(1) TX power level = 0 implies maximum power (see Figure 4-1, Figure 4-2, and Figure 4-3). TX power level = 4 implies output power
backed off approximately 4 dB.
(2) The CC3220x system is a constant power-source system. The active current numbers scale based on the VBAT voltage supplied.
(3) DTIM = 1
(4) LPDS current does not include the external serial flash. The LPDS number of reported is with retention of 256KB of MCU SRAM. The
CC3220x device can be configured to retain 0KB, 64KB, 128KB, 192KB, or 256KB of SRAM in LPDS. Each 64-KB block of MCU
retained SRAM increases LPDS current by 4 µA.
(5) The complete calibration can take up to 17 mJ of energy from the battery over a period of 24 ms. Calibration is performed sparingly,
typically when coming out of HIBERNATE and only if temperature has changed by more than 20°C. The calibration event can be
controlled by a configuration file in the serial flash..
