Page 31: Operating Modes
Operating Modes W24 incorporates several operating modes. Each operating mode is different in the active features and interfaces. Table 2-1 summarizes the general characteristics of the W24 operating modes and provides general guidelines for operation. Mode VCC supply is disconnected. -
Page 32: Power Supply
Power Supply Power Supply The W24 power supply must be a single external DC voltage source of 3.3V to 4.2V. In order to support the stacked configuration, i.e. when G24 cellular module is coupled on the W24 module, the power supply must be able to sustain the required voltage level during a GSM transmit burst current surge, which may reach 2.0A. -
Page 33: Power Consumption
Figure 2-2: Transmission Power Drops Power Consumption Table 2-3 specifies typical W24 current consumption ratings in various operating modes. The current ratings refer to the overall W24 current consumption over the VCC supply. Parameter Description Powered off Powered off with... -
Page 34: Power On/Off Operation
When the W24 power supply is stable above the minimum operating level and W24 is powered off, all of its circuits are disabled. When W24 is turned on, by any of the methods described below, it will first perform an automatic initialization. When the initialization has completed, W24 resumes normal operation (stand alone mode), or turns on the G24 module (stacked modules) and resumes normal operation. -
Page 35: Turning The W24 On Using On_N
Turning the W24 On Using IGN The IGN input signal must be set low when not used. To turn on W24, this signal must be asserted high. The IGN signal must remain high for the duration of the W24 operation. W24 powers down when the IGN signal is returned to its low state. -
Page 36: Turning The W24 Off
The ON_N signal is internally pulled-up when power is applied to W24. Asserting the ON_N signal low for a minimum of 2 seconds will turn W24 off. This will initiate a normal power-off process, which includes G24 power down (stacked configuration) and disabling of all applications interfaces (UART, USB, etc.). -
Page 37: Turning The W24 Off Using Ign
Turning the W24 Off Using IGN The IGN signal may be used to power off W24 if the unit was powered-up by the IGN signal. When the IGN signal is set low, W24 will turn off. This will initiate a normal power-off process, which includes G24 power down (stacked configuration) and disabling of all applications interfaces (UART, USB, etc.). -
Page 38: Power Loss Shut Down
Power On/Off Operation Power Loss shut down A low power shut down occurs when W24 senses that the external power supply is below the minimal operating limit. The module will respond by powering down automatically without notice. This form of power-down is not recommended for regular use since the unexpected power loss may result in loss of data. -
Page 39: Low Power Mode
Deep Sleep Mode. Activating Low Power Mode By default, the W24 powers on in Idle mode. In this mode, all the W24 interfaces and features are functional and the module is fully active. Sleep mode is activated by setting the AT+iPSE>0. -
Page 40: Serial Interface During Low Power Mode
During low power mode the W24 serial interfaces are disabled. The W24 wakes up periodically from low power mode to monitor the network for data. After this short paging is completed, W24 returns to low power mode. During this short awake period, the serial interfaces are enabled and communications with the module is possible. -
Page 41: Wkupo_N Signal Operation
The WKUPO_N signal is an active-low W24 output that is asserted high by default. By asserting this signal low, the host can be waked up by W24. WKUPO_N alerts the host that W24 exits from Sleep mode into Idle mode due to network activity (see... -
Page 42: Permanent Termination Of Low Power Mode
AT+iPSE = 0 command can be received by W24. Deep Sleep Mode In case that W24 cannot locate an active access point or cannot register to it, W24 will enter the Deep Sleep Mode. During Deep Sleep Mode, network connection does not exist. W24 will periodically come out of the Deep Sleep Mode, to attempt to locate APs. -

The above signals are routed from 70-pin host connector to G24 70-pin connector via W24. They are not internally connected to W24 circuits. If the W24 will be used as stand alone only, the above pins should be left open. -
Page 49: Unused/Reserved Signals
Unused/Reserved Signals W24 provides an interface to unused and reserved G24 signals, to enable their usage in the future. The signals are directly routed from 70-pin host connector to the 70-pin cellular connector. The above pins should be left open. Here is the summary interface consists of the following pins (see... -
Page 50: Controls And Indicators Interface
W24 is operating. It is set low when W24 is powered off. When the RESET_N signal is low, the W24 interface signals are disabled and do not represent any valid data or state. Furthermore, any input signals connected to the W24 interface must be disabled (tri-state) or set low when RESET_N is low. -
