Description

MOTOROLA  MVME162-262  high-performance VME embedded controller module

Processor: It adopts a 25MHz MC68040 enhanced 32-bit microprocessor, equipped with 8KB cache, MMU (Memory Management Unit) and FPU (Floating-point Unit), capable of quickly handling complex algorithms and real-time tasks.
Memory:
Standard memory: Usually, it comes with 4MB of shared DRAM as standard, supporting expansion up to 16MB. Some models can be increased to 64MB by expanding the mezzanine, which can meet the memory capacity requirements of different applications.
Backup memory: Equipped with 512KB of SRAM with a spare battery, it ensures that critical data is not lost in case of power failure.

Storage and Interface:
Storage: It is equipped with 1MB of built-in Flash memory for storing on-board monitors, debuggers or user-installed firmware. Some models have a flash memory capacity of 2MB and also support EPROM and Flash expansion, allowing users to increase storage capacity according to their actual needs.
Communication interface: It provides 4 serial communication ports, including EIA-232 and EIA-422/485 standards, which can meet different serial communication requirements. It is equipped with 4 IndustryPack® interfaces, each of which has a DMA channel, facilitating the connection of various IndustryPack modules to achieve different functional expansions, such as I/O control, analog and digital signal processing, etc. In addition, a SCSI bus interface can be optionally equipped, featuring a 32-bit local bus burst DMA, which can be used to connect external storage devices or other SCSI devices.

Bus and Scalability
Bus standard: Compatible with the VME bus standard, supports A32/D64 master/slave interfaces, has strong data transmission capability, and can perform high-speed data interaction with other VME bus devices.
Interrupt handling: Equipped with four levels of requesters, seven levels of interrupters and interrupt handling programs, it can effectively handle various interrupt events and ensure the real-time responsiveness of the system. Moreover, functional modules can be added by expanding the slots, which is convenient for users to expand the functions according to specific application scenarios.

Other features:
Environmental adaptability: The operating temperature range is -40 °C to + 85°C, the relative humidity is 5% to 95% (without condensation), and the seismic performance complies with the MIL-STD-810 standard. It can work stably in harsh industrial environments.
Power supply and power consumption: Supports wide-range DC input of + 5V and ±12V, with a typical power consumption of 20W. It can adapt to different power supply conditions and meet the requirements of distributed control architectures.
