Description
Motorola MVME162-020
Technical Specifications
- Microprocessor: 25 MHz MC68040 with 8KB cache, MMU, and integrated FPU.
- Memory: 4MB DRAM (expandable to 16MB) and 512KB SRAM with battery backup.
- Storage: 1MB Flash memory for firmware and 32-pin PLCC EPROM socket.
- Interfaces: Two serial ports (EIA-232-D and EIA-232-D/EIA-530), optional Ethernet, and optional SCSI.
Functional Features
- Supports VMEbus A32/D64 block transfers for high-speed DMA.
- Features four IndustryPack ports for flexible I/O expansion.
- Includes six 32-bit timers and a watchdog timer.
- Provides remote RESET, ABORT, and STATUS control capabilities.
Application Scenarios
Widely deployed in factory automation, process control systems, telecommunications, and semiconductor manufacturing equipment.
Performance Parameters
- Bus Interface: A32/D64 VMEbus master/slave with system controller functionality.
- Power Requirements: +5V (3.5A typical, 4.5A max), ±12V (100mA max).
- Operating Temperature: 0°C to +55°C with forced air cooling.
Material Composition
Constructed with industrial-grade multi-layer PCBs, high-reliability CMOS components, and a conformal coating option for harsh environments.
Structural Characteristics
Standard 6U VME form factor (233.35mm x 160.00mm) with P1/P2 backplane connectors, front panel LEDs, and pushbutton switches.
Working Principle
The MC68040 CPU manages local memory and peripherals via a local bus, utilizing the VMEChip2 ASIC to arbitrate and transfer data across the VME backplane to other system modules.
Installation Requirements
- Must be inserted into a 6U VME chassis with proper card guides.
- Requires unobstructed forced air cooling (typically 100 LFM airflow).
- Front panel screws must be tightened to secure the board against vibration.
Usage Precautions
- Always observe strict ESD (Electrostatic Discharge) handling procedures.
- Never insert or remove the board while system power is applied.
- Ensure the SRAM backup battery is functional to prevent data loss.
