Specifications
3.1 Electrical Characteristics
3.1.1 Absolute Maximum Ratings
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.
3.1.2 Test Conditions
Notes: 1. The parameters are measured under the following conditions:
a) BitCloud Software is running at 4 MHz clock rate, DTR line management is turned off
b) All interfaces are set to the default state (see Pin Assignment Table)
c) Output TX power is 0 dBm
d) JTAG is not connected
2. Supply voltage below 2.7V requires the MCU to be operating at 2 MHz speed
