MPC8250ACZQIHBC

Overview

The MPC8250ACZQIHBC is a PowerQUICC II communications processor based on the PowerPC G2 core. It features a dual-issue integer core with separate 16-Kbyte data and instruction caches, supporting frequencies up to 200 MHz. The device integrates a high-performance Communication Processor Module (CPM) for protocol handling, a 60x-to-PCI bridge, and a twelve-bank memory controller. It operates with separate 1.8 V internal logic and 3.3 V I/O supplies, utilizing distinct PLLs for the core and CPM to optimize power and performance.

Feature Summary

• Dual-issue PowerPC G2 core with floating-point unit and MMU
• Integrated Communication Processor Module (CPM) with DMA
• 60x-to-PCI bridge supporting host or agent modes
• Separate power domains for core logic and I/O

Applications

• Network routers and switches
• Base station controllers
• Industrial communication gateways
• Voice over Internet Protocol (VoIP) systems

Procurement Notes

Verify the specific suffix ZQI against official NXP documentation to confirm package type and temperature range. Confirm component status as this series may be subject to end-of-life notices. Ensure compatibility with existing board designs regarding pinout and voltage requirements before procurement.

Selection Notes

Select this processor for applications requiring high-speed communications processing with integrated PCI connectivity. Consider the footprint compatibility with the MPC8260 if migrating from previous designs. Evaluate thermal management needs due to power dissipation characteristics at higher clock speeds.

Part Context

This component belongs to the Freescale/NXP PowerQUICC II family, designed for embedded communications systems. It succeeds earlier generations by offering enhanced bus interfaces and integrated security features. The MPC8250 provides a scalable platform for networking equipment requiring robust protocol processing capabilities.

Replacement Considerations

The MPC8250ACZUMHBC is a documented alternative within the same family. Verify pin compatibility and electrical specifications before substitution.
