NOTICE
Advanced Micro Devices, Inc. ("AMD") has purchased the Information Appliance business unit of National Semiconductor Corporation ("National"), which consisted
primarily of the GeodeTM family of microprocessor products and related support products (GX1, GX2, CS5530A, CS5535, CS1301, CS1311, SC1100, SC1200,
SC1201, SC2100, SC2200, SC3200, XpressROMTM and XpressLoaderTM software, collectively, the "IA Products"). This business unit is now being operated by
AMD's PCS Division.
During a transitional period, AMD will continue to use and distribute IA Product technical and marketing documents originally produced by National in hard copy, pdf,
html or other electronic format.
Notwithstanding the appearance in this document of the National trade names, National trademarks, and National copyrights or other proprietary notices, AMD is the
seller of the IA Products described in this document, the owner of the content contained in this document, and the source/publisher of this document.

1) This design features the SC3200 in the TEPBGA package. Please read the SC3200 P17 AUDIO
Data sheet, and Errata document for the particular revision of silicon to be P18 SMART CARD

used. Certain parts of this schematic may need to be changed to accommodate FLOPPY PORTS
P20 CRT
work-arounds for issues with a particular silicon revision. P21 VIP
2) PCB Layout notes are included with this schematic in various places. However, P22 SYSTEM POWER
use the SC3200 Layout Guidelines for proper PCB layout.

3) No board has been built from this schematic.
4) Not all sections of this design may be appropriate for a particular
application.
5) It is not recommended that both CompactFlash and IDE be used in the same
design. CompactFlash, Dual IDE ports, and a Single IDE port are shown on separate
sheets. The designer should choose one of the three sheets to use in a design.
6) It is not recommended that both a standard PCI slot and a Mini-PCI slot be
used in the same design. These are shown on separate sheets. The designer should
choose one or the other sheets to use in a design.
7) Please read the "Important Notice" below.
8) Be sure to check the IA Developers Web Site often to get updated schematics or
a schematic errata document.

9) The pin properties on part symbols may need to be changed to support a B




particular application.
