Notes:
2. SYSCLK must be at least 32 kHz to enable debugging.
3. Based on device characterization data; Not production tested.
4. Normal IDD can be estimated for frequencies <= 15 MHz by simply multiplying the frequency of interest by
the frequency sensitivity number for that range. When using these numbers to estimate IDD for >15 MHz, the
estimate should be the current at 25 MHz minus the difference in current indicated by the frequency sensitivity
number.
For example: VDD = 3.0 V; F = 20 MHz, IDD = 6.6 mA – (25 MHz – 20 MHz) x 0.16 mA/MHz = 5.8 mA.
5. Idle IDD can be estimated for frequencies <= 1 MHz by simply multiplying the frequency of interest by the
frequency sensitivity number for that range. When using these numbers to estimate Idle IDD for >1 MHz, the
estimate should be the current at 25 MHz minus the difference in current indicated by the frequency sensitivity
number.
For example: VDD = 3.0 V; F = 5 MHz, Idle IDD = 3.3 mA – (25 MHz – 5 MHz) x 0.10 mA/MHz = 1.3 mA.
