Technical Specifications
The DVEP7447-50 uses the Freescale MPC7447A Power Architecture e600 processor. The DVEP7447/51-PbF variant operates with a core clock of 833 MHz and an MPX bus clock of 160 MHz. The board provides gigabit networking, serial maintenance ports, CompactFlash/IDE storage, and VME-PCI bridging. The 6U VME form factor provides central-resource capability for VME chassis systems.

Functional Features
The DVEP7447-50 delivers Power Architecture processing performance for embedded VME systems. It includes gigabit Ethernet networking, serial maintenance ports, CompactFlash and IDE storage interfaces, VME-PCI bridging, system memory, flash storage, and USB connectivity. The board is designed as a central resource for VME chassis, providing system controller functionality.

Application Scenarios
Embedded defense systems, industrial control platforms, transportation systems, and instrumentation equipment requiring VMEbus longevity and Power Architecture processing capability.

Material Composition
Constructed as a 6U VMEbus printed circuit board assembly with the MPC7447A processor, memory devices, networking controllers, and interface circuitry. The PbF suffix indicates a lead-free manufacturing process.

Structural Characteristics
6U VMEbus form factor. The board occupies a single VME slot and provides front-panel connectors for networking and serial interfaces, with rear VMEbus connectors for backplane communication.

Working Principle
The MPC7447A Power Architecture processor executes instructions from system memory. The VMEbus interface provides communication with other VME boards and the system controller. Onboard memory controllers manage DRAM and flash storage. Networking controllers handle gigabit Ethernet traffic. The VME-PCI bridge enables communication between the VMEbus and PCI-based peripherals.

Installation Requirements
Installation in a 6U VMEbus chassis. The board requires proper power supply voltages from the VME backplane. Cooling must be provided according to the thermal specifications of the MPC7447A processor. Configuration of the VMEbus address space and system controller functions must be performed according to the Densan manual.

Usage Precautions
The exact 50 variant configuration, including memory size, firmware, temperature rating, connector options, and board support package (BSP), must be confirmed from the official Densan ordering sheet. Do not assume interchangeability between the 50, 50A, and 50B variants without verifying the specific board label and release notes.
