Description
Technical & Performance Parameters
- Processor: MPC603 PowerPC RISC processor
- Main Memory: 32MB ECC DRAM
- Storage: 4MB on-board Flash memory for boot firmware
- Expansion: Dual PMC mezzanine card slots conforming to IEEE P1386.1 standard
- Bus Interface: VMEbus A32/D32, Universe I VME bridge ASIC
- Communication: Two independent asynchronous serial ports, optional 10/100 Ethernet
- Operating Temperature: 0°C ~ 70°C
- Form Factor: Standard 6U VME single slot
Functional Features
- RISC architecture brings higher instruction throughput compared with MC68040 series
- PMC expansion enables flexible addition of network, serial, and analog I/O mezzanine cards
- ECC memory protection detects and corrects single-bit memory errors
- Supports VxWorks, Linux and other PowerPC-targeted real-time operating systems
Working Principle
PowerPC processor executes operating system and control applications. Universe I ASIC serves as bridge between local PCI bus and VME backplane. PMC slots extend peripheral functions, realizing high-speed I/O expansion without occupying extra VME slots.
Application Scenarios
Industrial control system upgrades, radar auxiliary processing units, automated test platforms, transportation control systems.
Installation Requirements & Precautions
- Match PMC card voltage signaling standard before installation
- Maintain sufficient airflow around PMC modules to avoid thermal throttling
- ESD protection is mandatory during module assembly
