• Corrected Output programmable voltage range maximum value from 5.2V to 3.3V.

• Corrected Output voltage accuracy conditions from 1.8V ≤ VOA ≤ 5.0V to 1.8V ≤ VOA ≤ 3.3V.

• Removed Wired Buck Configuration from 4.1 Device Configurations and Table 3.2 DCDC A Configuration and Modes Summary on

page 9.

• Corrected all OPNs in Table 3.2 DCDC A Configuration and Modes Summary on page 9 and 2. Ordering Information.

• Corrected valid OTP_TEMP_CODE and OTP_OPN_NUM enumerations in 7.1 OTP Definition.

• Corrected EFP0109 Input Voltage Range in Table 2.1 Ordering Information on page 3.

• In Figure 4.6 Boost Bootstrap Configuration on page 35, corrected VOB output capacitor from 2.2µF to 10µF, added note about VOA

capacitor value, added notes on VOC Output capacitors.

• In 4.1.5 Wired Boost Configuration (EFP0109 & EFP0110), added clarification of VOB output capacitor size and added notes on

VOC Output capacitors.

• In 4.1.4 Single-Cell Boost Configuration (EFP0108) and 4.1.3 Buck/Boost Configuration (EFP0106 & EFP0107) , added notes on

VOC Output capacitors.

• Added VOB = 1.8V Output Voltage Accuracy Specs for the EFP0109 VOB output.

• In all VOB and VOC Electrical Specification tables, clarified footnote indicating that when VDDB was powered by VOA (EFP0108

and EFP0111), the DCDC B and LDO C output current is also limited by the VOA output current.

• Added dislaimer clarifying that Maximum Output Current formulas are not a guarantee of performance to the DCDC A Peak Current

Configuration, DCDC B Peak Current Configuration, and LDO Maximum Output Current sections.

• In 5.1.3.8 EFP0111 Electrical Specifications, corrected Maximum output current footnote test current (1.25mA instead of 5mA) and

added details on how to interpret this specification for Boost Bootstrap.

• Added note to 3.3.4 EM4 section that dedicated EM4 hardware support was available for EFP01 starting on EFR32xG22 devices.

• Clarified recommended reset mechanisms and hazards in 3.5.1 OTP section and 6.2.11 CMD register description.
