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.

Introduction

1Introduction
The Carrier Board phyCORE-PXA270 is a universal carrier board for
start-up and programming of the PHYTEC
phyCORE-PXA270 Single Board Computer module with two high
density SMT (160 pins each, 0.63 mm pitch) pin header connectors.
The Carrier Board is fully equipped with all mechanical and electrical
components necessary for the speedy and secure insertion and
subsequent programming of the high-density PHYTEC phyCORE
module. These components include TFT display connection, touch
screen interface, Ethernet transformer and connector, DB-9, USB and
power socket connectors.
The phyCORE module can be plugged like a "big chip" onto the
Carrier Board's mating Molex connectors. Once programmed, the
phyCORE module can be removed from the Carrier Board and
inserted like a "big chip" in a target hardware application. Given the
compact nature of the Carrier Board use of the complete hardware
platform as OEM part in human-machine-interface (HMI) applications
is also possible.
The hardware manual for this Carrier Board does not describe the
features and functions of the phyCORE-PXA270 SBC module, as this
is not relevant for the basic functioning of the Carrier Board. For
module and controller-specific features please refer to the
corresponding Hardware Manuals/User’s Manuals.

The Carrier Board offers the following features:
•Molex connectors for mating with phyCORE-PXA270 SBC
module
•Connector for 8.4" Sharp TFT display with 640*480 pixel
resolution, incl. adjustable inverter for background illumination
•AC97 controller WM9712L with touch and sound interface (Line-
IN, Line-OUT, MIC-IN and 0.4 watts speaker)
•Two DB-9 sockets for RS-232 interface from FF-UART and
BT-UART, 2*5 pin header for IR-UART
•One DB-9 plug for CAN interface, optical isolation
•RJ-45 Ethernet connector with transformer for 100/10 MBit/s
•USB host socket for PXA270 USB host interface
•USB client socket for PXA270 USB client interface
•Power supply for unregulated input voltage from 12 V (optional
24 V). It supplies regulated +3.3 V for the
phyCORE-PXA270. Additional +5 V is created for the IDE and CF
card and LCD/inverter circuitry.
•Optional battery charger circuitry for NiMH batteries
•Power magement for MMC, CF, IDE and LC display
•Two user programmable LEDs
•Optional IDE interface for two 2.5" hard disks (Master / Slave)
•Interface for matrix keyboards
•JTAG interface

2Port Pin Initialization
The Intel PXA270 controller provides a wide variety of chip-level
features that are routed to GPIO pins with alternative functions. The
following functions are used on the phyCORE-PXA270 Carrier
Board:
•MMC Card 0/1
•PCMCIA interface
•16-bit LCD interface
•AC97 interface
•FF-UART, BT-UART and IR-UART
•SSP and NSSP
•I²C bus
•USB client and host
Either the operating system installed on the phyCORE-PXA270 or the
boot loader (e.g. U-Boot) must initialize the GPIO port pins in
questions as shown in the table below:
