Frequently Asked Questions
1. How does CY8CPROTO-062S3-4343W handle voltage connection when multiple power sources
are plugged in?
There are 3 different options to power the baseboard; KitProg3 Micro-B USB connector
(J8)
,
PSoC 6 Micro-B USB connector
(J10)
and External DC supply via VCC_5V input header
(J9)
.
The voltage from each of the USB connectors passes through a current limiting switch that also
protects against reverse voltage. Optionally, P6_VDD can be supplied by an external
programmer / debugger at J11. This is not loaded by default and is not recommended as not all
peripherals will be powered.
2. What are the input voltage tolerances? Is there any overvoltage protection on this kit?
Input voltage level are as follows:
There is no overvoltage protection on this kit.
3. Why is the voltage of the kit restricted to 3.3 V? Can’t it drive external 5 V interfaces?
PSoC 6 MCU is not meant to be operated at voltages greater than 3.6 V. Hence, it cannot drive
I/O system with > 3.6 V supply voltages. Powering PSoC 6 MCU to more than 4 V will damage
the chip.
4. I am unable to program the target device.
a. Check J3 to ensure that a jumper shunt is placed.
b. Make sure that no external devices are connected to J2.32 to J2.36.
c. Update your KitProg3 version to the latest version using the steps mentioned in the
d. Ensure that target device used in the IDE application is CY8C6245LQI-S3D72.
5. Does the kit get powered when I power the kit from another Cypress kit through the
J9
header?
Yes, VIN pin on
J9
header is a supply input/output pin and can take up to 5.5V.
6. What additional overlays can be used with the CapSense?
Any kind of overlays (up to 5 mm thickness) like wood, acrylic, and glass can be used with this
CapSense. Note that additional tuning may be required when the overlay is changed.
7. Can I use this kit as a programmer to program external PSoC devices?
Yes, the onboard KitProg3 can program any PSoC 4/5/6 devices connected to
J5
header, once it
is broken away from the PSoC 6 MCU section of the board.
8. Which third-party IDEs does this Kit support?
Multiple third-party IDEs are supported; IAR and µVision are some examples. For more details on
all supported devices and procedures to export to these IDEs, see
Toolbox Software with a Third-Party IDE
