Description
Motorola MVME162-723
Technical Specifications
- Processor: Enhanced 32-bit microprocessor (MC68040 series).
- Bus Interface: Supports A32/D64 VME master/slave interfaces and local bus burst DMA.
- Storage: Onboard DRAM, battery-backed NVRAM, and TOD clock.
- Communication: Multiple serial ports, optional 10Base-T Ethernet and SCSI.
Functional Features
- High-Speed Data Transfer: Supports VMEbus D64 and local bus memory burst cycles.
- Multi-Port Serial Communication: Provides multiple serial ports routed through front-panel RJ-45 connectors.
- Onboard Diagnostics: Includes built-in debugger and diagnostic firmware (162Bug) to simplify troubleshooting.
- Remote Management: Supports remote RESET/ABORT/STATUS control functions.
Application Scenarios
Suitable for telecommunications network equipment, large data center monitoring, aerospace ground systems, and complex military equipment control.
Performance Parameters
- Power Consumption: Typical 20W, supports +5V and ±12V wide-range DC input.
- Task Switching: Task switching latency is below 50μs.
Material Composition
Industrial-grade FR-4 substrate populated with Motorola-certified high-performance ASIC chips.
Structural Characteristics
Double-high VME module design, equipped with high-density backplane connectors and front-panel RJ-45 network/serial interfaces.
Working Principle
Utilizes the onboard high-performance DMA controller to complete high-speed data transfers between the VME bus and local memory without occupying CPU resources.
Installation Requirements
- Ensure unobstructed chassis airflow; a minimum of 10 CFM and 490 LFM per slot is recommended.
- Connect front-panel RJ-45 serial cables correctly.
Usage Precautions
- In high EMI environments, add ferrite core filters to interfaces if serial data packet loss occurs.
- Do not use alcohol-based solvents for cleaning; use a mixture of isopropyl alcohol and deionized water.
