Power pads characteristics

Note: Pad 1V8 is the reference voltage for IOs. It can be used to provide power small devices (100 mA

maximum usage). This voltage is not available when the modem is in Deep Sleep. When the modem

is in standby the voltage drops to 1.62 V as per Table 13.

See also section USIM Interfaces.

Note: Reference VBAT voltage range is 2.5 V to 5.5 V for RF-compliant operation and 2.2 V to 5.5 V for

functional behavior with possible degradation of RF performances.

Power-Up and Reset Sequences

Figure 4. Timing Diagram for Power-Up Sequence

Important:

The 1V8 power signal can remain low up to 370 μs after the VBAT rising edge.

Figure 5. Timing Diagram for Reset Sequence

Note: Since RESETN is pulled-up internally, RESETN does not need to be maintained low after VBAT is

established. This is shown by Figure 5. There is no timing condition between RESETN and VBAT.

Note: RESETN minimum duration for reliable detection is 100 µs.
