MOTOROLA Order this document by MC143421/D SEMICONDUCTOR TECHNICAL DATA MC143421 Advance Information PCI Bus Interface The MC143421 PCI Bus Interface chip is a low cost and highly integrated PCI interface solution that includes Advanced Configuration Power Interface (ACPI) features. It is designed to enable the addition of a PCI interface to PC FU SUFFIX peripherals such as DSP–based analog modems. QFP The Peripheral Interface Bus (PIB) that interfaces this device to the PC CASE 842D peripheral function provides four address lines, byte–wide data, and eight programmable lines that can be used for chip selects, interrupts, and ORDERING INFORMATION power–down enable. MC143421FU QFP Features • Fully Compliant 32–Bit PCI 2.1 Interface • Four Address Lines and Byte–Wide Da
