1 Introduction
The phyCORE-P8xC51Mx2 belongs to PHYTEC’s phyCORE Single
Board Computer (SBC) 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
Electro Magnetic Interference (EMI) 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 modules achieve their small size through advanced 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.
