1 Introduction
The phyCARD-M belongs to PHYTEC’s phyCARD Single Board
Computer module family. The phyCARD
SBCs represent the
continuous development of PHYTEC Single Board Computer
technology. Like its mini-, micro- and nanoMODUL predecessors, the
phyCARD 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.
PHYTEC's phyCARD family introduces the newly developed X-Arc
embedded bus standard. Apart from processor performance, a large
number of embedded solutions require a corresponding number of
standard interfaces. Among these process interfaces are for example
Ethernet, USB, UART, SPI, I
2
C, audio, display and camera
connectivity. The X-Arc bus exactly meets this requirement. As well
the location of the commonly used interfaces as the mechanical
specifications are clearly defined. All interface signals of PHYTEC's
new X-Arc bus are available on a single, 100-pin, high-density pitch
(0.635 mm) connector, allowing the phyCARDs to be plugged like a
"big chip" into a target application. The reduced complexity of the
phyCARD SBC as well as the smaller number of interface signals
greatly simplifies the SBC carrier board design helping you to reduce
your time-to-market.
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 approximately 20 % of all pin header connectors on the
X-Arc bus are dedicated to Ground. This improves EMI and EMC
characteristics and makes it easier to design complex applications
meeting EMI and EMC guidelines using phyCARD boards even in
high noise environments.
