SAT-520Plus Technical Reference
The SAT-520Plus uses the latest AMD embedded processor/chipset solution, the Elan
SC520. The SC520 contains the following subsystems:
ƒ
133MHx Am5X86 CPU core with floating point unite and a 16KB write-back cache
ƒ
Integrated PCI 2.2 compliant host bridge running at 33MHz
ƒ
SDRAM Controller
ƒ
ROM/Flash Controller
ƒ
Programmable Interval Timers
ƒ
Real Time clock/CMOS RAM
ƒ
Programmable Interrupt Controllers
ƒ
Programmable DMA Controllers
ƒ
Dual 16550 Compatible Serial Ports
ƒ
Dual IDE Chip Selects
ƒ
PS/2 Style Gate A20 and reset functions
The SAT-520Plus augments the inherent feature set of the AMD SC520 by adding the
SMSC 37C727 PnP Super I/O chip. This chip contains these subsystems.
ƒ
Dual Floppy disk interface
ƒ
PS/2Mouse controller
ƒ
PS/2 Keyboard controller
ƒ
Two 16550 compatible serial ports
ƒ
SPP/EPP/ECP compatible parallel printer port
The SAT-520Plus included a fourth generation CRT/Flat panel controller that supports
standard VGA output as well as a variety of Flat Panel Displays.
The SAT-520Plus also includes an 82C55A-type device supporting 24 lines of digital
I/O.
The SAT-520Plus also utilizes the Intel 82551ER10/100 Ethernet Controller for
compatibility with a variety of network operating systems and software.
Support for the M-Systems DiskOnChip
®
device is present which allows for Flash
drives in sizes from 8 to 288 MB.
AMD Elan SC520 Processor
– The AMD SC520 is the latest in AMD’s line of
embedded processors. The SC520 incorporates the CPU, FPU, DRAM controller,
Flash/ROM controller, PCI controller, RTC/CMOS RAM, and Chip selections for DOC
support and the IDE interface.
The processor is supplied from AMD in a 388-pin PBGA package and is soldered
directly to the board at the factory. This part is not user replaceable of upgradeable.
The core CPU runs at a base clock frequency of 33MHz. An internal software controlled
multiplier of either 3X of 4X results in internal processor speeds of either 100MHz or
133MHz. The multiplier selection is user definable using the
Phoenix BIOS Setup
utility.
