XPC860PZP80D4

Overview

The XPC860PZP80D4 is a component within the Motorola MPC860 PowerQUICC family, designed for communications and networking controller applications. It integrates a PowerPC processor with peripheral solutions to deliver higher performance in device operation flexibility and capability extensions. The architecture supports static design operations up to 40 MHz, utilizing a complete memory controller with eight banks and a Communications Processor Module (CPM). Key integrated peripherals include four Serial Communication Controllers (SCCs), two Serial Management Channels (SMCs), one SPI interface, and one I2C port. The device operates at 3.3 V with 5V TTL compatibility and features low power support capabilities alongside a debug interface.

Feature Summary

• Integrates a PowerPC processor core with a Communications Processor Module (CPM) for unified processing and communication control.
• Includes dedicated hardware resources such as four SCCs, two SMCs, and an Ethernet MAC for network connectivity.
• Supports dynamic bus sizing for 8, 16, and 32-bit data buses to optimize memory interface efficiency.
• Features integrated instruction and data MMUs along with dual-port RAM for enhanced system management.

Applications

• Communications controller systems
• Networking equipment controllers
• Integrated router or switch platforms

Procurement Notes

Verify that the specific suffix D4 corresponds to the intended mask set and revision level, as the MPC860 family includes multiple variants like MPC860P and MPC860T with differing cache sizes. Confirm the package type matches the required PCB footprint, typically BGA. Since this product line is no longer recommended for new designs, ensure long-term supply availability meets project lifecycle requirements before finalizing procurement plans.

Selection Notes

Select this component when a static design operating at 40 MHz is sufficient for the application's throughput needs. Consider the integrated CPM if complex serial protocols like HDLC or ATM are required without external controllers. Evaluate the trade-off between the standard 4Kb instruction cache of the base model versus the 16Kb cache available in the MPC860P variant if code execution speed is critical.

Part Context

The XPC860PZP80D4 belongs to the broader MPC860 PowerQUICC family, which was developed to provide an integrated processor and peripheral solution for high-performance embedded communications. This family succeeded earlier architectures by offering lower power consumption and stronger third-party tool support through the Our Design Alliance Program. The part represents a specific configuration within this lineage, focusing on serial and parallel communication integration.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The source indicates the MPC860 series is no longer manufactured. Designers should consult NXP official documentation for current alternative microcontroller families suitable for modern networking applications.
