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 phyFLEX bus signals extend to up to three
surface mount technology (SMT) connectors (0.5 mm) (referred to as
phyFLEX-Connector). This allows the phyFLEX-i.MX 6 to be
plugged into any target application like a "big chip". As well the
location of the commonly used interfaces as the mechanical
specifications of the connectors are clearly defined.
The first connector X1 is called phyFLEX-fix connector. All
phyFLEX SOMs support all interfaces specified for this connector at
the same locations. The second connector X2, called phyFLEX-
optional connector, has optional, but defined interfaces at fixed
positions (e.g. SATA, CAN, camera). phyFLEX SOMs can, but do not
have to support the interfaces at the phyFLEX-optional connector. The
third connector, phyFLEX-flex connector X3, has only fixed Ground
signals. All other signals of the phyFLEX-flex connector are module
specific and depend on the features of the controller populating the
SOM.
The numbering scheme for the phyFLEX-Connector is based on a two
dimensional matrix in which column positions are identified by a
letter and row position by a number with prefixed Connector
Reference (X1=phyFLEX-fix, X2=phyFLEX-optional,
X3=phyFLEX-flex). Pin X1A1, for example, is always located in the
upper left hand corner of the matrix of connector X1. 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).
