The CM-i586 is designed to serve as a building block in embedded application design. The CMi586 module has all the components needed to run operating systems such as DOS, Linux, VxWorks or Windows CE. Its 'credit card' size allows integration into hand-held and mobile applications, providing a powerful computer core. The feature set of the CM-i586 module combines a Pentium-class CPU, PC/AT system logic and essential computing peripherals. For embedded applications, the CM-i586 provides a 32-bit PCI bus, 100Mbit Ethernet, 16C550-compatible UART's, 32 I/O lines and many other essential functions.
