Power Consumption Notes:
Note 1
This is for Peak Radio Current only, but there is additional current due to the MCU, refer to Table 12
and Table 15 for the peak and "Average Advert/connection (burst) current" consumption profile
(with DCDC on) during advertising and connection versus TX power. In smartBASIC runtime engine
firmware, use of the internal DCDC convertor or LDO is decided by the underlying BLE stack.
Note 2
BL652-Sx-xx: Standby Doze is 1.2uA typical. Standby Doze is entered automatically (when a waitevent
statement is encountered within a smartBASIC application script). In Standby Doze, all peripherals
