32K crystal-less mode: PG2.2 or PG2.3?

Other Parts Discussed in Thread: BLE-STACK, CC2640

For BLE-Stack v2.2, in order to use the 32K crystal-less mode, the SWRU393_CC2640_BLE_Software_Developer's_Guide, section 6.6 says to use silicon revision PG2.2 or later, but SWRA499, section 2.1 says to use silicon revision PG2.3 or later. Which is it? Thanks.

Hello Danny,
You need PG2.3 or later for crystal-less. Read section "2.1 CC2640 Hardware Revision" in the app note: Running Bluetooth® Low Energy on CC2640 Without 32 kHz Crystal.

Hi Danny,

That is a type-o in the SW Developer's Guide - sorry about that. As Eirik correctly states, PG2.3 is required. This is also noted in the release notes for BLE-Stack 2.2.0.

I apologize for the confusion.

Best wishes
