Because of its small size DMA controller, and interrupt controllers. It is based upon and low power consumption, it is well suited for portable and 0.25-micron process technology that allows for its low mobile products. power consumption in a small BGA package. It is powered by an AMD SC520 operating at 133MHz. The AMD SC520 runs the industry-standard x86 micro- A 10/100 Ethernet controller provides high-speed Ethernet processor instruction set. Its software compatibility access in addition to four serial COM ports. Up to 256MB supports the use of Windows® CE, Linux and DOS of memory can be installed in a SODIMM socket. Also, operating systems, x86-compatible real-time executives, a CompactFlash can be installed for on board solid state development tools, and applications programs. This flash storage. improves time-to-market and allows easy software migra- tion to the board.

DOCs are available in commercial and industrial tem- perature ranges. A CompactFlash connector will accept Type I and II CompactFlash cards. It is wired to the primary IDE chan- nel. A designer can use bootable CompactFlash cards as data storage for applications where the environment is too harsh for rotational hard disks or floppy disk drives. WinSystems offers industrial-grade CompactFlash cards that can be used to boot and store data like a solid state disk drive while operating from -40° to +85°C for high capacity, harsh embedded applications. The sustained data transfer rate is very fast, plus an on-card wear leveling algorithm extends the number of write cycles to the part. These RoHS-compliant cards will fit into any computer, SBC, or instrument with a CompactFlash socket.
