D.1b General Description
The SAT-520Plus is a highly integrated PC/104 and PC/104Plus expandable
module with x86 compatibility and standard PC-AT architecture. It utilizes
the latest of AMD’s embedded processors, the ELAN SC520. The SC520
incorporates a 5x86 CPU core running at 133MHz along with a full 33MHz
PCI host bridge, internal AT style peripherals, dual serial ports, and an IDE
interface. The addition of the SMSC 37B727 adds the keyboard/mouse
controller, two more plug-n-play serial ports, and a SPP/EPP/ECP parallel
printer port, dual floppy disk interface. 24 lines of digital I/O, VGA and flat
panel support also adds to the expansive feature set. Also onboard the
SAT-520Plus is the popular Intel 82551ER10/100 Ethernet controller making
this board an excellent choice for embedded applications requiring
integrated networking. The 133MHz 5x86 CPU core and the integrated
floating point processor offer an excellent compromise between computing
power and power consumption. Feature expansion is also supported via
either the popular PC/104 expansion bus or through the newer
high-performance PCI type PC/104Plus expansion bus. The SAT-520Plus
supports both standard rotational media drives, floppy and hard disk, or the
popular DiskOnChip® flash modules in sizes ranging from 8 to 288 Mbytes.
