Bulletin Details

Description:

Silicon Labs is pleased to announce that version 1.40 of the EFM32WGxxx (Wonder Gecko family)

datasheets are now available. The affected datasheets are: EFM32WG230, EFM32WG232,

EFM32WG280, EFM32WG290, EFM32WG295, EFM32WG330, EFM32WG332, EFM32WG380, EFM32WG390,

EFM32WG395, EFM32WG840, EFM32WG842, EFM32WG880, EFM32WG890, EFM32WG895, EFM32WG940,

EFM32WG942, EFM32WG980, EFM32WG990, EFM32WG995.

The revision includes a number of key changes to existing min/max/typ values that more accurately

reflect the performance of the part. These changes are summarized in Table 1 at the end of this

document. In addition, Table 3.12 HFRCO has a new Footnote 3, ensuring frequency bands above

7MHz will always have some overlap across supply voltage and temperature.

In addition, new min/max data has been added and other minor updates have been made as follows:



Removed "preliminary" markings throughout

Updated Current Consumption information

Updated Power Management information

Updated GPIO information

Updated HFXO information

Updated LFRCO information

Updated HFRCO information and figures

Updated ULFRCO information

Added AUXHFRCO chapter

Updated ADC information

Updated DAC information

Updated OPAMP information

Updated ACMP information

Updated VCMP information

Added EBI chapter

See Table 1 at the end of this document for additional details.

Reason:

Updated specifications based on the results of additional silicon characterization. There are no

changes to the devices delivered to the customer.

Product Identification:

The following orderable part numbers are affected:

EFM32WG230F64-QFN64
