PRODUCTION DATA
The 2806x devices incorporate a method to reduce the device current consumption. Because each peripheral unit has an individual clock-enable bit, significant reduction in current consumption can be achieved by turning off the clock to any peripheral module that is not used in a given application. Furthermore, any one of the three low-power modes could be taken advantage of to reduce the current consumption even further. Table 7-1 indicates the typical reduction in current consumption achieved by turning off the clocks.

IDDIO current consumption is reduced by 15 mA (typical) when XCLKOUT is turned off.
The baseline IDD current (current when the core is executing a dummy loop with no peripherals enabled) is 40 mA, typical. To arrive at the IDD current for a given application, the current-drawn by the peripherals (enabled by that application) must be added to the baseline IDD current.
Following are other methods to reduce power consumption further:
