Notes
:
(1) TX power level = 0 implies maximum power. 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 reported is with retention of 64 KB MCU
SRAM. The CC3220 device can be configured to retain 0 KB, 64 KB, 128 KB, 19 2KB or 256 KB SRAM in LPDS. Each
64 KB retained increases LPDS
current by 4 μA.
(5) The complete calibration can take up to 17 mJ of energy from the battery over a time of 24 ms. Calibration is
performed sparingly, typically when coming out of Hibernate and only if temperature has changed by more than 20°C or
the time elapsed from prior calibration is greater than 24 hours.
