MC143421 Datasheet | Motorola Semiconductor

PCI BUS PERIPHERAL INTERFACE BUS (PIB) MOTOROLA SEMICONDUCTOR TECHNICAL DATA 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 peripherals such as DSP- based analog modems. The Peripheral Interface Bus (PIB) that interfaces this device to the PC peripheral function provides four address lines, byte- wide data, and eight programmable lines that can be used for chip selects, interrupts, and power- down enable. Features - Fully pliant 32- Bit PCI 2.1 Interface - Four Address Lines and Byte- Wide Data - Eight General Purpose I/O Lines - ACPI Power Management and On Now™ Support - Single Digital 100- Pin QFP VLSI Implementation BLOCK DIAGRAM PME# INTERRUPT AUX PIN CONTROL REGISTER AUX[7:0] CNTL SYSTEM CONTROL LOGIC PCI CONFIGURATION REGISTER PIB...
