This is the static specification to ensure low current.
Output current of 2mA.
Output current of -2mA.
Excludes power used to drive external loads. Includes operation of the 32 KHz watch crys-
tal oscillator.
Device operation suspended by use of the low power controller with VDD and RTCVDD
within specification. Frequency of system clock (fclk) is 16.368 MHz and frequency of low
power clock is 32768 Hz.
With RTCVDD within specification and VDD at 0 V. All inputs static except LowPower-
ClockIn and LowPowerClockOsc, frequency of low power clock 32768 Hz. All other
inputs must be in the range -0.1 to 0.1 V.
Positive supply voltage during normal operation.
Positive supply voltage when device is off but real time
clock is running.
Voltage at RTCVDD pin referred to GND.

Input capacitance (input only pins).
Output capacitance and capacitance of bidirectional pins.
Operational power consumption under heavy device
activity. fclk of 16.368 MHz and SpeedSelect set to PLL
operation (x1). No external memory used.
Operational power consumption under ‘typical’ device
activity. fclk of 16.368 MHz and SpeedSelect set to PLL
operation (x2). External memory used.
Operational power during stand-by.
Operational power for the real time clock only, supplied
through the RTCVDD pin.
