The
CM-X270 is a small Computer-on-Module board designed to serve as a building
block in embedded applications. The CM-X270 has all the components
required to run operating systems such as Linux and Windows CE. Ready packages for
these operating systems are available from
CompuLab. The small size and low
power consumption of the
CM-X270
allows its integration into hand-held and mobile
applications, while its low
price makes it an ideal selection for cost-sensitive
applications. Based on Intel's XScale architecture, the CM-X270 delivers a
price/performance ratio significantly better than that of any other platform.
The feature set of the CM-X270 module combines a
32-bit CPU, SDRAM, Flash Disk and vital computing peripherals. For embedded
applications, the CM-X270 provides a 32-bit PCI bus, 100Mbit Ethernet,
serial ports, general purpose I/O lines and many
other essential functions.
An integrated WLAN (WiFi) interface
implements 802.11b/g industry standard wireless connectivity.
The standardized CAMI ("CompuLab's
Aggregated Module Interface") connectors of the CM-X270 module allow
interchangeability with
other Computer-On-Module's available from CompuLab, enabling the flexibility required in
a dynamic market where application requirements
can change rapidly.
