Intel® IQ80332 I/O Processor

Introduction

1.6Intel® 80332 I/O Processor

About the 80332. The 80332 is a multi-function device that combines the Intel XScale® core with intelligent peripherals, and integrates two PCI Express-to-PCI Bridges. The 80332 consolidates into a single system:

•Intel XScale® core.

•x8 PCI Express Upstream Link.

•Two PCI Express-to-PCI Bridges supporting PCI-X interface on both segments.

•PCI Standard Hot Plug Controller (segment B).

•Address Translation Unit (ATU): PCI-to-Internal Bus Application Bridge, interfaced to the segment A.

•High-Performance Memory Controller.

•Interrupt Controller with 17 external interrupt inputs.

•Two Direct Memory Access (DMA) Controller.

•Peripheral Bus Interface (PBI) Unit.

•Performance Monitor Unit (PMU).

•Application Accelerator Unit (AAU).

•Two I2C Bus Interface Units (BIU).

•Two 16550 Compatible UARTs with flow control (4 pins).

•Eight General Purpose Input Output (GPIO) Ports.

The 80332 is an integrated processor that addresses the needs of intelligent I/O applications and helps reduce intelligent I/O system costs.

PCI Express is an industry standard, high performance, low latency system interconnect. The 80332 PCI Express upstream link is capable of x8 lane widths at 2.5 GHz operation as defined by the PCI Express Specification, Revision 1.0. The addition of the Intel XScale® core brings intelligence to the PCI Express-to-PCI Bridges.

The 80332 integrates dual PCI Express-to-PCI-X Bridges with the ATU as an integrated secondary PCI device. The Upstream PCI Express port implements the PCI-to-PCI Bridge programming model according to the PCI Express Specification, Revision 1.0. The Primary Address Translation Unit is compliant with the PCI-X Specification, Revision 1.0a definitions of an ‘application bridge’.
