【PCN】SILICON LABS Addendum to 190123442 EFM8BB3 Silicon Revision C Revision Change Notice (200519780)

PublishTime：2021-01-11

●Description of Change:
This addendum to PRCN 190123442 is being issued to extend the availability of revision B for the BB3 products due to large demand. This addendum does not affect the revision B availability for the LB1 products which have been announced End of Life (EOL PCN 200114699).
Original PRCN Change Description:
Silicon Labs is pleased to announce the release of silicon revision C for the EFM8 LB1 and BB3 products. Silicon Labs is also pleased to announce the release of version 1.3 of the EFM8LB1 and EFM8BB3 datasheets.
The device changes accompanied by this silicon revision are as follows:
-P0.3 will no longer drive low on startup or reset thus solving errata issue POR_E102.
-The device will no longer support the use of an external crystal oscillator but will still support external RC and CMOS oscillators
-Removed bits 6 and 7 from the XOSC0CN: External Oscillator Control Register, SFR Page 0x0, 0x10; SFR Address: 0x86
The changes to the datasheet are as follows:
-Updated ordering part numbers to revision C.
-Updated Section 1. Feature List, Figure 3.1 "Detailed EFM8LB1 Block Diagram" on page 8 to remove external oscillator input.
-Updated Section 3.4 Clocking to remove external crystal oscillator as clock source.
-Updated Section 4.1.8 External Oscillator from presenting specifications for crystal oscillators to present specifications for RC oscillators.
●Reason for Change:
Extend the availability of revision B for the BB3 products.
Original PRCN Change Reason:
This silicon change is to correct errata item POR_E102 which was a bug in the startup sequence of P0.3. See form, fit, function, quality, and reliability section below.
●Impact on Form, Fit, Function, Quality, Reliability:
The addendum does not add or change the impact on Form, Fit, Function, Quality, Reliability.
Original PRCN impact:
Systems that rely on an external crystal will need to re-architect their clocking structure to ensure revision C devices will function in the system. Systems that previously experienced a erroneous pull down on start up on P0.3 will no longer experience this on revision C devices.
