1. Given in Table 10.1, “Reset Electrical Characteristics,” on page 105.
3. SYSCLK must be at least 32 kHz to enable debugging.
4. Based on device characterization data; Not production tested.
5. IDD can be estimated for frequencies < 15 MHz by simply multiplying the frequency of interest by the
2. USB requires a minimum supply voltage of 3.0 V.
6. 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 IDD for >15 MHz, the
estimate should be the current at 24 MHz minus the difference in current indicated by the frequency sensitivity
number. For example: VDD = 3.0 V; F = 20 MHz, IDD = 9.0 mA – (24 MHz –
frequency sensitivity number for that range. When using these numbers to estimate Idle IDD for >1 MHz, the
estimate should be the current at 24 MHz minus the difference in current indicated by the frequency sensitivity
number. For example: VDD = 3.0 V; F = 5 MHz, Idle IDD = 4.6 mA – (24 MHz –
20 MHz) x 0.26 mA/MHz = 7.96 mA.
5 MHz) x 0.17 mA/MHz = 1.37 mA.
