CM-iVCF Computer-On-Module

Mature product, not for new designs. Discontinued features are colored in gray.

 

Description

The CM-iVCF module is a small but extremely powerful PC-compatible CoM (Computer-on-Module), designed to serve as a building block in a variety of embedded applications. The CM-iVCF has all the components needed to run operating systems such as Windows  XP, Windows CE or Linux. Ready BIOS and operating systems packages are available from CompuLab.

The CM-iVCF is both small and inexpensive relative to products of its class, which allows its integration into compact applications requiring both embedded and multimedia feature sets.

The feature set of the CM-iVCF module includes practically all of the components found in a high-end desktop computer. For embedded applications, the CM-iVCF provides a Flash Disk, PCI bus, 100Mbit Ethernet, UART’s, I/O lines and many other essential functions. For multimedia applications, the CM-iVCF has a dual head graphics controller, an MPEG decoder, sound and touchscreen controllers.

Software support for the CM-iVCF includes ready-to-run packages for:

* Linux
* Windows CE & XP
* DOS
