2405011529 Additional Source for EFR32xG21 SoCs, Datasheet and Errata Updates
■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.
■Reason for Change
●Alternate foundry for capacity expansion.
■Impact on Form, Fit, Function, Quality, Reliability
●No impact on form, fit, quality or reliability. Impact on function will be explained in errata and an update to the new software that will need to be ported which is explained in the application note “AN1377: EFR32xG21 Revision B to Revision C+ Compatibility and Migration Guide".
