Description
Motorola MVME162P-242
Technical Specifications
- Processor: 25 MHz MC68LC040 (8KB cache, MMU, no FPU).
- Memory: 16MB SDRAM with parity protection.
- Storage: 512KB battery-backed SRAM, 1MB Flash, 8K NVRAM.
- Interfaces: Dual serial ports, four IndustryPack ports.
Functional Features
- Petra ASIC Integration: Replaces older MC2/IP2/MCECC chips for improved memory subsystem performance.
- VMEbus Support: A32/D64 master/slave with system controller.
- DMA: High-performance DMA for VME D64 and local bus bursts.
- Serial Communication: Console (EIA-232-D DCE) and configurable user port (EIA-232-D/EIA-422).
Application Scenarios
General industrial automation, PLC core processing, data acquisition, and OEM embedded monitoring.
Performance Parameters
- Expansion: Four 16-bit or two 32-bit IP ports with DMA.
- Timers: Six 32-bit timers, one watchdog.
- Power: +5Vdc ±5%, 1.75A typical, 2.25A max; +12V/-12V 100mA max.
Material Composition
Multi-layer industrial PCB with MC68LC040, SDRAM, and Petra ASIC.
Structural Characteristics
Standard 6U VME size (233mm x 160mm) with P1/P2 connectors and front-panel LEDs/switches.
Working Principle
MC68LC040 communicates with Petra ASIC via local bus. ASIC manages SDRAM, SRAM, Flash, VME interface, and handles DMA transfers.
Installation Requirements
- Insert into compatible 6U VME chassis.
- Configure memory size and boot mode via hardware switches.
- Ensure forced-air cooling (-5°C to 55°C operating range).
Usage Precautions
- No hot-swapping.
- Check SRAM/NVRAM battery voltage regularly.
- Use ESD protection during handling.
