MPC860DPZQ80D4

Overview

The MPC860DPZQ80D4 is a microprocessor from the PowerQUICC family, featuring a single 32-bit Power Architecture core operating at up to 80 MHz. It includes a 16 Kbyte instruction cache and an 8 Kbyte data cache. The device supports Ethernet (10/100 Mbps) and ATM interfaces, along with a Communications Processor Module (CPM). It utilizes a 357-pin PBGA package and operates on a 3.3 V supply voltage.

Feature Summary

• Integrated Power Architecture core with MMUs and set-associative caches
• Support for Ethernet and ATM protocols via dedicated controllers
• Communications Processor Module (CPM) with dual-port RAM
• Multiple serial communication controllers and management channels

Applications

• Network controller applications
• Communication systems
• ATM network equipment
• Ethernet-based embedded systems

Procurement Notes

Verify component authenticity through authorized NXP distributors or certified secondary market suppliers. Confirm datasheet revision matches Rev. 10 specifications. Check for lead-free compliance status as indicated in official documentation. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this model for designs requiring integrated ATM and Ethernet capabilities within a single chip. Consider the 16 Kbyte instruction cache variant over smaller cache options if code execution performance is critical. Verify that the 357-pin BGA footprint aligns with PCB layout constraints and thermal management strategies.

Part Context
