Re: SMPS will cause spike current ?

Hi All,

Our wireless short range communication is in standby mode now,
however, the software is working, should be no anything to do. ( I
want to indicate the s/w level is still alive, but nothing to do )

I got spike current in the duration of standby mode, I can't make sure
that is because NOP command ( or other not really important
commands) in the s/w level or h/w components effect it.

Any idea about read / write a EEPROM value will cause spike current
about 7mA, is it possible ?

Any idea about change a PIO will cause a spike current about 7mA ?

The module work at 1.8V at core chip, however, it accept 4.2V battery
voltage, it should has its own regulator. The PIO output I got is 3V.
The normal normal standby current is 1.5mA range.

Please let me know if I have to input more info.

Thanks!

Best regards,
Boki.

Any part numbers for us to evaluate, boki?
