Description
Motorola MVME333S-2
Technical Specifications
- Processor: Onboard MC68010 CPU operating at 10 MHz.
- I/O Ports: 6 configurable serial I/O ports.
- Memory: 128 Kb dynamic RAM for data buffering.
- Firmware: Dual firmware slots for protocol flexibility.
Functional Features
- Multi-Protocol Support: Configurable for synchronous or asynchronous communication using RS-232C or RS-422 electrical standards.
- High-Speed Asynchronous Transfer: Built-in firmware supports bidirectional asynchronous protocols on all six channels simultaneously at baud rates up to 9600.
- Direct Memory Access (DMA): Features high-speed bidirectional DMA on two channels, enabling synchronous protocol transfers at speeds up to 1 Mb/s.
- Advanced Communication Interfaces: Supports multiple protocols including Ethernet, RS-232, and RS-485.
Application Scenarios
Widely utilized in embedded systems, industrial automation, communication equipment, military electronics, avionics, satellite communications, and robotic control systems.
Performance Parameters
- Asynchronous Baud Rate: Up to 9600 baud (bidirectional across all channels).
- Synchronous Transfer Rate: Up to 1 Mb/s (via DMA on dual channels).
- Data Buffer Capacity: 128 Kb dynamic RAM ensures stable data throughput.
Material Composition
Constructed using industrial-grade multi-layer printed circuit boards (PCBs), high-reliability integrated circuits, dynamic random-access memory, and precision communication transceiver components.
Structural Characteristics
Designed as a standard VMEbus intelligent communication controller board, featuring high-density backplane connectors and front-panel serial communication interfaces.
Working Principle
The onboard MC68010 CPU and firmware manage communication tasks. In asynchronous mode, the CPU handles data packaging and unpacking. In synchronous mode, the high-speed DMA directly transfers data between memory and communication ports, reducing CPU overhead and achieving 1 Mb/s throughput.
