A new numbering scheme for the pins on the phyCORE-connector
has been introduced with the phyCORE specifications. This enables
quick and easy identification of desired pins and minimizes errors
when matching pins on the phyCORE module with the receptacle
socket on the appropriate PHYTEC phyCORE Development
Board LD 5V or your OEM application.
The numbering scheme for the phyCORE-connector is based on a two
dimensional matrix in which column positions are identified by a
letter and row position by a number. Pin 1A, for example, is always
located in the upper left hand corner of the matrix. The pin numbering
values increase moving down on the board. Lettering of the pin
connector rows progresses alphabetically from left to right
(refer to Figure 4).
The numbered matrix can be aligned with the phyCORE-P8xC51Mx2
(viewed from above; phyCORE-connector header pins pointing
down) or with the socket of the phyCORE Development
Board LD 5V / target circuitry. The upper left hand corner of the
numbered matrix (Pin 1A) is thus covered with the corner of the
phyCORE-P8xC51Mx2 marked with a white triangle. The numbering
scheme is always in relation to the PCB as viewed from above, even if
all contacts extend to the bottom of the board.
The numbering scheme is thus consistent for both the module’s
phyCORE-connector as well as mating connectors on the phyCORE
Development Board LD 5V or target hardware, thereby considerably
reducing the risk of pin identification errors.
Since the pins are exactly defined according to the numbered matrix
previously described, the phyCORE-connector’s receptacle socket is
usually assigned a single designator for its position (X1 for example).
In this manner the phyCORE-connector comprises a single, logical
unit regardless of the fact that it could consist of more than one
physical connector. The location of row 1 on the board is marked by a
white triangle on the PCB to allow easy identification.
