58.9.2.4 Power Consumption in ULP0, ULP1 and Idle Modes

  • Figures Typical Power Consumption in Idle Mode and Typical Power Consumption in ULP Mode 0 and ULP Mode 1 and Table 58-62, Table 58-63 and Table 58-64 report SAM9X60's average power consumption in Idle, ULP0 and ULP1 modes versus temperature measured on a few typical devices. They do not provide maximum power consumption specifications.
  • All power supply inputs are powered within their operating range and in particular VDDCORE = 1.15V.
  • There is no consumption on the device’s I/Os. To reach the best possible power consumption figures, it is of prime importance to set each I/O of the device to an appropriate state (pull-up/pull-down, etc.) with respect to the external components connected to these I/Os.
  • USB transceivers are disabled.
  • All peripheral clocks are disabled.
  • Current measurement is as per the following figure.

The following figures show the power consumption of the SAM9X60 in ULP0, ULP1 and Idle modes. These figures account for the current consumption in VDDCORE and VDDIN33: Power (mW) = IDDIN33 x 3.3V + IDDCORE x 1.15V with IDDIN33 and + IDDCORE as measured in the above table.

The following table gives the specification for ULP1 mode current consumption on VDDCORE and VDDIN33.

Table 58-65. Current Consumption in ULP1 Mode
Symbol Parameter Conditions Min Max Unit
IVDDCORE Current consumption in ULP1 mode (VDDCORE) VDDCORE = 1.15V – 14 mA
IVDDIN33 Current consumption in ULP1 mode (VDDIN33) VDDIN33 = 3.3V – 150 µA
