Product details

Motorola's VME/VSB microcomputers have outstanding features and functions, especially for embedded applications that require high performance and reliability. Here is a detailed description of its main features:

Core processor:

The MVME165 microcomputer uses Motorola's MC68040 microprocessor, a powerful processor that integrates an 8KB internal cache, floating point unit (FPU), and memory management unit (MMU). These features enable the MVME165 to efficiently handle complex data computation and memory management tasks to meet various high-performance computing requirements.

Memory configuration:

The MVME165 is equipped with either 4MB or 16MB DRAM for storing programs and data at runtime. In addition, it has a cache monitor to ensure cache consistency for local DRAM. This design ensures data consistency between cache and main memory, thereby improving system performance and stability.

Storage interface:

The microcomputer offers two 32-pin JEDEC standard slots for inserting EPROMs (erasable programmable read-only memory). This type of memory is typically used to store solidified programs or data that can be updated or modified without changing the hardware. In addition, there is a 28-pin JEDEC standard slot for installing TOD/NVRAM (time-Date Clock/non-volatile random access memory). TOD/NVRAM is used to hold critical system time and configuration information, maintaining data integrity even when the power is turned off.

Communication and interface:

The MVME165 integrates the MC68681 DURAT for serial input/output and software timing. This allows the microcomputer to communicate with other serial devices, such as modems, printers, etc. In addition, it is equipped with a local Resource Controller (LRC), which is responsible for the management of local control status registers, counters/timers, and local interrupt sources.

Bus interface:

The MVME165 has a complete VMEbus 32-bit master/slave interface, which enables it to communicate as a master or slave device in a VMEbus system. At the same time, it also contains the VMEbus interrupt processor, interrupter and system controller, as well as the global register set (MVME6000), which provides powerful support for VMEbus communication. In addition, the MVME165 has a complete VSB bus master/slave interface (MVSB2400), further expanding its communication capabilities.

Extension options:

Users also have the option to install the MVME714 transition module, which comes with two DB-25 connectors for connecting two RS232C devices to the MVME165. In addition, the MVME714M version offers a 2400 baud modem, which provides a console port and a port for a terminal/printer/modem, thus facilitating remote monitoring and data transfer.

To sum up, Motorola's VME/VSB microcomputer MVME165 with its powerful microprocessor, flexible memory configuration, rich storage interface and powerful communication capabilities, become the ideal choice in the field of embedded systems. Whether used in industrial automation, communications equipment or other high performance computing applications, it provides outstanding performance and stability.
