Manufacturer: Aitech

The C108 is a member of Aitech’s renowned C10x VME SBC family. It is designed for harsh environment applications that require high performance, low power, and multiple I/O capabilities.

This powerful single-board computer combines an enhanced processing engine with versatile and flexible I/O. Powered by Freescale’s advanced PowerPC® MPC7448 microprocessor at 1.4 GHz with integrated on-chip L1 and L2 caches, the C108 provides excellent processing capability while consuming minimum power and generating a low level of heat. For even lower power consumption and heat generation, the C108L and C108U configurations are also available, with processors operating at 1.066 GHz and 600MHz respectively.

The large, fast SDRAM array is supplemented by additional memory arrays, such as Flash for user application storage, high-density NAND Flash for mass storage purposes, USB Solid State Disk (SSD), and NVRAM for user/application-specific parameter storage.

In addition to its high-performance processor architecture, the C108 provides unparalleled I/O capabilities, all integrated on board. I/O interfaces include a Gigabit Ethernet port, two Fast Ethernet ports, two dual-redundant MIL-STD-1553B interfaces, an opto-isolated CANBus 2.0B interface, two USB 2.0 ports, eight serial ports (six high-speed ports and two standard UART ports), and 16 single-ended TTL or 8 differential RS-422 discrete I/O channels. The C108 enables further enhancement of all this functionality by providing two PMC expansion slots. 

The C108 internal architecture is based on two separate 64-bit wide PCI buses, one operating at 66/33 MHz and the other at 33 MHz, enabling separation of the slow PCI devices from the faster ones so that each PCI device can operate at its top speed. In order to achieve maximum bus utilization, multiple advanced programmable DMA engines are available for data transfer over the PCI buses.

The C108 implements a VME64x compliant interface using Tundra’s Universe II PCI to VME Bridge.
