Notes:
1) Unless otherwise specified, typical data are based on TA=25°C and VDD-VSS=5V. They are given only as design guide-
lines and are not tested.
2) CPU running with memory access, all I/O pins in input mode with a static value at VDD or VSS, all peripherals switched
off; clock input (OSC1) driven by external square wave.
3) All I/O pins in input mode with a static value at VDD or VSS, all peripherals switched off; clock input (OSC1) driven by
external square wave.
4) All I/O pins in input mode with a static value at VDD or VSS, LVD disabled.
5) Data based on characterization results, not tested in production.
6) ∆tINST is the number of tCPU to finish the current instruction execution.
