Condition/Note
Voltage regulator to digital part off, register values retained
(SLEEP state). All GDO pins programmed to 0x2F (HW to 0)
Voltage regulator to digital part off, register values retained, low-
power RC oscillator running (SLEEP state with WOR enabled)
Voltage regulator to digital part off, register values retained,
XOSC running (SLEEP state with MCSM0.OSC_FORCE_ON set)
Voltage regulator to digital part on, all other modules in power
down (XOFF state)
Automatic RX polling once each second, using low-power RC
oscillator, with 460 kHz filter bandwidth and 250 kBaud data rate,
th
PLL calibration every 4 wakeup. Average current with signal in
channel below carrier sense level (MCSM2.RX_TIME_RSSI=1).
Same as above, but with signal in channel above carrier sense
level, 1.95 ms RX timeout, and no preamble/sync word found.
Automatic RX polling every 15
oscillator, with 460 kHz filter bandwidth and 250 kBaud data rate,
th
PLL calibration every 4 wakeup. Average current with signal in
channel below carrier sense level (MCSM2.RX_TIME_RSSI=1).
Same as above, but with signal in channel above carrier sense
level, 29.3 ms RX timeout, and no preamble/sync word found.
Only voltage regulator to digital part and crystal oscillator running
(IDLE state)
Only the frequency synthesizer is running (FSTXON state). This
current consumption is also representative for the other
intermediate states when going from IDLE to RX or TX, including
the calibration state.
