3.3 Power Supply Operating Characteristics (pre- and post-radiation)

VDD = 3.3V + 0.3V; VDDC = 2.5V + 0.2V; TC = -40

oC to 105oC)

Notes:

1. During this measurement the processor is executing the Dhrystone benchmark.

2. This measurement includes the contribution due to IDDCS.

3. This measurement includes the contribution due to IDDS.

4. Power-down mode is entered by performing a WRASR instruction wr %g0, %asr19.
