Device Current Specifications
I
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).
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), weak
pull-ups are disabled.
A device may have certain features and modules that can operate while the device is in sleep
mode. Some on these modules are:
• Watchdog Timer (WDT)
• Brown-out Reset (BOR) circuitry
• Timer1
• Analog to Digital converter
• LCD module
• Comparators
• Voltage Reference
When all features are disabled, the device will consume the lowest possible current (the leakage
current). If any of these features are operating while the device is in sleep, a higher current will
occur. The difference between the lowest power mode (everything off) at only that one feature
enabled (such as the WDT) is what we call the Module Differential Current. If more then one
feature is enabled then the expected current can easily be calculated as: the base current (every-
thing disabled and in sleep mode) plus all Module Differential Currents (delta currents).
