MOTOROLA MVME147-010 single-board computer

MOTOROLA MVME147-010 single-board computer

Processor: It adopts the MC68030 enhanced 32-bit microprocessor with 16, 25 or 33.33MHz, featuring on-board cache for instructions and data, which can increase the processor efficiency by 20% – 40%. The MC68030 also features a complete memory management unit (MMU), providing software protection and virtual memory functions.
Coprocessor: Equipped with 16, 25 or 33.33MHz MC68882 floating-point coprocessors, it supports full floating-point operations, trigonometric operations, etc., and is suitable for instrument functions and built-in constant calculations.

Memory: There are 4, 8, 16 or 32MB shared DRAM, programmable peering, as well as 4K x 8 SRAM and a battery-powered clock to ensure that clock information and some key data can still be retained after the system is powered off.
Storage interface: Four 28/32-pin ROM/PROM/EPROM/EEPROM 16-bit wide sockets are provided, which can be used to expand storage or store system programs, configuration information, etc.

System interface: It is equipped with A32/D32 VMEbus master/slave system interfaces, which can be conveniently connected and communicated with other VMEbus devices, achieving system expansion and integration.

Communication port: It has four EIA-232-D serial communication ports, which can be used for serial data transmission with other devices, such as connecting external sensors, modems, etc. It also has an Ethernet transceiver interface, achieving Ethernet connection through a jack connector, allowing the circuit board to interface with other Mark VI, Mark VIe or EX2100 excitation controllers as well as maintenance and operator stations.

Other interfaces: Equipped with a Centronics compatible printer port, which can be connected to a printer to output data or reports; Two 16-bit timers and a watchdog timer for timing control and system monitoring; The SCSI bus interface with DMA can be connected to SCSI devices such as hard disks and tape drives to achieve high-speed data transmission.
