Notes:
1. Given in Table 10.1 on page 104.
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
frequency sensitivity number for that range. When using these numbers to estimate I_DD 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: V_DD = 3.0 V; F = 20 MHz, I_DD = 7.8 mA - (25 MHz -
20 MHz) * 0.21 mA/MHz = 6.75 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 I_DD 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: V_DD = 3.0 V; F = 5 MHz, Idle I_DD = 4.8 mA - (25 MHz -
5 MHz) * 0.15 mA/MHz = 1.8 mA.

peripherals. For more information on electrical characteristics for a specific peripheral, refer to the page
