2: Power
Power Supply
The host provides power to the AirPrime WP7610 through multiple power and ground
pins. The host must provide safe and continuous power at all times; the module does
not have an independent power supply, or protection circuits to guard against
electrical issues.
For detailed pinout and voltage/current requirements of this module, see the AirPrime
WP76XX Product Technical Specification.
Module Power States
The module has three main power states, as described in Tab le 2- 1.
Table 2-1: Supported Power States
State Description Wake-Up Events
OFF Module is off (no power to the system).
Apply power for system to go to Active state.
Apply power.
Interrupt Simple wakeup sources are configured to interrupt
from this power-saving state to the Active state.
An event generated from a state
change of RESET_IN_N or
POWER_ON_N, or a timeout event.
Active The module may be fully functioning (WWAN radio
and GNSS radio active), or be operating in airplane
mode (WWAN radio off).
Module actively reduces power consumption by
disabling components that are not in use (for example,
stepping down clock signals, putting USB bus into
selective suspend, etc.)
System wakes up (returns to fully
active mode) automatically as
required, or can be woken directly
via wakeable GPIOs.
