The VME162PA-344SE-2G is a high-performance embedded Single Board Computer (SBC) based on the VMEbus architecture. It is mainly targeted at critical embedded system applications such as industrial control, aerospace, and national defense, which have strict requirements for reliability, stability, and expandability.
As a custom-configured product in the VME series boards, its core positioning is to provide a hardware platform with high computing power processing, large-capacity storage, and rich expansion interfaces for complex embedded scenarios, while featuring industrial-grade environmental adaptability and long-term stable operation capability.
Core Configuration and Features
1. Processor and Core Performance
Core Processor: It is presumed to be equipped with a high-performance PowerPC architecture processor (combined with the characteristics of the product series, it is most likely a PowerPC 750 or a 32-bit microprocessor of the same class). It has high instruction execution efficiency and can meet the needs of complex data operations and real-time control.
Cache Configuration: Equipped with 32KB/32KB Level 1 Cache (L1 Cache, separate instruction and data caches), and may integrate a 1MB-level Level 2 Cache (L2 Cache). This significantly reduces the data latency between the processor and memory, and improves the overall computing performance.
2. Memory and Storage Configuration
Main Memory: Supports 32MB to 512MB SDRAM with ECC (Error Checking and Correction) function. It can effectively detect and repair memory data errors, avoid system failures caused by memory anomalies, and ensure the stable operation of critical tasks.
Storage Expansion: On-board multi-specification Flash storage, including 1MB-level Flash for firmware storage and 8MB-level Flash for user data. Meanwhile, it integrates 8KB NVRAM (with real-time clock and replaceable backup battery), meeting the needs of firmware solidification, persistent storage of user data, and system time synchronization.
3. Expansion and Peripheral Interfaces
VMEbus: Fully compliant with the VME64 standard (ANSI/VITA 1-1994), supporting 32/64-bit address and data transmission. It has 4-level requester, 7-level interrupter, and 7-level interrupt handler capabilities, enabling seamless access to VMEbus systems and realizing multi-device collaborative work.
PMC Expansion: Equipped with 2 32/64-bit PMC expansion slots, supporting single-width/double-width PMC modules. It can flexibly expand functions such as communication (e.g., optical fiber, serial port), data acquisition, and image processing, adapting to diverse application scenarios.
PCI Expansion: Provides a 64-bit PCI expansion mezzanine connector, further expanding the connection capability between the board and external devices, and compatible with more standard PCI peripherals.
Basic Peripherals: Integrates a 10/100Mb/s Ethernet interface (meeting network communication needs), an asynchronous serial debug port (facilitating system debugging and maintenance), 4 32-bit timers, 1 16-bit timer, and 1 watchdog timer (ensuring system timing control and abnormal reset).
4. Reliability and Environmental Adaptability
Industrial-Grade Design: Adopts industrial-grade components and reinforced layout, supporting a wide operating temperature range of 0°C to +55°C. It has vibration resistance and shock resistance capabilities, and can adapt to harsh operating conditions such as industrial sites, vehicle-mounted, and airborne environments.
High Stability: Has passed long-term aging tests and environmental stress tests, with a Mean Time Between Failures (MTBF) reaching the level of hundreds of thousands of hours, complying with the strict reliability requirements of key fields such as national defense and aerospace for equipment.
