Notes:

1. SYSCLK must be at least 32 kHz to enable debugging.

2. SYSCLK is the internal device clock. For operational speeds in excess of 30 MHz, SYSCLK must be derived

from the Phase-Locked Loop (PLL).

3. Based on device characterization data; Not production tested.

4. IDD can be estimated for frequencies < 20 MHz by simply multiplying the frequency of interest by the frequency

sensitivity number for that range. When using these numbers to estimate IDD for >20 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 = 15.9 mA - (25 MHz - 20 MHz) * 0.38 mA/MHz = 14 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 = 7.2 mA - (25 MHz - 5 MHz) * 0.25 mA/MHz = 2.2 mA.
