5-3. ESD Ratings
5-4. Recommended Operating Conditions
Supply voltage noise should be less than 10mVpp. Excessive noise at the supply voltage will reduce
the RF performance.
Note: (1).VDD power supply recommended voltage : 2.7~3.3V
(2).When programming firm ware , the VDD supply voltage must in DC 2.4~3.3V,
To avoid programming has not completely, or abnormal status occur..
(3).For smaller coin cell batteries, with high worst-case end-of-life equivalent source resistance, a
22-μF VDDS input capacitor must be used to ensure compliance with this slew rate(6-6 timing req.).
