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.
