Notes:
1. Typical data are based on TA=25°C, VDD=5V (4.5V≤VDD≤5.5V range) and VDD=3.4V (3.2V≤VDD≤3.6V range).
2. Data based on characterization results, tested in production at VDD max. and fCPU max.
3. All I/O pins in input mode with a static value at VDD or VSS (no load), all peripherals in reset state; clock input (OSC1)
driven by external square wave, CSS and LVD disabled.
4. SLOW-WAIT mode selected with fCPU based on fOSC divided by 32. All I/O pins in input mode with a static value at
VDD or VSS (no load), all peripherals in reset state; clock input (OSC1) driven by external square wave, CSS and LVD
disabled.
