Preface
This phyCORE-SC520 Hardware Manual describes the board’s design
and functions. Precise specifications for the “Elan SC520” controller
series can be found in the enclosed microcontroller Data Sheet/User's
Manual from AMD as well as the documentation for peripheral
components: “FDC37B787, Enhanced Super I/O Controller with
ACPI Support, Real-Time Clock and Consumer IR” from SMSC and
“RTL8139C, Single Chip Fast Ethernet Controller with Power
Management” from Realtek. If software is included also refer to
additional documentation for this software.
In this hardware manual and in the attached schematics, low active
signals are denoted by a "/" in front of the signal name (i.e.: /RD). A
"0" indicates a logic-zero or low-level signal, while a "1" represents a
logic-one or high-level signal.
Declaration of Electro Magnetic Conformance of the
PHYTEC phyCORE-SC520
PHYTEC Single Board Computers (henceforth “products”) are
designed for installation in electrical appliances or as dedicated
Evaluation Boards (i.e.: for use as a test and prototype platform for
hardware/software development) in laboratory environments.
Caution:
PHYTEC products lacking protective enclosures are subject to
damage by ESD and, hence, may only be unpacked, handled or
operated in environments in which sufficient precautionary measures
have been taken in respect to ESD-dangers. It is also necessary that
only appropriately trained personnel (such as electricians, technicians
and engineers) handle and/or operate these products. Moreover,
PHYTEC products should not be operated without protection circuitry
if connections to the product's pin header rows are longer than 3 m.

phyCORE-SC520
2PHYTEC Meßtechnik GmbH 2002 L-554e_2
Implementation of PHYTEC products into target devices, as well as
user modifications and extensions of PHYTEC products, are subject
to renewed establishment of conformity to, and certification of,
Electro Magnetic Directives. Users should ensure conformance
following any modifications to the products as well as implementation
of the products into target systems.
The phyCORE-SC520 is one of a series of PHYTEC Single Board
Computers that can be populated with different controllers and,
hence, offers various functions and configurations.
PHYTEC supports all common 8- and 16-bit as well as specific 32-bit
controllers in two ways:
(1) as the basis for Rapid Development Kits which serve as a
reference and evaluation platform
(2) as insert-ready, fully functional micro-, mini- and phyCORE
OEM modules, which can be embedded directly into the user’s
peripheral hardware, design.
PHYTEC's microcontroller modules allow engineers to shorten
development horizons, reduce design costs and speed project concepts
from design to market.

Introduction

1Introduction
The phyCORE-SC520 belongs to PHYTEC’s phyCORE Single Board
Computer module family. The phyCORE SBCs represent the
continuous development of PHYTEC Single Board Computer
technology. Like its mini-, micro- and nanoMODUL predecessors, the
phyCORE boards integrate all core elements of a microcontroller
system on a subminiature board and are designed in a manner that
ensures their easy expansion and embedding in peripheral hardware
developments.
As independent research indicates that approximately 70 % of all EMI
(Electro Magnetic Interference) problems stem from insufficient
supply voltage grounding of electronic components in high frequency
environments, the phyCORE board design features an increased pin
package. The increased pin package allows dedication of
approximately 20 % of all pin header connectors on the phyCORE
boards to Ground. This improves EMI and EMC characteristics and
makes it easier to design complex applications meeting EMI and
EMC guidelines using phyCORE boards even in high noise
environments.
phyCORE boards achieve their small size through modern SMD
technology and multi-layer design. In accordance with the complexity
of the module, 0402-packaged SMD components and laser-drilled
Microvias are used on the boards, providing phyCORE users with
access to this cutting edge miniaturization technology for integration
into their own design.
We at PHYTEC consider it our responsibility, as a reliable partner
and ISO 9001 certified supplier, to enable the integration of our insert
ready microcontroller modules into your OEM production. This is an
important condition for the success of our product.

phyCORE-SC520

The phyCORE-SC520 is a subminiature (60 x 53 mm) insert-ready
Single Board Computer populated with the Elan SC520 micro-
controller from AMD.
Its universal design enables its insertion in a wide range of embedded
applications. All controller signals and ports extend from the
controller to high-density pitch (0.635 mm) connectors aligning two
sides of the board, allowing it to be plugged like a “big chip” into a
target application.
Precise specifications for the controller populating the board can be
found in the applicable controller User’s Manual or Data Sheet. No
description of compatible microcontroller derivative functions is
included, as such functions are not relevant for the basic functioning
of the phyCORE-SC520.
