NXP Semiconductors MPC8347EVVAJFB

Overview

MPC8347EVVAJFB from Freescale Semiconductor is a PowerQUICC™ II Pro integrated host processor featuring an embedded PowerPC e300 core operating up to 667 MHz, dual 10/100/1000 Mbps Ethernet controllers (TSEC), DDR SDRAM controller supporting 32-/64-bit interfaces at up to 333 MHz (TBGA), PCI 2.2 interface, and hardware security engine with AES-128/192/256, DES/3DES, SHA-1/256, and RSA acceleration. It targets network edge routers, industrial gateways, and secure embedded communications systems.

For engineers reviewing the MPC8347EVVAJFB datasheet, MPC8347EVVAJFB pinout, MPC8347EVVAJFB application, or MPC8347EVVAJFB equivalent, key selection criteria include its 667-MHz e300 core performance, dual TSEC compliance with IEEE 802.3z/ac, DDR-1 timing programmability, PCI host/agent mode flexibility, and integrated crypto-channel architecture for IPSec/SSL offload - all validated for TBGA-783 packaging and revision 1.1 silicon.

Technical Context

The MPC8347EVVAJFB implements a superscalar PowerPC e300 core with 32-KB instruction and 32-KB data L1 caches, lockable cache segments, and dynamic power management. Its DDR SDRAM controller supports four banks (up to 1 GB each), ECC, page mode (16 open pages), and registered DIMM compatibility with 2.5-V SSTL2 I/O.

Two TSEC modules provide full-duplex GMII/RGMII/TBI/RTBI and MII interfaces, each with 2-KB TX/RX FIFOs, jumbo frame (9.6 KB) support, RMON statistics, and MII management. The security engine integrates four crypto-channels with dedicated execution units for AES, DES/3DES, SHA/MD5, PKEU (RSA/ECC), and ARC4, enabling concurrent multi-algorithm processing.

FAQ

What is the maximum DDR data rate supported by the MPC8347EVVAJFB?

The MPC8347EVVAJFB supports DDR-1 SDRAM at up to 333 MHz data rate in TBGA-783 package configurations, delivering 5.3 GB/s peak bandwidth on the 64-bit interface. This is validated for revision 1.1 silicon and requires 2.5-V SSTL2-compatible DRAM components with proper termination to MVREF. The controller does not support DDR2 or higher generations.

Does the MPC8347EVVAJFB support PCIe or SATA interfaces?

No, the MPC8347EVVAJFB does not include PCIe or SATA interfaces. It features a PCI 2.2-compliant parallel bus interface and dual three-speed Ethernet (TSEC) controllers, but lacks integrated SerDes blocks required for PCIe or SATA physical layers. For SerDes-based connectivity, consider the MPC8377ERVAAJFB variant within the same PowerQUICC II Pro family.

How many crypto algorithms can the MPC8347EVVAJFB execute concurrently?

The MPC8347EVVAJFB security engine supports concurrent execution of up to four distinct cryptographic operations - one per crypto-channel - such as AES-128 encryption, SHA-256 hashing, RSA-2048 signature generation, and ARC4 stream cipher, all managed via descriptor chains. Each channel accesses dedicated execution units (AESU, MDEU, PKEU, AFEU) without resource contention.

What is the thermal design power (TDP) of the MPC8347EVVAJFB in typical operation?

The MPC8347EVVAJFB has a typical power dissipation of 3.0 W at 533 MHz core frequency and 333 MHz DDR interface in TBGA-783 package, with maximum power reaching 3.6 W under worst-case process and temperature conditions. Thermal solution design must accommodate junction temperatures up to 105°C and ensure case temperature remains below 70°C for continuous operation.

Is the MPC8347EVVAJFB pin-compatible with later revisions like MPC8347EA?

No, the MPC8347EVVAJFB (revision 1.1 silicon) is not pin-compatible with MPC8347EA/B variants (revision 3.0+ silicon). Revision 3.0 introduced DDR2 support, modified PLL/DLL timing, and updated power sequencing requirements, necessitating PCB layout changes. The MPC8347EVVAJFB datasheet explicitly states that revision 3.0 information is covered in the separate MPC8347EA Hardware Specifications document.
