The numbered matrix can be aligned with the
phyCORE-LPC2292/94 (viewed from above; phyCORE-connector
pointing down) or with the socket of the corresponding phyCORE
Carrier Board/user target circuitry. The upper left-hand corner of the
numbered matrix (pin 1A) is thus covered with the corner of the
phyCORE-LPC2292/94 marked with a white triangle. The numbering
scheme is always in relation to the PCB as viewed from above, even if
all connector contacts extend to the bottom of the module.
The numbering scheme is thus consistent for both the module’s
phyCORE-connector as well as mating connectors on the phyCORE
Carrier Board 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 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 socketed connector.
The location of row 1 on the board is marked by a white triangle on
the PCB to allow easy identification.
