Notes: 1. Absolute Maximum Ratings are the values beyond which damage to the device may occur. Under no
circumstances must the absolute maximum ratings given in this table be violated. Stresses beyond those listed
under "Absolute Maximum Ratings" may cause permanent damage to the device.
This is a stress rating only. Functional operation of the device at these or other conditions, beyond those indicated
in the operational sections of this specification, is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
2. Attention! ZigBit is an ESD-sensitive device. Precaution should be taken when handling the device in order to
prevent permanent damage.

Note 1: Output TX power (when measuring consumption in TX mode) is +9 dBm.
Note 2:
a) All interfaces are set to the default state (see Pin Assignment Table).
b) JTAG is not connected.
c) CPU Clock configured when doing this measurement – 16MHz for all modes except Power save and Power down
modes
Current consumption depends on multiple factors, including but not limited to, the board design and materials, Protocol settings,
network activity, EEPROM read/write operations. It also depends on MCU load and/or peripherals used by an application.
