8 / 94 page CC1101 SWRS061B Page 8 of 93 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. Parameter Min Typ Max Unit Condition 0.2 1 µA Voltage regulator to digital part off, register values retained (SLEEP state). All GDO pins programmed to 0x2F (HW to 0) 0.5 µA Voltage regulator to digital part off, register values retained, low- power RC oscillator running (SLEEP state with WOR enabled 100 µA Voltage regulator to digital part off, register values retained, XOSC running (SLEEP state with MCSM0.OSC_FORCE_ON set) Current consumption in power down modes 165 µA Voltage regulator to digital part on, all other modules in power down (XOFF state) 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. 15.4 mA Receive mode, 1.2 kBaud, reduced current, input at sensitivity limit 14.4 mA Receive mode, 1.2 kBaud, reduced current, input well above sensitivity limit 15.2 mA Receive mode, 38.4 kBaud, reduced current, input at sensitivity limit 14.3 mA Receive mode,38.4 kBaud, reduced current, input well above sensitivity limit 16.5 mA Receive mode, 250 kBaud, reduced current, input at sensitivity limit 15.1 mA Receive mode, 250 kBaud, reduced current, input well above sensitivity limit 27.4 mA Transmit mode, +10 dBm output power 15.0 mA Transmit mode, 0 dBm output power Current consumption, 315MHz 12.3 mA Transmit mode, –6 dBm output power |
