SUPPLY CURRENT CHARACTERISTICS (Cont’d)
12.4.2 Wait and Slow-wait Modes
Figure 133. Typical I
Notes:
1. Data based on characterization results, tested in production at V
2. Measurements are done in the following conditions:
- Program executed from RAM, CPU running with RAM access. The increase in consumption when executing from Flash
is 50%.
- All I/O pins in input mode with a static value at V
- All peripherals in reset state.
- LVD disabled.
- Clock input (OSC1) driven by external square wave.
- In Slow and Slow-wait mode, f
