(408) 496-0900 INTEL ANNOUNCES 82430 PCIset FOR PENTIUM(TM) PROCESSOR FOLSOM, Calif., March 22, 1993 -- Intel Corporation today announced the industry's first Peripheral Component Interconnect (PCI) chip set designed exclusively for use with the Pentium(TM) Processor. The 82430 PCIset enables OEMs to develop fifth generation desktop PCs that exploit the full performance of the Pentium(TM) Processor and the high I/O bandwidth of the PCI architecture. The 82430 PCIset includes flexible design options that allow OEMs to develop high performance PCs targeted at multiple price/performance points. To provide greater design efficiency and faster time to market, the 82430 PCIset also comes with a rich set of design tools, specifications and test data. "The 82430 PCIset was created from the ground up to address the specific system design requirements of the Pentium(TM) CPU," said Ron Smith, general manager of Intel's Integrated Microcomputer Division. "This is the next step in incorporating PCI throughout our entire product road map and further establish PCI as the industry standard local bus architecture." 82430 PCIset Performance The 82430 PCIset overcomes data bottlenecks imposed by graphics-intensive operating systems and applications by allowing the graphics subsystems to take full advantage of the Pentium(TM) Processor speed. Graphics performance in excess of 50M Winmarks becomes possible with the 82430 PCIset. 82430 PCIset/IU-040 The core of the 82430 PCIset architecture is the 82434LX, an integrated PCI, cache and main memory controller that connects directly to the Pentium(TM) Processor. In addition to the control functions, the device integrates Tag SRAMs, providing a cost and board space saving by eliminating the need for external SRAMs to store the address tags. The cache controller, which supports both a write through and write back protocol, enables the Pentium(TM) Processor to access the cache with zero waitstate burst cycles. The cache controller further enhances CPU performance by supporting up to 512K byte of cache with either standard or burst mode SRAM. Two Local Bus Accelerator components in the 82430 PCIset -- called the 82433LX -- manage the protocol changes between the host bus and PCI, ensuring full use of the 64-bit Pentium(TM) Processor data path. The PCI local bus allows multiple bus masters to transfer data concurrently with Pentium(TM) CPU transfers. System Flexibility The 82430 PCIset supports multiple combinations of on-board and connector-based PCI peripheral devices. It also includes an ISA or EISA expansion bus that connects to PCI. The ISA and EISA expansion bus solutions allow OEMs to develop systems that support additional standard I/O expansion cards. The ISA interface is incorporated into a single chip, the 82378IB, that connects directly to PCI. The EISA interface consists of two components: the PCI to EISA Bridge, the 82375EB, and the EISA System Component, the 82374EB. The ISA implementation of the 82430 PCIset supports up to six expansion slots while the EISA version supports up to eight slots. To provide OEMs with maximum design flexibility to target multiple price/performance points, the 82430 PCIset supports the following design options: 0, 256K and 512K byte cache memory; DRAM from 2 MB to 192 MB; write-through or write-back cache controller; standard (asynchronous) and burst (synchronous) SRAM; and memory speeds of 50ns, 60ns and 70ns. The 82430 PCIset supports both the 60-MHz and 66-MHz versions of the Pentium(TM) CPU. Design Tools Because the Pentium(TM) Processor introduces a new set of design challenges, the 82430 PCIset comes with multiple tools and specifications that will increase design efficiency and shorten time-to-market. 82430 PCIset/IU-040 The foundation for an OEMs design work is found in The Pentium Processor/82430 PCIset Open Design Guide, which includes architectural and functional descriptions, performance trade-offs, board schematics and layout, development tools and BIOS information, and I/O buffer model data. To ensure robust and reliable Pentium Processor designs, the 82430 PCIset reference design includes over 5,000 hours of Spice simulations. The design guide also includes "EZ-Route Layout" information, maximizing design and layout flexibility without requiring any modeling by the OEM. About PCI PCI is a local bus architecture that enables a glueless interface so OEMs can now design systems with high performance peripherals, such as LAN, SCSI, graphics and video, on a fast local bus. The PCI Special Interest Group, with industry wide support from more than 80 companies, was formed to establish PCI as industry standard and manage the specification. Intel i ntroduced the industry's first PCI ship set -- the 82420 PCIset for the Intel486(TM) microprocessor -- on November 16, 1992. Pricing and Availability Samples of the 82430 PCIset are available now with production quantities available in Q2 '93. In 10,000 unit quantities, the ISA 82430 PCIset costs $76.00 (U.S.) and the EISA 82430 PCIset costs $98.00.
