It has been there since the beginning - UUP's sighting!
Well these wonderful pads of what seems to be an 8-pin ic, where there, next to the flash chip, on all wl500gP's, wl500w's and wl700gE's, waiting to be noticed...
What that IC might have been remains unclear...
If it was a real time clock, wouldn't it need a back-up battery? most probably yes.
An eeprom then...? but what it's use would be...?
Or do they give access to some internal pins of nearby chips...? Probably not since test points or connector awaiting pads would have been used in that case...
It seems (a wild guess) that there might be the signals of an I2C or an SPI presented there...
Having zero spare time now, it will take a while before I could have a chance to investigate this matter further...
The pads are know to belong to an IC nicknamed U12
If you can shed light on this case... we want to hear from you
Inertial
Bellow is a picture of the UUP's (Unidentified Unsoldered Pads) in question...
