New SX1276 chip revision with REG_VERSION=0x13

Semtech Transceivers SX127x family
#1

It was found out recently that certain new SX1276 production batches have 0x13 value stored in the REG_VERSION register.
According to the datasheet ‘minor number’ (bits 0-3) change means 'update of metal layer’.

Is there any chance to read ‘Errata’ for both regular (0x12) and new (0x13) revisions of the SX1276 silicon?

Hello @xkremator,

Can you please tell me in which condition you observed this value? Is it on a chip directly or with a module?

Thanks.

0x13 value is reported by most recent AcSip S76 SiP revision.
