Preface
Preface
This phyCORE-TC1796 Hardware Manual describes the board's
design and functions. Precise specifications for Infineon’s TC1796
TriCore microcontroller series controller can be found in the enclosed
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 of Electro Magnetic Conformance of the
PHYTEC phyCORE-TC1796
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 Conformance 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-TC1796 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 all
common 8- and 16-bit as well as selected 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 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.

1Introduction
The phyCORE-TC1796 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-TC1796 is a subminiature (71,5 x 57) insert-ready
Single Board Computer populated with Infineon’s TC1796 Tricore
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 Data Sheet. The
descriptions in this manual are based on the Infineon TC1796 Tricore
microcontroller. No description of compatible microcontroller
derivative functions is included, as such functions are not relevant for
the basic functioning of the phyCORE-TC1796.
