208 / 241 page  208 Rev 1.3 An external 1.8 V regulator may replace both internal regulators. The EM35x can control external regulators during deep sleep using open-drain GPIO PA7, as described in "7. GPIO (General Purpose Input/Output)" on page 50. The EM35x drives PA7 low during deep sleep to disable the external regulator, and an external pull-up is required to release this signal to indicate that supply voltage should be provided. Current consumption increases approximately 2 mA when using an external regulator. When using an external regulator, the internal regulators should be disabled through Ember software. The always-on domain needs to be minimally powered at 2.1 V and cannot be powered from the external 1.8 V regulator. |
