CC25004 Electrical Specifications4.1 Current ConsumptionTc = 25°C, VDD = 3.0 V if nothing else stated. All measurement results obtained using the CC2500EM reference design([4]).Parameter Min Typ Max Unit ConditionCurrent consumption inpower down modes400 nA Voltage regulator to digital part off, register values retained(SLEEP state). All GDO pins programmed to 0x2F (HW to 0)900 nA Voltage regulator to digital part off, register values retained, lowpowerRC oscillator running (SLEEP state with WOR enabled)92 µA Voltage regulator to digital part off, register values retained,XOSC running (SLEEP state with MCSM0.OSC_FORCE_ON set)160 µA Voltage regulator to digital part on, all other modules in powerdown (XOFF state)Current consumption8.1 µA Automatic RX polling once each second, using low-power RCoscillator, with 460 kHz filter bandwidth and 250 kBaud data rate,PLL calibration every 4 th wakeup. Average current with signal inchannel below carrier sense level (MCSM2.RX_TIME_RSSI=1).35 µA Same as above, but with signal in channel above carrier senselevel, 1.95 ms RX timeout, and no preamble/sync word found.1.4 µA Automatic RX polling every 15 th second, using low-power RCoscillator, with 460 kHz filter bandwidth and 250 kBaud data rate,PLL calibration every 4 th wakeup. Average current with signal inchannel below carrier sense level (MCSM2.RX_TIME_RSSI=1).34 µA Same as above, but with signal in channel above carrier senselevel, 29.3 ms RX timeout, and no preamble/sync word found.1.5 mA Only voltage regulator to digital part and crystal oscillator running(IDLE state)7.4 mA Only the frequency synthesizer is running (FSTXON state). Thiscurrents consumption is also representative for the otherintermediate states when going from IDLE to RX or TX, includingthe calibration state.Current consumption,RX states17.0 mA Receive mode, 2.4 kBaud, input at sensitivity limit,MDMCFG2.DEM_DCFILT_OFF=014.5 mA Receive mode, 2.4 kBaud, input well above sensitivity limit,MDMCFG2.DEM_DCFILT_OFF=017.3 mA Receive mode, 10 kBaud, input at sensitivity limit,MDMCFG2.DEM_DCFILT_OFF=014.9 mA Receive mode, 10 kBaud, input well above sensitivity limit,MDMCFG2.DEM_DCFILT_OFF=018.8 mA Receive mode, 250 kBaud, input at sensitivity limit,MDMCFG2.DEM_DCFILT_OFF=015.7 mA Receive mode, 250 kBaud, input well above sensitivity limit,MDMCFG2.DEM_DCFILT_OFF=016.6 mA Receive mode, 250 kBaud current optimized, input at sensitivitylimit, MDMCFG2.DEM_DCFILT_OFF=113.3 mA Receive mode, 250 kBaud current optimized, input well abovesensitivity limit, MDMCFG2.DEM_DCFILT_OFF=119.6 mA Receive mode, 500 kBaud, input at sensitivity limit,MDMCFG2.DEM_DCFILT_OFF=017.0 mA Receive mode, 500 kBaud, input well above sensitivity limit,MDMCFG2.DEM_DCFILT_OFF=0SWRS040B Page 8 of 92
