SUPPLY CURRENT CHARACTERISTICS (Cont’d)

12.4.2 WAIT and SLOW WAIT Modes

Figure 133. Typical IDD in WAIT vs. fCPU

Figure 134. Typical IDD in SLOW-WAIT vs. fCPU

Notes:

1. Data based on characterization results, tested in production at VDD max. and fCPU max.

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 VDD or VSS (no load)

- All peripherals in reset state.

- LVD disabled.

- Clock input (OSC1) driven by external square wave.

- In SLOW and SLOW WAIT mode, fCPU is based on fOSC divided by 32.

To obtain the total current consumption of the device, add the clock source (Section 12.5.3) and the peripheral power

consumption.
