Introduction

DM&P Semiconductor Inc. is proud to provide the MPU based Vortex86DX2 x86 microprocessor. The Vortex86DX2 is an x86 compatible System-on-Chip (SoC) manufactured with a 90nm process and designed for ultra low power consumption. It integrates various features such as multiple I/O ports (RS-232, Parallel, USB and GPIO), BIOS, Watch Dog Timer, Power Management, MTBF counter, LoC (LAN on Chip), JTAG, GPU, and Motion Control into a single BGA chip.

Inside its 720-pin BGA package, the Vortex86DX2 packs 32kb write through 4-way L1 cache, 4-way 256KB L2 cache, 2.5GHz PCI-E Bus, DDR2, ROM controller, ISA, I2C, SPI, IPC (Internal Peripheral Controllers with DMA and interrupt timer/counter included), Fast Ethernet, FIFO UART, and USB 2.0 Host and IDE/SATA 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.
