I am beginner in PSOC. I am trying to program CY8CMBR3110 using Miniprog-3 by I2C protocol. In EZ-Click 2.0, when i try to select I2C target on 5v, It can't identify it. but if i select 2.5v or 1.8v, It identify device. So i do't understand what is problem. I attach circuit diagram.

Hi Sujit,
I think the problem is with pull-up resistance values.MiniProg3 already has internal pull-up resistances, so can you unmount reisitors on board and try?
Thanks

Hi Sujit,
*Try unmounting regulator and see result.
* See I2C waveforms with 5V .
* Try with BCP
1)List devicewith BCP
2)Send R to device address directly with BCP.

Hello Bharadhwaj,
-> I varify after mount MBR3 and its required capacitors and resistors, But problem continue.
-> I get some pulses at I2c pins when connect Mniprog-3 to MBR3.
-> BCP can't show my device on 5v. when i select 2.5v it showing device.
