MPC8250ACVVMHBC

Overview

The MPC8250ACVVMHBC is a PowerQUICC II communications processor based on the G2 core. It features a dual-issue integer core supporting frequencies up to 200 MHz, with separate 16-Kbyte data and instruction caches. The device includes a Communication Processor Module (CPM) with an embedded 32-bit RISC microcontroller, three Fast Communications Controllers (FCCs), four Serial Communications Controllers (SCCs), two Serial Management Controllers (SMCs), and one SPI controller. It supports PCI bus operation at 66 MHz and provides a 64-bit 60x bus interface.

Feature Summary

• Integrated Communication Processor Module (CPM) for flexible protocol support
• Dual-issue EC603e-compatible G2 core with floating-point unit
• PCI host bridge with DMA capabilities and hot-swap support
• Separate power supplies for internal logic and I/O

Applications

• Enterprise networking equipment
• Telecom transmission and switching systems
• Industrial control applications

Procurement Notes

Verify the specific suffix ACVVMHBC against the manufacturer's official ordering guide to confirm package type, temperature range, and revision level. Ensure compatibility with existing PCB footprints and voltage requirements before procurement. Check for end-of-life status or alternative sourcing options as this component may be discontinued.

Selection Notes

Select this processor for applications requiring high-performance communications processing with integrated Ethernet and serial interfaces. Consider the 200 MHz core speed and CPM flexibility for complex protocol handling. Evaluate thermal management needs due to power dissipation characteristics and ensure system design supports the required 1.8 V core and 3.3 V I/O voltages.

Part Context

This component belongs to the Freescale/NXP MPC82xx series of PowerQUICC II processors. It is footprint-compatible with the MPC8260. The MPC8250 is designed for communications applications, integrating a powerful CPU core with a dedicated communication processor module to offload protocol processing tasks from the main CPU.

Replacement Considerations

The MPC8250ACVVMHBC is footprint-compatible with the MPC8260. Verify electrical and functional differences when substituting.
