Aitech C105 - Rugged/Mil PowerPC® VME SBC

Up to 1 GB (ECC) SDRAM, 2 PMC Slots, 2x 10/100 LAN


As a member of Aitech’s renowned C10x VME SBC family, the C105 is designed for harsh environment applications that require high performance, low power, and multiple I/O capabilities.

The C105 is a pin compatible drop-in replacement for Aitech's ruggedized C5100 and C5110 SBCs. As a 100% Aitech designed and manufactured product, continued long term availability of the C105 is assured by Aitech, independently of C5100/C5110 availability.

This powerful single-board computer combines an enhanced processing engine with versatile and flexible I/O. Powered by Freescale’s advanced PowerPC G4+ MPC7448 microprocessor at 1 GHz with integrated on-chip L1 and L2 caches, the C105 provides excellent processing capability while consuming minimum power and generating minimum heat.

The large, fast SDRAM array is supplemented by additional memory arrays, such as Flash for user application storage, high-density Flash File for mass storage purposes, and NVRAM for user/application specific parameter storage.

In addition to its high performance processor architecture, the C105 provides two fast Ethernet ports and six serial ports. Two industry standard PMC slots enable addition of functionality.

C105 internal architecture is based on two separate 64-bit wide PCI buses, one operating at 66/33 MHz and the other at 33 MHz. This enables separation of slow PCI devices from 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 C105 implements a VME64x compliant interface using Tundra’s Universe II PCI to VME Bridge.
