Pin Description
Please note that all module connections are not to exceed their expressed maximum voltage or current. Maximum signal
input values are indicated in the corresponding controller manuals/data sheets. As damage from improper connections
varies according to use and application, it is the user's responsibility to take appropriate safety measures to ensure that
the module connections are protected from overloading through connected peripherals.
All controller signals extend to surface mount technology (SMT) connectors (0.5 mm) lining two sides of the module
(referred to as the phyCORE-Connector). This allows the phyCORE-i.MX7 to be inserted into any target application like a
"big chip".
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 A1, for example, is located in the lower right hand corner of the
matrix looking down through the top of the SOM. The pin numbering values decrease moving down on the board. Lettering
of the pin connector columns progresses alphabetically from right to left for each connector (refer to
Figure 4
).
The numbered matrix can be aligned with the phyCORE-i.MX7 (viewed from above; phyCORE-Connector pointing down)
or with the socket of the corresponding phyCORE Carrier Board/user target circuitry. The lower right-hand corner of the
numbered matrix (pin A1) is thus covered with the corner of the phyCORE-i.MX7 marked with a 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 following figure illustrates the numbered matrix system. It shows a phyCORE-i.MX7 with SMT phyCORE Connectors
on its underside (defined with dotted lines) as it would be mounted on a Carrier Board. In order to facilitate understanding
of the pin assignment scheme, the diagram presents a cross-view of the phyCORE-module showing these phyCORE-
Connectors mounted on the underside of the module’s PCB.
