7.5.2 Reducing Current Consumption

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.

(1) All peripheral clocks (except CPU Timer clock) are disabled upon reset. Writing to or reading from peripheral registers is possible only after the peripheral clocks are turned on.
(2) 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.
(3) For peripherals with multiple instances, the current quoted is per module. For example, the 2 mA value quoted for ePWM is for one ePWM module.
Note:

IDDIO current consumption is reduced by 15 mA (typical) when XCLKOUT is turned off.

Note:

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:

  • The flash module may be powered down if code is run off SARAM. This results in a current reduction of 18 mA (typical) in the VDD rail and 13 mA (typical) in the VDDIO rail.
  • Savings in IDDIO may be realized by disabling the pullups on pins that assume an output function.
  • To realize the lowest VDDA current consumption in a low-power mode, see the respective analog chapter of the TMS320x2806x Technical Reference Manual to ensure each module is powered down as well.
  • Power savings can be achieved by powering down the flash. This must be done by code running off RAM (not flash).
