The XYCOM XVME-655 is a VMEbus Pentium processor module designed for industrial automation and control applications. Here are the detailed specifications:
- Manufacturer: XYCOM
- Type: VMEbus Processor Module
- VMEbus Compliance: Complies with VMEbus Specification, IEEE 1014–1987 Rev. C.1
- Form Factor: Double - height, double - width, 233.35 mm x 160 mm (9.2" x 6.3")
- Weight: Approximately 0.72 kg
- Country of Origin: USA
- CPU: Intel Pentium processor
- CPU Speed Options: 75 MHz, 100 MHz, 133 MHz, 166 MHz, 200 MHz, 200 MHz MMX, 233 MHz MMX
- L2 Cache: 512 Kbyte synchronous pipeline Level 2 cache (COAST) on 133, 166, 200, or 233 MHz CPU configurations
- DRAM: The amount of DRAM is not clearly specified in all sources, but it is likely to be configurable. Some references mention 64 MB DDR SDRAM, while others may imply larger capacities based on the system's expandability.
- Flash Memory: The size of flash memory is not uniformly documented. It could be 128 MB Flash ROM according to some sources, or other values such as 16 MB Flash in different configurations.
- Serial Ports: 2 x 16550 - compatible serial ports
- Parallel Interface: 1 x EPP/ECP - compatible parallel port
- Ethernet: Optional 10 Mbit or 100 Mbit Ethernet interface
- IDE Interface: Enhanced IDE controller supporting programmed I/O (PIO) and bus mastering DMA with transfer rates up to 22 Mbytes/second. It can support up to two IDE devices. The IDE hard drive and floppy drive signals are routed through the P2 connector, and the module supports only one floppy drive.
- Video Interface: PCI Super VGA Graphics Controller, supporting resolutions up to 1024 x 768 with 256 colors and hardware - assisted video playback for Indeo and MPEG - 1.
- Power Supply: Requires +12V, -12V, and +5V power supplies
- Power Consumption: Not precisely documented in all available sources, but typical Pentium - based VME modules of this era have moderate power consumption depending on the CPU speed.
- VMEbus Integration: The PCI to VMEbus interface allows for seamless integration into VME - based systems. The interface contains four master and four slave images that can be programmed in a variety of modes to allow the VMEbus to be mapped into the XVME - 655 local memory.
- Flash Update Feature: An on - board switch controls which part of the Flash device is loaded into shadow DRAM, allowing for half of the Flash device to be updated while still retaining a copy of the original content.
- Industrial Automation: Used for complex control systems in manufacturing plants, where it can handle real - time control tasks, data processing, and communication with other industrial devices.
- Test and Measurement: Suitable for use in test equipment, where its processing power and various interfaces can be used to control measurement processes and analyze data.
- Aerospace and Defense: Can be applied in some aerospace and defense - related systems that require reliable and high - performance computing within a VMEbus - based architecture.
