    (SMT) connectors (0.635 mm) lining two sides of the module (referred to as phyCORE-connector). This allows the phyCORE-TC1796 to be plugged into any target application like a "big chip". A new numbering scheme for the pins on the phyCORE-connector has been introduced with the phyCORE specifications.
  • Page 16 Development Board/user target circuitry. The upper left-hand corner of the numbered matrix (pin 1A) is thus covered with the corner of the phyCORE-TC1796 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.
  • Page 17 Pin Description The following figure (Figure 4) illustrates the numbered matrix system. It shows a phyCORE-TC1796 with SMT phyCORE- connectors on its underside. Figure 4: Pinout of the phyCORE-Connector (view from Connector Side) Many of the controller port pins accessible at the connectors along the edges of the board have been assigned alternate functions that can be activated via software.
