Description
Motorola MVME16201
Technical Specifications
- Microprocessor: 32 MHz MC68040 enhanced 32-bit processor featuring an 8KB cache, Memory Management Unit (MMU), and Floating-Point Unit (FPU).
- Memory: 4MB shared DRAM (expandable up to 16MB) and 512KB SRAM with battery backup.
- Storage: 1MB Flash memory for onboard monitor/debugger firmware.
- Interfaces: Dual serial ports (EIA-232-D and EIA-232-D/EIA-422), four IndustryPack ports, optional Ethernet, and SCSI.
Functional Features
- Supports VMEbus A32/D64 block transfers and system controller functionality.
- Features high-performance DMA for local bus memory burst cycles.
- Includes six 32-bit timers and a watchdog timer for system reliability.
- Provides remote RESET, ABORT, and STATUS control functions via the VMEbus.
Application Scenarios
Widely deployed in industrial automation, data acquisition stations, large-scale equipment control nodes, and telecommunications switching systems.
Performance Parameters
- Bus Interface: A32/D64 VMEbus master/slave interface.
- Power Requirements: +5V at 3.5A typical (4.5A max), ±12V at 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 optional conformal coating for protection against harsh environments.
Structural Characteristics
Standard 6U VME form factor (233.35mm x 160.00mm) with P1/P2 backplane connectors, front panel status LEDs, and manual reset/abort pushbuttons.
Working Principle
The MC68040 CPU manages local memory and peripherals via a high-speed local bus. The VMEChip2 ASIC arbitrates and routes data across the VME backplane, while IndustryPack interfaces provide direct connections to external physical I/O modules.
Installation Requirements
- Insert into a standard 6U VME chassis with proper card guides and secure with front panel screws.
- Requires unobstructed forced air cooling (typically 100 CFM airflow).
- Ensure strict adherence to backplane power (+5V, ±12V) and grounding specifications.
Usage Precautions
- Strictly observe ESD (Electrostatic Discharge) handling procedures during installation.
- Never insert or remove the board while system power is applied.
- Periodically clean heat sinks and fans to prevent thermal throttling.
