Product Description
The Intel 430HX PCIset helps you achieve best-of-class price/performance for business PCs. With Intel Concurrent PCI architecture you can design a new generation of Pentium(r) processor-based business PCs with built-in scalability - enabling you to add features and capabilities and maintain high levels of system performance. Universal Serial Bus (USB) support enables a wide spectrum of new peripheral options and hot Plug and Play "right out of the box."

With uncompromised EDO timings the 430HX matches the performance advantage of an asynchronous L2 cache-based system, without the cache. It supports 64Mbit DRAM and 8 RAS lines (for up to 512MB of system memory). Memory address buffers are built into the system controller. Integrated deep-posting and FIFO buffers enable concurrent activity on both sides of the system controller and data paths for improved CPU utilization. ECC and parity memory support are integrated into the chip set. The 430HX PCIset single-chip host bridge requires 60% less board real estate.

The Intel 430HX PCIset builds on the core architecture of the award-winning Intel 430FX PCIset. Because it offers full compatibility with BIOS, drivers and development tools, the 430HX makes it easy to build on your existing investment to support the next generation of more powerful business PCs.
