4
Output current of -2mA.
Excludes power used to drive external loads. Includes operation of the 32 KHz watch crys-
tal oscillator.
5
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.
