22.2.2 DC Current Consumption
VDD = 2.0 to 3.6V, -40 to +85º C
22.2.2.1 Active Processing
Mode: Min Typ Max Unit Notes
CPU processing
32,16,8 or 4MHz
1600 +
280/MHz
µA
SPI, GPIOs enabled. When in
CPU doze the current related to
CPU speed is not consumed.
Radio transmit 15.0 mA
CPU in software doze – radio
transmitting
Radio receive 17.5 mA
CPU in software doze – radio in
receive mode
The following current figures should be added to those above if the feature is being used
ADC 655 µA
Temperature sensor and battery
measurements require ADC
DAC 215 / 235 µA One / both
Comparator 73 / 0.8 µA Normal / low-power
UART 90 µA For each UART
Timer 30 µA For each Timer
2-wire serial interface 70 µA
22.2.2.2 Sleep Mode
Mode: Min Typ Max Unit Notes
Sleep mode with I/O wakeup 0.12 µA Waiting on I/O event
Sleep mode with I/O and RC
Oscillator timer wakeup –
measured at 25ºC
1.25 µA
As above, but also waiting on timer
event. If both wakeup timers are
enabled then add another 0.05µA
32kHz crystal oscillator 1.5 µA As alternative sleep timer
The following current figures should be added to those above if the feature is being used
RAM retention– measured at
