1. Given in Table 10.1 on page 102.
2. SYSCLK must be at least 32 kHz to enable debugging.
3. Based on device characterization data; Not production tested.
4. IDD can be estimated for frequencies <= 15 MHz by simply multiplying the frequency of interest by the
5. Idle IDD can be estimated for frequencies <= 1 MHz by simply multiplying the frequency of interest by the

Supply Sensitivity (Note 3) F = 25 MHz
Frequency Sensitivity
frequency sensitivity number for that range. When using these numbers to estimate I
estimate should be the current at 25 MHz minus the difference in current indicated by the frequency
sensitivity number. For example: V
frequency sensitivity number for that range. When using these numbers to estimate Idle I
estimate should be the current at 25 MHz minus the difference in current indicated by the frequency
sensitivity number. For example: V
20 MHz) * 0.21 mA/MHz = 6.75 mA.
5 MHz) * 0.15 mA/MHz = 1.8 mA.
