Hi Team,
We are designing a board using the MCU CY8C6247FTI-D52T.
1 x UART = SCB7, TX - P1[0], RX - P1[1]
2 x I2C = SCB5, SCL - P5[0], SDA - P5[1]
SCB8, SCL - P6[0], SDA - P6[1]
16 x GPIO
3 x Analog Read = P10[1], P10[4], P10[5]
1 x Analog Write = P10[0]
are used.
SWD is the debugging interface. -
SWDIO - P6[6]
SWCLK - P6[7]
XRES
SWO - P6[4]
32KHz RTC OScillator - P0[0], P0[1]
High-speed oscillator - P12[6], P12[7]
The schematic is attached herewith.
Please let me know if there are any mistakes.
Solved! Go to Solution.

Hi @shibin,
I have gone through your schematic and the following are my observations:
- Pin connections are correct.
- SCB blocks are used correctly.
- Only connect 4.7 uF capacitor close to the VBUCK1 and for the VCCD just short it with VBUCK1 (C53, 56 and 57 are not required)
- VDDA has an additional 1 uF capacitor, which is not required.
- The VBACKUP doesn’t require a 10uF capacitor.
- It is recommended to use a 330-Ohm series resistance directly connected to the pin before 4.7 kOhm Pull up resistance for i2c.
- For DEBUG interface if you are using 10 pin connector then connect all signals required for it as given in “PSoC 6 Hardware Design Consideration”
- For i) ECO P12.6 = ECO_IN, P12.7 = ECO_OUT ii) WCO P0.0 = WCO_IN, P0.1 = WCO_OUT
Please, let me know if any further clarification is required.
Thank you
Best Regards

Hi Raj,
Thank you for your reply
1). The VBACKUP pin is supplied from the same source that powers the VDDD pin.
2). We are not using a USB, so the pin VDDUSB has connected to the same power supply that powers the VDDD pin.
3). I believe the ECO and the WCO pins are correct and their load capacitors.
ECO - LFXTAL063075BULK, load capacitance - 22pF
WCO - CM9V-T1A-32.768kHz-12.5pF-
I hope this will suffice. DEV KIT - PSoC® 6 WiFi-BT Pioneer Kit (CY8CKIT-062-WiFi-BT) (cypress.com)
