2 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.
As
Figure 4 indicates, all controller signals selected extend to surface mount technology
(SMT) connectors (0.5 mm) lining two sides of the module (referred to as
phyCORE-Connector). This allows the phyCORE-i.MX 6 to be plugged 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. The pin
numbering values increase moving down on the board (
Figure 4 ).
The numbered matrix can be aligned with the phyCORE-i.MX 6 (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 X1C1) is thus covered with the corner of the phyCORE-i.MX 6. 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 the mating connector 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 following figure illustrates the numbered matrix system. It shows a phyCORE-i.MX 6
with both SMT phyCORE-Connectors on its underside (defined as dotted lines) mounted on
a carrier board. In order to facilitate understanding of the pin assignment scheme, the
diagram presents a cross-view of the phyCORE-i.MX 6 module showing the phyCORE-
Connector mounted on the underside of the module’s PCB.
Table 3 to Table 6 provide an overview of the pinout of the phyCORE-Connector X1 with
signal names and descriptions specific to the phyCORE-i.MX 6. It also provides the
appropriate voltage domain, signal type (ST) and a functional grouping of the signals. The
