MPC8270CVVQLDA

Overview

The MPC8270CVVQLDA is a PowerQUICC II integrated communications processor utilizing the G2_LE core. It features a 32-bit architecture with 16 KB instruction and data caches. The device supports frequencies up to 450 MHz for the CPU and 300 MHz for the CPM. It includes three Fast Communication Controllers (FCCs), four Serial Communications Controllers (SCCs), one Multi-Channel Controller (MCC), and a USB 2.0 controller. Connectivity options include a PCI bridge, Ethernet interfaces, and UTOPIA ports.

Feature Summary

• Dual-issue integer G2_LE core with floating-point unit
• Integrated Communications Processor Module (CPM) for protocol offloading
• PCI bus interface compliant with Specification Revision 2.2
• USB 2.0 full/low rate controller supporting host and slave modes

Applications

• Wired infrastructure communications processing
• Wireless infrastructure communications processing
• High-end communications equipment control and forwarding plane processing
• Networking equipment such as routers and DSLAMs

Procurement Notes

Verify the specific package variant against the ordering suffix. Confirm lead-free status if required by environmental regulations. Check for moisture sensitivity level requirements during storage and handling. Ensure voltage supply specifications match the design constraints for VDD and VDDH.

Selection Notes

Select this component for applications requiring high-performance embedded processing with extensive serial communication capabilities. Consider the separate power supplies for internal logic and I/O when designing the power distribution network. Evaluate thermal management needs based on the estimated power dissipation at the target operating frequency.

Part Context

This part belongs to the MPC8280 PowerQUICC II family, manufactured using 0.13-micron HiP7 process technology. The family includes the MPC8280, MPC8275, and MPC8270 devices. The CVVQ suffix indicates a specific package and temperature range configuration within this product line.

Replacement Considerations

Compatible substitutes within the same family include the MPC8275 and MPC8280, provided the specific feature set such as UTOPIA ports or MCC count meets the application requirements. Verify pin compatibility and software compatibility before substitution.
