28.5.1 Sleepy Mode Current Consumption
The Rabbit 4000 supports designs with very low power consumption by using features
such as the ultra-sleepy modes and self-timed chip selects. At the low frequencies possible
in the ultra-sleepy modes (as low as 2 kHz), the external memory devices become signifi-
cant factors in the current consumption unless one of the short or self-timed chip selects
are used.
Figure 28-6 shows a typical current draw for the ultra sleepy modes.
