MPC8255AVVPIBB

Overview

The MPC8255AVVPIBB is a PowerQUICC II processor based on the PowerPC G2 core, manufactured by Freescale Semiconductor. It features a 32-bit architecture with an integrated PCI interface and USB controller. The device includes a Communications Processor Module (CPM) for high-speed data handling. It operates at a clock frequency of 200 MHz and utilizes a 480-ball TBGA package measuring 37.5x37.5 mm. The component supports 3.3V I/O and requires a specific core voltage supply.

Feature Summary

• Integrates a PowerPC G2 microprocessor core with 32-bit processing capability
• Includes a dedicated Communications Processor Module for protocol offloading
• Features built-in PCI bus master and target interfaces
• Supports Universal Serial Bus connectivity

Applications

• High-performance networking equipment
• Telecommunications infrastructure systems
• Industrial control applications requiring robust communication protocols

Procurement Notes

Verify the exact suffix to confirm package type and temperature range. Ensure compatibility with existing board designs regarding pinout and power requirements. Confirm RoHS compliance status if required for your region. Check for end-of-life notices as this is an older component. Validate that the supplier provides genuine parts from authorized channels.

Selection Notes

Select this processor when a combination of PCI, USB, and CPM capabilities is required in a single chip. Consider the 200 MHz performance level against system throughput needs. Evaluate the 480-ball TBGA package constraints for PCB layout. Compare against other MPC82xx variants if different peripheral sets are needed.

Part Context

This part belongs to the MPC82xx family of PowerQUICC II processors. These devices were designed for embedded communications applications. The family shares common architectural features but varies in peripheral integration. This specific model emphasizes standard PCI and USB support alongside the CPM.

Replacement Considerations

Check for direct replacements within the MPC82xx series such as the MPC8260 or MPC8265. Verify pin-to-pin compatibility before substitution. Review updated datasheets for any changes in electrical characteristics or supported standards.
