1 Introduction
The phyCORE-MCF548x 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-MCF548x is a subminiature (70 x 57 mm) insert-ready
Single Board Computer populated with Freescale’s ColdFire
MCF548X 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.
