Difference in nRF51822 chip revisions

[Karl]

Hi guys,

i tried to find information about the differences in chip revision nRF51822-QFAA-R7, NRF51822-QFAA-T and nRF51822-QFAA-G0 but i can't find the R7 or T type anywhere. Can somebody help me find the right information or point out the differences?

Regards

Hi Karl

The G0 refers to the version of the chip itself while the R7 and T refer to the packaging of those chips. This thread says a lot about how to realize different nRF51 chip versions.

digikey.com provides the nRF51822 in different packages, see here. There you have Tray packaging, Tape & reel, etc. If you click on the question marks in the packaging column, it explains a bit about the difference between those packaging.
