L70 Hardware Design
L70_HD_V1.0 - 28 -
* This figure can be used to determine the maximum current capability of power supply.
Note: Operation beyond the "Operating Conditions" is not recommended and extended exposure
beyond the "Operating Conditions" may affect device reliability.
5.3. Current consumption
The values for current consumption are shown in Table 14.
Table 14: The module current consumption (passive antenna)
Note: In the standby mode, the power supply to active antenna through VCC_RF is cut off. It will
be re-activated when the module exits from the standby mode.
5.4. Electro-static discharge
L70 module is an ESD sensitive device. ESD protection precautions should still be emphasized.
Proper ESD handing and packaging procedures must be applied throughout the processing, handing
and operation of any application.
The ESD bearing capability of the module is listed in Table 15. Note that the customer should add
ESD components to module pins in the particular application except RF_IN, VCC and GND pins.
