MPC8247CZQMIBA

Overview

The MPC8247CZQMIBA is a microprocessor from the NXP PowerQUICC II family, utilizing a 32-bit PowerPC G2_LE core. It operates at frequencies up to 266 MHz and features a modified Communications Processor Module (CPM). The device integrates two Fast Communication Controllers (FCCs), three Serial Communication Controllers (SCCs), and one Universal Serial Bus (USB) 2.0 controller. It includes a PCI bridge supporting 32-bit data buses up to 66 MHz. The processor is housed in a 516-pin PBGA package with lead spheres.

Feature Summary

• Dual-core architecture combining a PowerPC G2_LE core with a RISC-based Communications Processor Module for efficient task distribution.
• Integrated hardware support for dual Fast Ethernet MACs and USB 2.0 full/low rate interfaces.
• Includes a 60x-to-PCI bridge enabling high-speed connectivity and DMA memory block transfers.
• Features an eight-bank memory controller compatible with SRAM, SDRAM, DRAM, and Flash.

Applications

• Small and medium enterprise routers
• Virtual private network (VPN) equipment
• Wireless access points
• Residential gateways

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific ordering suffix matches the required lead-free or leaded specifications. Ensure compliance with RoHS directives if applicable to your assembly process. Check for moisture sensitivity levels and storage conditions prior to soldering. Validate that the part number corresponds exactly to the intended application requirements.

Selection Notes

Select this processor for applications requiring integrated communications processing without dedicated security engines. Consider the 516-pin PBGA package constraints and thermal management needs. Evaluate the frequency scaling options between the core and CPM for power optimization. Ensure compatibility with existing memory controllers and peripheral interfaces such as PCI and Ethernet.

Part Context

This component belongs to the MPC8272 PowerQUICC II family, which also includes the MPC8272, MPC8248, and MPC8271. These devices share a common architectural foundation but differ in feature sets like security engines and ATM support. The MPC8247 variant specifically omits the integrated security engine found in higher-end models.

Replacement Considerations

Direct replacements within the same family include the MPC8247VRMIBA, which differs only in package type (lead-free vs. lead spheres). Other family members like the MPC8271 offer similar communication capabilities but may lack specific interface configurations.
