Preface
This phyCORE-MPC5200B tiny Hardware Manual describes the
board’s design and functions. Precise specifications for the Freescale
MPC5200B microcontroller series can be found in the enclosed
MPC5200B microcontroller Data Sheet/User's Manual. 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 PHYTEC phyCORE-MPC5200B tiny
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.
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.

phyCORE-MPC5200B tiny
2PHYTEC Messtechnik GmbH 2006 L-678e_0
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-MPC5200B tiny 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
common 8-, 16- and numerous 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 phyCORE OEM modules, which
can be embedded directly into the user’s target design.
PHYTEC's microcontroller modules allow engineers to shorten
development horizons, reduce design costs and speed project concepts
from design to market.

Introduction
PHYTEC Messtechnik GmbH 2006 L-678e_0 3
1Introduction
The phyCORE-MPC5200B tiny 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 sub-miniature 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 and laser-drilled Microvias
components are used on the boards, providing phyCORE users with
access to this cutting edge miniaturization technology for integration
into their own design.
The phyCORE-MPC5200B tiny is a subminiature (53 x 57 mm)
insert-ready Single Board Computer populated with Freescale’s
PowerPC MPC5200B 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
(0.635 mm) Molex pin header connectors aligning two sides of the
board, allowing it to be plugged like a "big chip" into a target
application.

1.3 Minimum Requirements to Operate the
phyCORE-MPC5200B tiny
Basic operation of the phyCORE-MPC5200B tiny only requires
supply of a +3V3 input voltage and the corresponding GND
connection.
These supply pins are located at the phyCORE-connector X1:
+3V3 X1 1C, 2C, 4C, 5C, 1D, 2D
GND X1 3C, 3D, 7C, 9D, 12C, 14D
Caution:
We recommend connecting all available +3V3 input pins to the power
supply system on a custom carrier board housing the
phyCORE-MPC5200B tiny and at least the matching number of GND
pins neighboring the +3 V3 pins.
In addition, proper implementation of the phyCORE module into a
target application also requires connecting all GND pins neighboring
signals that are being used in the application circuitry.
Please refer to section 4 for more information.

Pin Description
PHYTEC Messtechnik GmbH 2006 L-678e_0 9
2Pin Description
Please note that all module connections are not to exceed their
expressed maximum voltage or current. Maximum signal input values
are indicated in the corresponding controller manuals/data sheets. As
damage from improper connections varies according to use and
application, it is the user's responsibility to take appropriate safety
measures to ensure that the module connections are protected from
overloading through connected peripherals.
Many of the phyCORE-MPC5200B tiny pins offer alternative
functions. These alternative functions must be activated by
configuring the applicable controller registers prior to their use.
Certain controller functions are pre-configured based on the module’s
design and are shown in Table 1. Signals that are routed directly from
the CPU to the Molex connectors can configured to any available
alternative function desired by the user. In contrast, signals that are
used on the phyCORE-MPC5200 tiny as listed in Table 1 can only be
used if a special module configuration was purchased (e.g. SBC
version without on-board RS-232 transceivers. Please contact
PHYTEC for more details.
Note:
The following sections of this manual assume use of the port pins
according to configuration listed in Table 1.

As Figure 3 indicates, all controller signals extend to surface mount
technology (SMT) connectors (0.635 mm) lining two sides of the
module (referred to as phyCORE-connector; refer to section 2). This
allows the phyCORE-MPC5200B tiny to be plugged into any target
application like a "big chip".

J1850_TX signal, if the PHY is not populated
or in "isolation mode".
The pin state is latched by the CPU after reset
and used as "byte lane swap" configuration.
Refer to section 5, "System Start-Up
Configuration". There is a 10kOhm pull-
down resistor on this signal..
