Description of Change
Silicon Labs is pleased to announce an additional source for EFR32BG21 and EFR32MG21 SoCs (jointly referred to as xG21)
at Semiconductor Manufacturing International Corporation (SMIC). This change is needed to increase capacity to ensure supply
continuity due to increased demand for our Wireless SoCs and MCUs.
As of the effective date of this PCN, Silicon Labs will start porting xG21 from TSMC to SMIC. All existing OPNs will be updated
by replacing the revision character with “D” to identify the ICs from SMIC foundry.
Updated datasheets:
EFR32BG21 v1.2: https://www.silabs.com/documents/public/data-sheets/efr32bg21-datasheet.pdf
EFR32MG21 v1.2: https://www.silabs.com/documents/public/data-sheets/efr32mg21-datasheet.pdf
The main changes:
• Added all Revision D OPNs.
• Capacitive Sense feature of ACMP has been noted as deprecated.
• Merged xG21 (Secure Vault Mid) & xG21B (Secure Vault High) datasheets
Please refer to the datasheet revision history for a complete list of changes.
Updated errata (adds the latest available revision D):
