I
referred to as power-down current. These tests are taken with all I/O as inputs, either pulled high
or low. That is, there are no floating inputs, nor are any pins driving an output (with a load).
The characterization shows graphs for both the Watchdog Timer (WDT) disabled and enabled.
This is required since the WDT requires an on-chip RC oscillator which consumes additional cur-
rent.
Since the device may have certain features and modules that can operate while the device is in
sleep mode. Some of these modules are:
• Watchdog Timer (WDT)
• Brown-out Reset (BOR) circuitry
• Timer1
• Analog to Digital converter
• LCD module
• Comparators
• Voltage Reference
If these features are operating while the device is in sleep mode, a higher current will be con-
sumed. When all features are disabled, the device will consume the lowest possible current (the
leakage current). If more then one feature is enabled then the expected current can easily be cal-
culated as the base current (everything disabled and in sleep mode) plus all delta currents.
