MPC8347CVRADDB

Overview

The MPC8347CVRADDB is a PowerQUICC II Pro integrated host processor based on the e300 core. It features a 32-bit superscalar architecture with up to 667 MHz operation, 32 KB instruction and data caches, and dynamic power management. The SoC integrates dual three-speed Ethernet controllers (10/100/1000 Mbps), a PCI interface compliant with Rev 2.3, DDR1/DDR2 SDRAM memory controller supporting ECC, and dual USB 2.0 controllers. A dedicated security engine supports DES, 3DES, AES, RSA, and SHA algorithms. Additional peripherals include a local bus controller, DUART, I2C, SPI, GPIO, and four-channel DMA.

Feature Summary

• Integrated high-performance e300 processor core with floating-point support
• Dual three-speed Ethernet controllers for network connectivity
• Hardware-accelerated security engine for encryption and authentication
• Comprehensive peripheral set including PCI, USB, and Local Bus

Applications

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

Procurement Notes

Verify silicon revision compatibility before integration; this document covers revision 3.x silicon and later. Confirm package type and speed grade match design requirements. Check for specific ordering suffixes that define temperature range or pin count. Ensure power sequencing adheres to specifications to prevent excessive current draw during startup. Validate software compatibility with existing Power Architecture implementations.

Selection Notes

Select based on required clock frequency and memory interface type (DDR1 vs DDR2). Verify I/O voltage levels for Ethernet and PCI interfaces match system components. Consider thermal dissipation capabilities relative to operating frequency and load. Ensure sufficient cache size and DMA channels for application throughput. Evaluate security engine requirements against protocol standards like IPsec or SSL/TLS.

Part Context

The MPC8347CVRADDB belongs to the NXP PowerQUICC II Pro family, designed for embedded networking and communications applications. It builds upon the previous PowerQUICC II series with enhanced performance and integration. The device targets cost-effective solutions for small-to-medium businesses and consumer applications requiring high processing power and connectivity.

Replacement Considerations

NXP recommends using the T1013 (Power Architecture) or LS1012/LS1023 (Arm Architecture) families for new designs as the MPC8347E is not recommended for new designs.
