4 Electrical Specifications
4.1 Current Consumption
Tc = 25°C, VDD = 3.0V if nothing else stated. All measurement results are obtained using the CC1101EM reference designs
([5] and [6]).
Reduced current settings (MDMCFG2.DEM_DCFILT_OFF=1) gives a slightly lower current consumption at the cost of a
reduction in sensitivity. See
for additional details on current consumption and sensitivity.

9.8
µA
Automatic RX polling once each second, using low-power RC
oscillator, with 460 kHz filter bandwidth and 250 kBaud data rate,
PLL calibration every 4
th
wakeup. Average current with signal in
channel below carrier sense level (MCSM2.RX_TIME_RSSI=1).
34.2
µA
Same as above, but with signal in channel above carrier sense
level, 1.95 ms RX timeout, and no preamble/sync word found.
1.5
µA
Automatic RX polling every 15
th
second, using low-power RC
oscillator, with 460kHz filter bandwidth and 250 kBaud data rate,
PLL calibration every 4
th
wakeup. Average current with signal in
channel below carrier sense level (MCSM2.RX_TIME_RSSI=1).
39.3
µA
Same as above, but with signal in channel above carrier sense
level, 29.3 ms RX timeout, and no preamble/sync word found.
1.7 mA Only voltage regulator to digital part and crystal oscillator running
(IDLE state)
Current consumption
8.4 mA Only the frequency synthesizer is running (FSTXON state). This
currents consumption is also representative for the other
intermediate states when going from IDLE to RX or TX, including
the calibration state.
