Description
Configuration: • 25 MHz MC68030 Microprocessor • 25 MHz MC6888 Co-Processor • 16 MB DRAM • (2) Bios Chip • Ethernet Transceiver Interface • SCSI Bus Interface Features: • MC68030 Enhanced 32-bit Microprocessor • Four 28/32-pin ROM/PROM/EPROM/EEPROM Sockets • Four EIA-232-D Serial Communications Ports • 4K x 8 SRAM and Time-of-Day Clock with Battery • On-Board Debugger and Diagnostic Firmware The MVME147 series offers one of the world's finest VMEbus single-board computers. The on-board resources and peripheral controllers eliminate the need for additional modules in the VMEbus backplane thus reducing costs and freeing up valuable bus slots for additional functions. The MVME147 series features an MC68030 enhanced 32-bit microprocessor. The MC68030 was the first general purpose microprocessor with on-chip cache memory for both instructions and data which increases the processor's efficiency by 20 to 40 percent. The MC68030 features a complete memory management unit (MMU) which provides the software protection and virtual memory functions critical to many applications.
The role of the power module is the conversion of voltage, which can convert AC or direct current into the AC or direct current you need. For example, the mains 220V alternating current (AC) is converted into 5V direct current (DC), because the AC 220V electricity is high voltage, and the electronic products are low voltage power supply, which requires a conversion device to convert the AC 220V voltage into low voltage. For example, in the motor vehicle sometimes need to be converted to 220V alternating current to use, then this will become a low voltage to high voltage, because the voltage of the motor vehicle is generally relatively low. In short, it is similar to a mobile phone charger, your mobile phone is out of power, to plug or charge to normal use, but you can not directly connect to 220V use, because the mobile phone will burn, so you need a special conversion device to convert the voltage required by the mobile phone. A power supply module is a power supply that can be mounted directly on a printed circuit board and is characterized by providing power for application-specific integrated circuits (ASics), digital signal processors (DSPS), microprocessors, memory, field programmable gate arrays (FPgas), and other digital or analog loads. In general, such modules are called load (POL) power supply systems or point-of-use power supply systems (PUPS). Because of the advantages of the modular structure, the module power supply is widely used in switching equipment, access equipment, mobile communication, microwave communication, optical transmission, routers and other communication fields and automotive electronics, aerospace and so on.
