Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality

should not be assumed, damage may occur and reliability may be affected.

1. In some applications, VDDO can be higher than 2.1 V (maximum 3.3 V). In such cases, the user must set the VDDM voltage at a minimum

of 1.1 V

3. In order to be able to use a VBAT Min of 1.1 V, the  following reduced operating conditions for the RSL10 should be observed:

 Maximum Tx power 0 dBm.

 SYSCLK 

 24 MHz.

 Functional temperature range limited to 0

C

The following trimming parameters should be used: 

 VCC  = 1.10 V 

 VDDC = 0.92 V 

 VDDM = 1.05 V, will be limited by VCC at end of battery life

 VDDRF = 1.05 V, will be limited by VCC at end of battery life. VDDPA should be disabled 

RSL10 should enter in end

of

battery

life operating mode if VCC falls below 1.03 V. VCC will remain above 1.03 V if VBAT 

 1.10 V under

the restricted operating conditions described above.

4. Min VBAT = 1.05 V if RSL10 is disabled
