6.3 Low power operation
CC2430DB is designed for low power operation when running from batteries. Only the
CC2430 is powered in this mode, the USB MCU is not powered. The voltage to the peripheral
functions connected to the CC2430 is controlled by an I/O pin P1.2 (VDD_SW_CTRL) on the
CC2430. Table 4 lists the current consumption for each of the peripherals.
To obtain minimum current consumption with the CC2430DB, the VDD_SW_CTRL (P1.2)
output must be configured as output.

Table 4 below shows the current consumption for all modules and operation modes with 3.3V
