MPC8250AVRIHBC

Overview

The MPC8250AVRIHBC is a PowerQUICC II communications processor featuring a dual-issue EC603e core operating at frequencies up to 200 MHz. It integrates a 32-bit RISC Communications Processor Module (CPM) with 32 Kbytes of dual-port RAM, three Fast Communications Controllers (FCCs), four Serial Communications Controllers (SCCs), and two Serial Management Controllers (SMCs). The device includes a 60x-to-PCI bridge supporting 66 MHz operation, a twelve-bank memory controller for SDRAM/DRAM/SRAM, and separate 1.8 V logic and 3.3 V I/O power supplies.

Feature Summary

• Dual-issue integer core with separate instruction and data caches
• Integrated Communications Processor Module offloading peripheral tasks
• Support for multiple protocols including Ethernet, HDLC, and TDM
• Programmable PCI host bridge with DMA capabilities

Applications

• Wired and wireless infrastructure communications processing
• High-end routers and DSLAMs
• Telecom switching equipment and cellular base stations
• Remote access concentrators

Procurement Notes

Verify the specific suffix AVRIHBC against official NXP documentation to confirm package type and temperature range. Confirm current availability status as older MPC82xx series parts may be discontinued or subject to last-time buys. Ensure compatibility with existing board designs regarding pinout and voltage requirements before procurement.

Selection Notes

Select this component for applications requiring high-performance layer 2 forwarding combined with control plane processing. The integrated CPM reduces CPU load by handling serial protocols independently. Consider thermal management requirements for sustained operation at higher clock speeds and verify memory interface compatibility with target DRAM or SRAM types.

Part Context

This part belongs to the PowerQUICC II family, designed for embedded communications systems. It utilizes HiPerMOS7 process technology to deliver performance improvements over previous generations while maintaining software compatibility. The MPC8250 serves as an integrated host processor combining a PowerPC core with extensive peripheral support for networking applications.

Replacement Considerations

The MPC8250ACVRIHBC is footprint-compatible with the MPC8260. Verify electrical characteristics and pin assignments when substituting within the MPC82xx family. Consult official replacement guides for end-of-life notifications and recommended alternative part numbers from NXP Semiconductors.
