1Preface

This hardware manual describes the phyCORE-i.MX27 Single Board Computer’s design and function.

Precise specifications for the Freescale i.MX27 microcontrollers can be found in the enclosed

microcontroller Data Sheet/User's Manual.

In this hardware manual and in the attached schematics, active low signals are denoted by a "/" or “#”

preceding the signal name (e.g.: /RD or #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 Conformity of the PHYTEC

phyCORE-I.MX27

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.

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 row 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-i.MX27 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 a

variety of 8-/16- and 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 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. For more information go to:

1.1 Introduction

The phyCORE-i.MX27 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.

The phyCORE-i.MX27 is a subminiature (84 x 60 mm) insert-ready Single Board Computer populated

with the Freescale i.MX27 microcontroller. 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 datasheet. The descriptions in this manual are based on the Freescale i.MX27. No

description of compatible microcontroller derivative functions is included, as such functions are not

relevant for the basic functioning of the phyCORE-i.MX27.
