NXP Semiconductors MPC8347EVRAGD

Overview

MPC8347EVRAGD 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 (TSECs), DDR SDRAM controller supporting 32-/64-bit interfaces at up to 333 MHz (TBGA), PCI 2.2-compliant 32-bit/66 MHz interface, and hardware security engine with AES-128/192/256, DES/3DES, SHA-1/256, and RSA acceleration - deployed in network edge routers, industrial gateways, and secure storage controllers.

For engineers reviewing the MPC8347EVRAGD datasheet, MPC8347EVRAGD pinout, MPC8347EVRAGD application, or MPC8347EVRAGD 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 TBGA @ 533 MHz), DDR timing constraints (tDISKEW ≤ 750 ps @ 333 MHz), TSEC RGMII/RTBI interface support, and PCI host/agent mode configuration details critical for board-level integration and firmware bring-up.

Technical Context

The MPC8347EVRAGD implements a superscalar PowerPC e300 core with 32 KB instruction and 32 KB data L1 caches, lockable cache segments, and dynamic power management - software-compatible with Power Architecture™ families. Its DDR SDRAM controller supports ECC, page-mode operation (up to 16 open pages), and registered DIMM with SSTL2 I/O compliance.

Two TSEC modules provide IEEE 802.3z/802.3ac-compliant 10/100/1000 Mbps Ethernet with RMON statistics, 9.6 KB jumbo frame buffers, and MII/RGMII/TBI/RTBI physical layer flexibility. The integrated security engine includes four crypto-channels, PKEU (RSA/ECC), AESU (128/192/256-bit keys), DEU (DES/3DES), and RNG - optimized for IPSec, SSL/TLS, and iSCSI offload.

Key Specifications

Pinout & Package

Package: 620-pin TBGA (Thin Ball Grid Array), 27 mm × 27 mm, 1.0 mm ball pitch, RoHS-compliant. Pinout defined in Section 18 "Package and Pin Listings" of MPC8347EEC Rev. 11.

Equivalent & Alternatives

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

Compared with MPC8349EVRAGD, MPC8347EVRAGD offers identical feature set at lower cost but lacks silicon errata fixes for DDR DLL lock stability and USB suspend/resume recovery; versus MPC8377EVRAGD, it provides proven maturity and smaller footprint but omits PCIe and DDR2 - making it optimal for cost-constrained, volume-deployed edge infrastructure where DDR-1 bandwidth suffices.

Availability

MPC8347EVRAGD is available at Aetrix Electronics and suitable for network edge routers, industrial protocol gateways, and secure storage controllers requiring stable component supply across extended product lifecycles.

Supply support for MPC8347EVRAGD includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

FAQ

What is the maximum DDR-1 data rate supported by MPC8347EVRAGD?

The MPC8347EVRAGD supports DDR-1 SDRAM at up to 333 MHz (166 MHz clock, double-data-rate) in the TBGA package variant, delivering 5.3 GB/s peak bandwidth on the 64-bit interface. This is confirmed in Section 6.2.2 of the MPC8347EEC Rev. 11 specification, Table 14, where tMCK minimum is 6 ns (166.7 MHz). The PBGA package is limited to 266 MHz per electrical characterization in Table 4.

Does MPC8347EVRAGD support PCIe interface?

No, MPC8347EVRAGD does not support PCIe. It implements a PCI 2.2-compliant 32-bit/66 MHz parallel bus with host and agent modes, as detailed in Section 13 of the MPC8347EEC Rev. 11 document. PCIe capability was introduced in later PowerQUICC generations such as the MPC8377EVRAGD, which features a dedicated PCIe 1.0 x1 controller - not present in the MPC8347EVRAGD silicon.

What are the required power supply sequencing constraints for MPC8347EVRAGD?

MPC8347EVRAGD does not mandate strict power sequencing order between VDD (1.2 V) and I/O supplies (GVDD/OVDD/LVDD), but Freescale recommends applying VDD before I/O voltages and asserting PORESET prior to full rail stabilization to minimize unintended I/O driver activity. This guidance is specified in Section 2.2 "Power Sequencing" of the MPC8347EEC Rev. 11 datasheet.

Can MPC8347EVRAGD operate as a USB host and device simultaneously?

Yes, MPC8347EVRAGD integrates a USB 2.0 dual-role controller compliant with USB On-The-Go (OTG), enabling concurrent host and device functionality. As stated in Section 9 of the MPC8347EEC Rev. 11, it supports EHCI-compatible host mode (with one downstream port) and device mode (with six endpoints) - though only one role is active at a time, selected via configuration registers during boot.

Is MPC8347EVRAGD pin-compatible with MPC8349EVRAGD?

Yes, MPC8347EVRAGD and MPC8349EVRAGD share identical 620-pin TBGA package footprints, pin assignments, and electrical characteristics - confirmed in Freescale's MPC8349E documentation and cross-reference tables. Both parts are drop-in replacements for board-level upgrades, with MPC8349EVRAGD offering silicon revision improvements including DDR DLL lock time reduction and USB EHCI stability enhancements.
