Table 8
provides information for interface frequency limits.
3.4.1
Current Consumption
Table 9
defines the frequency settings used for specifying power consumption in
Table 10
. All power
states are specified. The temperature setting of 25
°
C is used for specifying the Deep Sleep Mode (DSM)
per the temperature range shown in
Table 7
.
Table 10
shows the power consumption for the i.MX27 device.

Switching duty cycles must be limited to a cumulative duration of 1 year or less (20% duty cycle for a 5 yr. rated part) to sustain
a MAX N
VDD
operating voltage of 3.3 V without significant device degradation. A switching cycle is defined as the period of
time that the pad is powered to N
VDD
and actively switching. Switching cycles exceeding this limit may affect device reliability
or cause permanent damage to the device. N
VDD
13 should not be shorted to other N
VDD
x supplies, if want to use the separate
power supply feature.
