7. What are input voltage tolerances? Are there any overvoltage protection on this kit?
Input voltage level are as follows:
8. Why is the voltage of the kit restricted to 3.3 V? Can it drive external 5-V interfaces?
PSoC 6 is not meant to be powered for more than 3.6 V. Powering PSoC 6 to more than 3.3 V will
damage the chip. You cannot drive the I/O system with more than 3.3-V supply voltages.
9. I powered my Arduino board by mistake, while powering the PSoC 6 MCU. Is my PSoC 6 device
alive?
Yes. The 3.3 V and 5 V on Arduino power header are not input pins and have protection circuit to
prevent the voltage from entering the board. VIN is an input pin and this is routed to the regula-
tor, which is capable of taking an absolute maximum of 15 V. The P6.V
DD
pin is not protected
and care should be taken not to supply voltage to this pin.
10. What type of battery can I use for this kit?
The recommended lithium-ion polymer rating is 3.7 V at 850 mAH or higher. SparkFun Electron-
ics PRT-13854 or equivalent batteries can be used. The LiPo battery charger can charge at
100 mA or 1.5 mA based on whether the USB connection is a legacy device or PD-capable.
11. I connected the battery with the opposite polarity by mistake. Did I fry the system?
The kit has relevant protection circuits to protect the system from permanent damage. Prolonged
connection may lead to damage.
12. Can I charge any kind of Type-C device using this kit?
The kit is programmed to advertise the VIN voltage with 1 A current rating. 5-V and 12-V devices
are the recommended options. VIN needs to be 5 V and 12 V respectively for this to work.
13. How can I evaluate the USB Type-C provider and consumer features to get started?
You can use any kind of Type-C laptop, mobile phone, or PD adapters based on the feature that
you are trying to evaluate. When using as a consumer, note that devices such as laptops may be
able to provide only 5 V out and may not support 9 V/12 V without a docking station. To use as a
provider, any 5 V/9 V/12 V device that has a current requirement of less that 1 A may be used.
Additionally, Cypress has its own USB Type-C evaluation kit, which can be used to evaluate the
provider and consumer features and many more. Visit

14. I am unable to program the target device.
a. Ensure that SW7 is in VDDD/KITPROG2 position.
