NCR ANNOUNCES THE INDUSTRY'S FIRST PCI SCSI PROCESSOR SOLUTION

 NCR ANNOUNCES THE INDUSTRY'S FIRST PCI SCSI PROCESSOR SOLUTION
 COLORADO SPRINGS, Colo., Nov. 13 /PRNewswire/ --NCR Microelectronic Products Division, announced today the availability of the first high- performance single-chip SCSI I/O processor that connects directly to the Peripheral Component Interconnect (PCI) bus, providing a total PCI SCSI solution on the motherboard.
 The NCR53C810 is a third generation, submicron CMOS application- specific standard part (ASSP) which functions as a PCI host master replacing the functionality of an entire SCSI adapter board. It complies with both the PCI standard and the SCSI-2 standard for fast SCSI.
 NCR's SCSI SCRIPTS(TM) processor, utilized by the popular NCR53C7XX family of intelligent SCSI I/O processors, is integrated into the NCR53C810, giving it the same powerful performance, flexibility and ease of programming. The 53C810 permits SCSI bus transfer rates of five megabytes per second asynchronous and ten megabytes per second synchronous. It also permits zero-wait-state, bus mastering and burst data transfer rates in excess of 110 megabytes per second at 33 MHz.
 Michael W. Morrissey, vice president, NCR Microelectronic Products Division, stated, "NCR's introduction of the industry's first PCI- compliant processor is evidence of our strength in SCSI technology and standards, which we have driven for ten years.
 "Our unique PCI solution provides not only the hardware, but also the supporting software which gives our customers everything they need to easily and quickly implement their PCI-based systems. The NCR solution gives our customers a high level of bus interface functionality packed onto a very small die which requires less expensive packaging and less board space, reducing overall system cost," he added.
 Additional features of the 53C810, the first "three volt-friendly" PCI device on the market, include a 64-byte DMA FIFO and an 8-byte synchronous SCSI FIFO which provide speed matching. The PCI chip also minimizes SCSI I/O start latency and performs complex bus sequences without interrupts, including restoration of data pointers, permitting the CPU to perform at maximum speed without interrupts from the SCSI processor.
 The 53C810 is SCSI SCRIPTS programmable and software compatible with the NCR53C720 intelligent SCSI I/O processor for an 8-bit SCSI-2 bus. The unique SCSI SCRIPTS high-level programming language was developed by NCR to ease SCSI-based system software development on the part of customers. The high-performance SCSI core and an intelligent 32-bit DMA bus master are integrated with a SCRIPTS processor to support the PCI system requirements, resulting in both increased protocol and data transfer performance.
 SCSI SCRIPTS also provides for the execution of multi-threaded I/O algorithms and for fast I/O context switching, both of which greatly increase performance. It also allows a target to disconnect and reselect without interrupting the system processor.
 In addition, full functionality of all of NCR's SCSI devices, including the 53C810, is provided by NCR's SCSI Device Management System (SDMS)(TM) software which is based on the ANSI standard Common Access Method (CAM). SDMS includes BIOS and supports all of the major PC operating systems and peripheral types allowing system integrators quick time to market. SDMS version 3.0 is compliant with both CAM 3.0 and ASPI. With SDMS no additional software is needed; however, for customers who want to develop their own software a SCSI compiler and SCRIPTS debugger are also available from NCR.
 The 53C810 also features NCR TolerANT(R) (announced in December 1991) SCSI Active Negation Technology which greatly increases data transmission integrity even in real world cabling environments. TolerANT, which is embedded in the chip drivers and receivers, controls the maximum voltage and current to the SCSI cable, making the drivers compatible with both Alternatives 1 and 2 bus terminator options.
 Prototypes of the PCI chip will be available through distribution in the first quarter of 1993 in a 100-pin plastic flat pack (PFQP). Production quantities will be available in the second quarter of 1993 for $32.40 each in quantities of 1000.
 NCR(R), an AT&T Company develops, manufactures, markets, supports and services enterprise-wide information systems for worldwide markets. NCR Microelectronic Products Division develops, manufactures and markets a wide range of semiconductor and board-level products including highly integrated digital and mixed-signal cell-based ASICs, SCSI, graphics, Ethernet LAN products, disk array (RAID) subsystems and multichip modules. The company is the world's leading supplier of SCSI products and mixed-signal cell-based ASICs and offers a dedicated customer-owned tooling (COT) service.
