Description
Motorola MVME162PA-252LSE
Technical Specifications
- Microprocessor: 25 MHz MC68040 enhanced 32-bit microprocessor with integrated 8KB cache, Memory Management Unit (MMU), and Floating-Point Unit (FPU).
- Main Memory: 16MB Synchronous Dynamic Random Access Memory (SDRAM) with hardware ECC protection.
- Storage Resources: 512KB battery-backed SRAM, 1MB Flash memory, and 8K x 8 NVRAM with battery-backed Time-of-Day (TOD) clock.
- Bus Interface: A32/D64 VMEbus master/slave interface with full system controller functionality.
Functional Features
- Second-Generation Petra ASIC: Integrates memory management, VME interface, and timing functions into a single chip, significantly enhancing memory subsystem performance and reducing latency.
- High-Performance DMA: Supports Direct Memory Access for VMEbus D64 block transfers and local bus memory burst cycles, offloading data transfers from the CPU.
- Integrated Network & Storage: Features onboard 10/100Mbps Ethernet and SCSI interfaces, both utilizing DMA for high-speed throughput.
- Serial Communications: Provides four asynchronous serial ports (EIA-232-D DTE) routed to RJ45 connectors.
- IndustryPack Expansion: Accommodates up to two IndustryPack (IP) modules via a 32-bit data path, with dedicated DMA channels for each IP slot.
- System Timers: Includes six 32-bit tick timers and a hardware watchdog timer to prevent system lockups.
Application Scenarios
Extensively utilized in semiconductor manufacturing tools, advanced motion control systems, radar signal processing, aerospace ground systems, automated test equipment (ATE), and distributed industrial control systems.
Performance Parameters
- Power Requirements: +5Vdc (±5%) at 3.5A typical and 4.5A maximum; +12Vdc and -12Vdc at 100mA maximum each.
- Thermal Specifications: Operating temperature ranges from 0°C to 70°C exit air with forced-air cooling. Storage temperature ranges from -40°C to +85°C.
- Environmental Tolerance: Operates reliably in 5% to 90% relative humidity (non-condensing).
- Interrupt Handling: Supports a 7-level VMEbus interrupter and interrupt handler for real-time event processing.
