.
