Notes:

1. The values do not include I/O supply power (OVDD and GVDD), but it does include VDD and AVDD power. For I/O power values,

see Table 6.

2. Typical power is based on a nominal voltage of VDD = 1.0 V, ambient temperature, and the core running a Dhrystone

benchmark application. The measurements were taken on the evaluation board using WC process silicon.

3. Maximum power is based on a voltage of VDD = 1.05 V, WC process, a junction TJ = 105°C, and a smoke test code.
