Die shots of EZRadioPRO and EZRadio chips #1

Open astuder opened 5 years ago

It would be great to have die shots of EZRadioPRO and EZRadio chips to verify whether they all share the same hardware as suspected. There may also be fuses to disable TX and PA on certain models. Specifically, I'm looking for:

Also of interest are EZR32x, Si106x, Si108x radio MCU combos, though I suspect they have separate MCU and radio dies inside.

On the die shots we have so far, the digital section of the IC is hidden under the top metal layer. Further analysis will require delayering the IC.

Added higher resolution die shot of Si4362-C2A, courtesy Travis Goodspeed. Digital sections still hidden. No obvious fusing of TX or PAs visible.
