5.5.1 Reducing Current Consumption

280x devices have a richer peripheral mix compared to the 281x family. While the McBSP has been removed, the following new peripherals have been added on the 280x:

  • 3 SPI modules
  • 1 CAN module
  • 1 I2C module

The two event manager modules of the 281x have been enhanced and replaced with separate ePWM (6), eCAP (4) and eQEP (2) modules, providing tremendous flexibility in applications. Like 281x, 280x DSPs incorporate a unique method to reduce the device current consumption. Since 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 5-5 indicates the typical reduction in current consumption achieved by turning off the clocks.

Table 5-5 Typical Current Consumption by Various Peripherals (at 100 MHz)(1)

PERIPHERAL
MODULE		 IDD CURRENT
REDUCTION (mA)(2)
ADC 8(3)
I2C 5
eQEP 5
ePWM 5
eCAP 2
SCI 4
SPI 5
eCAN 11
(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) For peripherals with multiple instances, the current quoted is per module. For example, the 5 mA number quoted for ePWM is for one ePWM module.
(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 (IDDA18) as well.

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 110 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.
