There is a USB Type A port on the shield board to demonstrate high speed USB
operation. The Type A port is connected to the Type C port through PTN36043, USB3.1
Gen 1 redriver. It is intended to demonstrate the USB operation in a Host system. If
the Host system FW is installed in the KL27 Freedom board then the user can connect
the USB port on the KL27 to the shield board using a miniB to A cable from J10 on the
Freedom board to J2 on the shield board. Now if a USB device is plugged into the Type
C connector the user should be able to see the flash drive enumerate in the Host system.
3.2 Hardware setup for CC Logic operation
The Shield board also supports simple CC logic implementation over USB Type-C.
Users need to disable the PTN5110 and to enable PTN5150 connection to CC1/CC2
by modifying J13 and J14. Disconnect the 9V AC/DC power adaptor input to the shield
board, because PTN5150A only supports 5V. The PTN5150A has hardware input
strapping pin#3 (TP11) to configure its power up default mode: DRP, DFP or UFP. Since
PTN5150A does not support power delivery, the KL27 can disable TCPM firmware from
the stack. KL27 can access PTN5150A I2C register for additional information. When
PTN5150A is configured as DRP or UFP, it supports dead battery mode startup. When a
power source is plugged into a shield board, PTN5150A will present 5.1Kohm pull down
on CC1/CC2. The shield board receives 5V from the USB Type-C connector. PTN5150A
sends a signal (TP9) to turn on the Sink Path load switch.
The jumper settings for setting the board for CC logic operation is given below. Please
remove all the other shunts on the board.
1. Install shunt at J6
2. Install shunt at J13 – Pin 3 to 2
3. Install shunt at J14 – Pin 3 to 2
When operating in this mode the shield board does not need to plug in to the KL27
Freedom board. Power up the Shield board using the 9V Power Adaptor. Please refer to
PTN5150 product datasheet for more details.
3.3 Authentication
The shield board also has a Secure Authentication IC, A1006 on the I2C line. The
Authentication IC can be used to implement Authentication through Type C. Please
check with your NXP Account Manager for details on A1006.
3.4 Dead battery operation
The shield board can be used to demonstrate dead battery operation using PTN5110
or PTN5150A. Notebook and smartphone applications will need TCPC to enable
the Sink path when a charger is plugged into the Type C port even when the PD
controller (TCPM) is not enabled. PTN5110 can automatically detect dead battery
situation and enable the sink FET during dead battery boot up. Please contact your NXP
representative if you need more info on dead battery operation.
