Preface
1 Preface
This hardware manual describes the phyCORE-i.MX31 Single Board Computer’s design and function.
Precise specifications for the Freescale i.MX31 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.

phyCORE-I.MX31
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.MX31 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:
