1.1 Introduction
The phyCORE-i.MX35 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.MX35 is a subminiature (85 x 58 mm) insert-ready Single Board Computer populated
with the Freescale i.MX35x 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.MX35x. No
description of compatible microcontroller derivative functions is included, as such functions are not
relevant for the basic functioning of the phyCORE-i.MX35.
