Reducing Current Consumption

28x DSPs incorporate a unique method to reduce the device current consumption. A reduction in current

consumption can be achieved by turning off the clock to any peripheral module which is not used in a

given application. Table 5-2 indicates the typical reduction in current consumption achieved by turning off

the clocks to various peripherals.

(1)

All peripheral clocks are disabled upon reset. Writing to/reading from peripheral registers is possible

only after the peripheral clocks are turned on.

(2)

Power savings can be achieved by powering down the flash. This must be done by code running off

RAM (not flash).

(3)

This number represents the current drawn by the digital portion of the ADC module. Turning off the

clock to the ADC module results in the elimination of the current drawn by the analog portion of the

ADC (IDDA) as well.
