2.1.2.1 Absolute Maximum Ratings
The absolute maximum ratings stated in Table 4 are stress ratings under any conditions.
Stresses beyond any of these limits will cause permanent damage to TX62/TX82.
Table 4: Absolute maximum ratings
Parameter Min Max Unit
Supply voltage BATT+
BB
(no service) -0.5 +6.0 V
Supply voltage BATT+
RF
(TX82-W only; no service) -0.5 +6.0 V
Voltage at all digital lines in Power Down mode -0.5 +0.5 V
Voltage at digital lines 1.8V domain in normal operation

1. A maximum rating of 1.95V (for V
IH
max) is recommended for all digital lines. Exceeding this value how-
ever will not necessarily harm the module as long as the rating remains below the absolute maximum
rating of 1.95+0.14V, but it will decrease the safety margin in case of short spikes or ripple.
-0.3 +2.09 V
Current at digital lines in normal operation -5 +5 mA
Voltage at SIM interface, CCVCC 1.8V in normal operation -0.3 +2.0 V
Current at SIM interface in normal 1.8V operation - -600 mA
Voltage at ADC line in normal operation -0.5 +1.910 V
V180 in normal operation -0.3 +2.09 V
Current at V180 in normal operation - -600 mA
VCORE in normal operation +0.5 +1.304 V
Current at VCORE in normal operation - -1200 mA
Voltage at USB lines -0.5 5.75 V
