MPC8260ACZUMHBB

Overview

The MPC8260ACZUMHBB is a PowerQUICC II integrated communications processor featuring an EC603e core operating at frequencies up to 300 MHz. It utilizes a 480-pin TBGA package and supports separate power supplies for internal logic (1.7–2.5 V) and I/O (3.3 V). The device includes a 32-bit Communications Processor Module (CPM), dual 16-Kbyte caches, and a 64-bit 60x bus interface.

Feature Summary

• Dual-issue integer core with floating-point unit and hardware MMU
• Integrated Communications Processor Module (CPM) for protocol offloading
• Separate PLLs allowing independent core and CPM frequency optimization
• Sixty-to-PCI bridge supporting host and agent modes

Applications

• Networking equipment requiring encryption capabilities
• Small and medium enterprise routers
• Virtual private network and firewall routers
• Wireless access points and residential gateways
• xDSL equipment

Procurement Notes

Verify the specific suffix ZUMHBB against official NXP documentation to confirm package type and temperature range. Ensure compatibility with existing board designs regarding voltage levels and pin configurations before procurement.

Selection Notes

Select this component for applications requiring high-performance communication processing with hardware security features. Consider the dual-core architecture for balancing low-level peripheral tasks with high-level processing needs.
