MPC8347CZQAGDB

Overview

The MPC8347CZQAGDB is a PowerQUICC II Pro integrated host processor based on the e300 core, operating at up to 667 MHz. It features a DDR SDRAM controller supporting 32- or 64-bit interfaces with ECC, dual three-speed Ethernet controllers (TSECs), and a PCI interface compliant with Revision 2.2. The device includes a security engine for IPSec and SSL/TLS processing, dual USB 2.0 controllers, and a local bus controller. It utilizes a 130 nm CMOS process with a 672-pin TBGA package.

Feature Summary

• Integrated high-performance superscalar e300 processor core with floating-point support
• Dual three-speed Ethernet controllers supporting IEEE 802.3 standards
• Built-in security engine handling DES, AES, RSA, and SHA algorithms
• DDR SDRAM memory controller with full error checking and correction

Applications

• Ethernet routers and switches
• Wireless LAN devices
• Network storage systems
• Industrial control equipment

Procurement Notes

Verify silicon revision compatibility before procurement. This document covers revision 1.1 silicon and earlier; parts ending in A or B require the MPC8347EA specifications. Confirm package type matches design requirements, as electrical characteristics differ between PBGA and TBGA variants. Ensure supply voltage tracking across VDD, AVDD, GVDD, LVDD, and OVDD rails during power sequencing.

Selection Notes

Select this component for applications requiring high integration of networking and security functions. Consider the TBGA package for higher DDR data rates up to 333 MHz compared to the PBGA limit of 266 MHz. Evaluate thermal dissipation requirements against typical power values provided in the datasheet tables. Verify software compatibility with existing Power Architecture implementations if migrating from older Freescale families.

Part Context

The MPC8347E series represents the next generation of the PowerQUICC II family, offering enhanced performance over the 603e-based predecessors. It serves as a system-on-chip solution for embedded networking and storage applications. The e300 core provides improved cache architecture and dynamic power management capabilities while maintaining software compatibility with legacy designs.

Replacement Considerations

MPC8349E offers similar functionality with dual PCI interfaces instead of single PCI.
