Description
Motorola MVME2603-1121C
Technical Specifications
- Core Architecture: PowerPC 603 32-bit microprocessor.
- Memory Management: Complete Memory Management Unit (MMU) supporting virtual memory.
- I/O Interfaces: Supports synchronous/asynchronous serial ports, parallel port, SCSI, and Ethernet.
- Debug Tools: Built-in PPCBug debugger supporting Ethernet MAC address configuration via CNFG command.
Functional Features
- High Integration: Packs rich standard computer peripheral functions within a single-slot VME package.
- Flexible Upgrades: Flexible mezzanine architecture allows easy upgrades in memory and I/O functionality.
- Network Communication: Each module is assigned a unique Ethernet MAC address ($08003E2xxxxx) stored in SROM.
Application Scenarios
Applicable in Distributed Control Systems (DCS), Programmable Logic Controllers (PLC), radar systems, and complex test and measurement equipment.
Performance Parameters
- Power Requirements: +12V DC (±5%), typical 250mA, max 1A; -12V DC (±5%), typical 100mA, max 250mA.
- Bus Support: VMEbus interrupter, interrupt handler, and DMA for fast local memory/VMEbus transfers.
Material Composition
Industrial-grade flame-retardant PCB substrate with high-reliability surface-mount soldering processes and strictly screened critical chips.
Structural Characteristics
Standard 6U VME form factor with front panel connectors (e.g., AUI, SCSI, serial ports) and rear P1/P2 connectors for backplane communication.
Operating Principle
The processor interacts with on-board peripherals via the local bus and utilizes the DMA controller to achieve high-speed data transfer between local memory and the VME bus, minimizing CPU overhead.
Installation Requirements
When installing transition modules (e.g., MVME712M or MVME761), ensure the P2 connector is properly aligned and secured using the appropriate length standoffs.
Usage Precautions
If the Ethernet address in the SROM is lost, it must be restored using the address printed on the label located behind the base board PMC connector protection area. Modifying the factory-assigned unique MAC address is strictly prohibited.
