MPC8247VRMIBA

Overview

The MPC8247VRMIBA is a member of the PowerQUICC II family, utilizing a 32-bit Power Architecture core with a 603e architecture. It features a modified Communications Processor Module (CPM) and operates at frequencies up to 266 MHz. The device integrates two Fast Communication Controllers (FCCs), three Serial Communication Controllers (SCCs), one QUICC Multi-channel Controller (QMC), and a USB 2.0 interface. It includes a PCI bridge supporting 32-bit data buses up to 66 MHz and an eight-bank memory controller compatible with SRAM, SDRAM, and DRAM. The processor is housed in a 516-pin lead-free PBGA package.

Feature Summary

• Dual-core architecture combining a G2_LE embedded PowerPC core with a RISC-based Communications Processor Module for efficient task distribution.
• Integrated hardware security engine absent; relies on CPM for protocol handling including Ethernet, HDLC, ATM, and TDM interfaces.
• Supports flexible clock configuration via independent PLLs for the core and CPM, enabling optimized power and performance scaling.

Applications

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

Procurement Notes

Verify component authenticity through authorized NXP channels. Confirm RoHS compliance status as indicated in official documentation. Ensure proper ESD handling protocols are followed during installation due to moisture sensitivity classification. Review datasheet specifications regarding operating voltage ranges and thermal management requirements before integration into final designs.

Selection Notes

Select this model when high integration of communication peripherals is required without dedicated hardware encryption engines. Suitable for applications needing robust serial and parallel I/O capabilities managed by the CPM. Consider alternative family members like the MPC8272 if integrated DES/AES security acceleration is necessary for specific compliance standards.

Part Context

This microprocessor belongs to the MPC8272 PowerQUICC II family, which also includes the MPC8272, MPC8248, and MPC8271. These devices share common architectural foundations but differ in peripheral availability and security features. The MPC8247 variant specifically omits the integrated Security Engine found in other family members, focusing instead on general-purpose communications processing.

Replacement Considerations

Direct replacements within the same package and pinout include MPC8247VR and MPC8247ZQ variants. Cross-family upgrades may require significant redesign due to architectural differences between PowerQUICC II and newer generations like QorIQ.
