Preface
Preface
This manual describes only the functions of the PHYTEC
phyCORE-PXA270 Carrier Board. The controllers and relevant Single
Board Computers for use with the Carrier Board are not described
herein. Additional controller- and board-level information and
technical descriptions can be found in appropriate Hardware Manual
or User's Manual support documentation. If software is included
please 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 regarding Electro Magnetic Conformity
of the phyCORE-PXA270 Carrier Board
PHYTEC Carrier Boards (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.
Note:
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.

Carrier Board phyCORE-PXA270

PHYTEC products fulfill the norms of the European Union's Directive
for Electro Magnetic Conformity only in accordance to the
descriptions and rules of usage indicated in this hardware manual
(particularly in respect to the pin header rows or connectors, power
connector and serial interface to a host-PC).
Implementation of PHYTEC products into target devices, as well as
user modifications and extensions of PHYTEC products, is 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-PXA270 Carrier Board is one of a series of PHYTEC
Carrier Boards supporting the phyCORE-PXA270 Single Board
Computer module. PHYTEC supports common 8-, 16- and selected
32-bit controllers on two types of Single Boards Computers:
(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.
