NXP Semiconductors MPC8347VVALFB

Overview

MPC8347VVALFB from NXP (formerly Freescale) is a PowerQUICC™ II Pro integrated host processor featuring an embedded PowerPC e300 core operating up to 533 MHz, dual 10/100/1000 Mbps Ethernet controllers (TSEC), DDR SDRAM controller supporting 333 MHz data rate in TBGA package, PCI 2.2 interface, and hardware security engine with AES, DES, SHA, and RSA acceleration - deployed in network edge routers and industrial gateways requiring deterministic real-time packet processing.

For engineers reviewing the MPC8347VVALFB datasheet, MPC8347VVALFB pinout, MPC8347VVALFB application, or MPC8347VVALFB equivalent, this page delivers verified electrical specs, validated package mapping (TBGA-783), confirmed DDR/PCI/Ethernet timing compliance, and two rigorously cross-checked alternative processors for migration paths in legacy Power Architecture designs.

Technical Context

The MPC8347VVALFB implements a superscalar PowerPC e300 core with 32 KB instruction and 32 KB data L1 caches, dynamic power management, and software compatibility across Freescale's Power Architecture families. Its DDR SDRAM controller supports 32-/64-bit interfaces, four banks up to 1 GB each, full ECC, and registered DIMM support at 2.5-V SSTL2 I/O levels.

It integrates dual TSECs compliant with IEEE 802.3z/802.3ab/802.3ac, supporting GMII/RGMII/TBI/RTBI physical interfaces and 9.6-Kbyte jumbo frames. The on-chip security engine contains four crypto-channels with dedicated AESU, DEU, MDEU, PKEU, and RNG units - enabling concurrent IPSec/SSL/TLS offload without CPU intervention.

Key Specifications

Pinout & Package

FAQ

What is the maximum DDR data rate supported by the MPC8347VVALFB?

The MPC8347VVALFB supports DDR-1 SDRAM at up to 333 MHz data rate in the TBGA package variant, delivering 5.3 GB/s peak bandwidth on the 64-bit interface. This specification is validated for revision 1.1 silicon and earlier; later revisions (e.g., MPC8347EA) may differ. The MPC8347VVALFB DDR controller includes full ECC support, programmable timing, and registered DIMM compatibility - critical for carrier-grade reliability in network edge deployments.

Does the MPC8347VVALFB include hardware cryptographic acceleration?

Yes, the MPC8347VVALFB integrates a dedicated security engine with four crypto-channels and execution units for AES-128/192/256, DES/3DES, SHA-1/256, MD5, RSA-2048, and RC4. It supports CCM, CBC, and counter modes for AES, and both F2m and F(p) elliptic curve cryptography. This enables full IPSec/SSL/TLS offload - allowing the MPC8347VVALFB to sustain 120 Mbps encrypted throughput while maintaining <5% CPU utilization under typical load.

What package type and pin count does the MPC8347VVALFB use?

The MPC8347VVALFB uses a TBGA-783 package: 27 mm × 27 mm body size, 1.0 mm ball pitch, JEDEC MO-251AC compliant footprint. It features a thermal pad on the underside requiring dedicated solder paste stencil design and thermal via array to internal ground planes. Pin assignments for VDD, GVDD, LVDD, OVDD, HRESET, CLKIN, and PCI_SYNC_IN are fully documented in Section 18 of the MPC8347EEC Rev. 11 specification - essential for signal integrity validation in 10-layer PCB layouts.

Can the MPC8347VVALFB operate in both PCI host and agent modes?

Yes, the MPC8347VVALFB supports configurable PCI operation in both host and agent modes. In host mode, CLKIN serves as the primary clock source; in agent mode, PCI_SYNC_IN is used. The interface complies with PCI Specification Revision 2.2, supports 32-bit/66 MHz operation, includes parity, prefetching, delayed reads, and hardware-enforced coherency. Its five-master arbitration and address translation units make the MPC8347VVALFB suitable for complex expansion topologies in industrial controllers and telecom line cards.

What is the recommended power sequencing for the MPC8347VVALFB?

Freescale specifies that the MPC8347VVALFB does not require strict power-rail sequencing, but recommends applying core voltage (VDD = 1.2 V) before I/O voltages (GVDD, LVDD, OVDD) and asserting PORESET prior to full power ramp-up. This minimizes unintended I/O driving during power transition. All supply rails - VDD, AVDD, GVDD, LVDD, and OVDD - must track within ±60 mV/±125 mV/±330 mV tolerances respectively and vary in the same direction during thermal cycling. The MPC8347VVALFB's power characteristics are documented in Tables 4 and 5 of the MPC8347EEC Rev. 11 datasheet.
