For engineers reviewing the MPC8347EVVALFB datasheet, MPC8347EVVALFB pinout, MPC8347EVVALFB application, or MPC8347EVVALFB equivalent, this page delivers verified electrical specs (VDD = 1.2 V ±60 mV, GVDD = 2.5 V ±125 mV), thermal power data (up to 3.6 W typical at 533 MHz/TBGA), DDR timing constraints (tDISKEW ≤750 ps @333 MHz), TSEC RGMII/RTBI interface support, and PCI host/agent mode configuration details critical for board-level validation and firmware bring-up.

Technical Context

The MPC8347EVVALFB implements a superscalar e300 core with 32-Kbyte instruction and 32-Kbyte data L1 caches (lockable portion), dynamic power management, and software compatibility across Power Architecture™ families. Its DDR SDRAM controller supports ECC, page-mode operation (up to 16 open pages), and registered DIMM with 2.5-V SSTL2 I/O compliance.

Two TSEC modules provide IEEE 802.3/802.3u/802.3z-compliant 10/100/1000-Mbps Ethernet with RMON statistics, 9.6-Kbyte jumbo frames, and MII management; the integrated security engine includes four crypto-channels, PKEU (RSA/ECDSA up to 2048-bit), AESU (128/192/256-bit keys), and RNG - all accessible via descriptor-based DMA transfers.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar integrated host processor applications.

Compared with MPC8347EVVALFB, MPC8349EVVAGB offers higher clock headroom within identical pinout and power envelope, while MPC8377ERVAA trades one Ethernet port for SerDes and PCIe - making it better suited for infrastructure aggregation than edge routing.

FAQ

What is the maximum DDR data rate supported by the MPC8347EVVALFB?

The MPC8347EVVALFB supports DDR-1 SDRAM at up to 333 MHz data rate in TBGA packages (e.g., MPC8347EVVALFB), confirmed in Section 6 of the Hardware Specifications Rev. 11. This corresponds to 667 MT/s transfer rate with 32- or 64-bit bus widths. The PBGA variant is limited to 266 MHz. MPC8347EVVALFB's DDR controller includes full ECC, page-mode support (up to 16 open pages), and registered DIMM compatibility.

Does the MPC8347EVVALFB support PCI Express?

No, the MPC8347EVVALFB does not support PCI Express. It implements a PCI Specification Revision 2.2-compliant 32-bit/66-MHz parallel bus interface with host bridge and agent capabilities. PCI Express support was introduced in later PowerQUICC III (MPC85xx) and QorIQ (T-series) families. MPC8347EVVALFB's PCI interface provides parity, selectable coherency, and address translation units - but lacks PCIe's serial differential signaling, link training, or transaction layer.

What are the power supply requirements for the MPC8347EVVALFB core and I/O rails?

The MPC8347EVVALFB requires five regulated supplies: VDD = 1.2 V ±60 mV (core), AVDD = 1.2 V ±60 mV (PLL), GVDD = 2.5 V ±125 mV (DDR I/O), LVDD = 2.5 V or 3.3 V ±330 mV (TSEC), and OVDD = 3.3 V ±330 mV (PCI/local bus/I2C/JTAG). Per Section 2.1.2, all supplies must track directionally during ramp-up; GVDD must remain within ±50 mV of DRAM GVDD at all times.

How many Ethernet ports does the MPC8347EVVALFB integrate, and what physical layer interfaces are supported?

The MPC8347EVVALFB integrates two independent three-speed (10/100/1000 Mbps) Ethernet controllers (TSECs). Each supports GMII/RGMII for 1000BASE-X, MII for 10/100BASE-TX, and TBI/RTBI for fiber interfaces - all compliant with IEEE 802.3/802.3u/802.3z standards. MPC8347EVVALFB also provides MII management interface for PHY control and supports 9.6-Kbyte jumbo frames with RMON statistics collection.

Is the MPC8347EVVALFB pin-compatible with other PowerQUICC II Pro processors like the MPC8349E?

Yes, the MPC8347EVVALFB is pin-compatible with the MPC8349E in identical TBGA-783 packaging (e.g., MPC8349EVVAGB), sharing identical pin functions, power domains, and thermal pad layout. Freescale explicitly states functional and register-level compatibility across the MPC8347E/MPC8349E family in the Reference Manual. However, MPC8349E supports higher core frequencies (up to 800 MHz) and requires revision 3.0 silicon documentation for full specification alignment.
