GE V7768 VME Single Board Computer

Core positioning and advantages of the product

V7768 is a VME bus single board computer based on Intel architecture, featuring high flexibility and rich I/O expansion capabilities, suitable for industrial scenarios that require stable embedded computing. Its core advantages include:

Supports Intel Core 2 Duo/Celeron M processors, adapting to different performance and temperature requirements;

Integrate multiple types of interfaces (dual Gigabit Ethernet, SATA, USB, etc.) to meet basic connectivity requirements without the need for additional expansion;

Provide PCI-X PMC expansion slots and board to board connectors, which can further expand up to 3 PMC sites and adapt to complex I/O scenarios;

Compatible with mainstream operating systems such as Windows XP, VxWorks, Linux, and adaptable to various software environments.

Hardware configuration and performance parameters

1. Processor and Storage

Category specific configuration

Processor - Intel Core 2 Duo: up to 2.16GHz, 4MB L2 cache, 667MHz system/memory bus

-Intel Celeron M: 1.07GHz, 1MB L2 cache, 533MHz system/memory bus

Maximum 2GB DDR2 SDRAM memory (expandable through a single SODIMM slot)

Storage expansion supports up to 8GB CompactFlash (accessible through a secondary IDE port and configurable as a BIOS boot device)

Non volatile storage 32KB non-volatile SRAM (used to store critical data)

2. Interface and Expansion Capability

The V7768 interface covers scenarios such as network, storage, peripherals, and bus expansion, as follows:

Network interface: Dual Gigabit Ethernet (based on Intel 82571 chip), both connected through RJ45 connectors on the front panel, supporting PCIe network boot;

Storage interface: 2 SATA interfaces (leading to the rear P2 interface), used for connecting hard drives/SSDs;

USB interface: 4 USB 2.0 ports (2 front panel, 2 rear P2 ports), supporting synchronous data transfer, automatic peripheral recognition, and hot plugging;

Serial interface: 2 16550 compatible serial ports (DB-9 connector), COM1 front, COM2 rear, supporting up to 115K baud rate, including 16 byte FIFO;

Human computer interaction interface: The front panel integrates PS/2 keyboard/mouse interface and SVGA display interface;

Bus and Expansion:

VME bus: supports VME64 mode (A32/A24/D32/D08 (EO)/MBLT64/BLT32), including hardware byte swapping and enhanced bus error handling;

PMC Expansion: 1 133MHz PCI-X PMC slot, supporting VITA35 standard; By pairing the board to board connector with the PMC237CM1/V expansion board, an additional 3 32-bit/33MHz PMC stations can be added.

3. Timer and monitoring function

Programmable timers: 2 16 bit timers+2 32-bit timers, mapped to PCI memory space, supporting software programming and PCI bus interrupts;

Watchdog timer: configurable time interval, supports interrupt triggering and board level reset, improves system stability;

BIOS: The system BIOS and video BIOS are stored in programmable flash memory and support device configuration during startup.
