MPC8255AZUPIBB

Overview

The MPC8255AZUPIBB is a PowerQUICC II integrated communications processor based on the EC603e core. It features a dual-issue integer architecture with separate 16-Kbyte instruction and data caches, supporting frequencies up to 300 MHz. The device includes a Communications Processor Module (CPM) with two Fast Communications Controllers (FCCs), one Multichannel Controller (MCC), four Serial Communications Controllers (SCCs), two Serial Management Controllers (SMCs), SPI, and I2C interfaces. It utilizes a 480-ball TBGA package.

Feature Summary

• Dual-issue G2 core with floating-point unit and MMU
• Integrated CPM for protocol processing
• Multiple serial communication controllers
• Separate power supplies for logic and I/O

Applications

• Telecommunications equipment
• Network infrastructure devices
• Industrial control systems

Procurement Notes

Verify the specific suffix 'ZUPIBB' against official NXP documentation to confirm pinout and voltage compatibility. Ensure the component meets RoHS requirements if applicable to your design constraints. Confirm availability status as older generation parts may have limited supply chains.

Selection Notes

Select this processor for applications requiring high-performance protocol handling alongside general-purpose computing. Evaluate thermal management needs due to power dissipation at higher clock speeds. Consider the footprint compatibility with other MPC82xx family members if system scalability is required.

Part Context

This part belongs to the MPC826xA family of HiP4 processors. It shares architectural similarities with the MPC8260 but offers a reduced peripheral set optimized for cost-sensitive designs while maintaining software compatibility with the broader PowerQUICC II ecosystem.

Replacement Considerations

Check for MPC8255ACZUMHBB or MPC8255AVRPIBX as potential functional equivalents within the same family. Verify pin-to-pin compatibility and electrical characteristics before substitution.
