Please share us the project schematic in this thread.
We have tested our PSoC 3 kit at our side with your application code and found that the sleep current is less han 1 micro ampere. So we wold like to check you project schematic.

Thank you for your reaction!
In attachment you will find:
- the schematic and board layout
- a picture showing the board I used for current measurements, where I desoldered all components except the PSoC and the caps and xtal surrounding it.
Thank you in advance for all your suggestions and remarks!

Please check whether the PSoC itself is consuming 28uA or the current consumed from the entire circuitry is 28A. Please note that there will be leakage currents based on the components and board design. Please confirm this.
Regarding PSoC firmware side, enabling the external oscillators will draw more current. So please be aware of this.
Follow the kit schematics for CY8CKIT-001 and PSoC 3 module and design accordingly.
