Description
Motorola MVME147SRF
Technical Specifications:
- Brand: Motorola
- Model: MVME147SRF
- Core Processor: MC68030 Microprocessor and MC68882 Floating-Point Coprocessor
- Memory: Shared DRAM (without parity) and 2KB CMOS RAM with battery backup
- Storage: Four ROM/PROM/EPROM sockets (16-bit wide)
Functional Features:
- Powerful Floating-Point Computing: Integrates an MC68882 coprocessor specifically designed to accelerate complex mathematical and engineering calculations.
- Rich I/O Interfaces: Provides four RS-232C serial ports, a Centronics printer port, and a SCSI bus interface with DMA channels.
- System-Level Control: Features VMEbus interrupter, system controller, and master interface functions, supporting A32/D32 and A24/D16 addressing.
- Hardware Watchdog: Incorporates a tick timer and a watchdog timer to prevent system deadlocks.
Application Scenarios:
Primarily used in medical imaging equipment (such as GE LOGIQ series ultrasound systems), industrial automation control, communication equipment, and avionics systems.
Performance Parameters:
- Bus Compatibility: Fully compatible with 32-bit VMEbus (P1 and P2 backplanes).
- Data Retention: Features a battery-backed clock/calendar and CMOS RAM to ensure critical configurations are not lost during power outages.
Material Composition:
Manufactured using high flame-retardant, high-Tg industrial-grade PCB materials. Critical integrated circuits undergo strict derating design to ensure thermal stability during long-term operation.
Structural Characteristics:
Standard Dual High VME module dimensions. The front panel is equipped with SCON, DUAL, FAIL, and STATUS indicator LEDs, as well as physical reset and abort switches.
Working Principle:
The MC68030 processor interacts with external modules via the VMEbus interface, utilizes the MC68882 to process floating-point instructions, and employs a DMA controller to achieve high-speed data transfer between SCSI devices and memory, thereby reducing the CPU burden.
Installation Requirements:
Must be installed in a standard VME chassis. Forced air cooling requires an inlet air temperature between 0°C and 55°C, with a minimum airflow of 10 CFM across the module.
Usage Precautions:
This module does not have an Ethernet interface (which distinguishes it from the MVME147S). Strictly adhere to anti-static protocols when replacing the on-board CMOS battery. Ensure the cooling fans in the chassis are operating normally to prevent thermal throttling.
