3.3. Operating modes

The following table summarizes the various operating modes, each operating modes is referred to in the following chapters.

Table 2：Overview of operating modes

Mode Function

Normal operation

GSM/GPRS Sleep

Module will automatically go into Sleep mode if there is no air link activation and no hardware interrupt (such as GPIO interrupt or data on serial port). In this case, the current consumption of module will reduce to the minim. During sleep mode, the module can still receive paging message.

GSM IDLE Module has registered to the GSM network, and the

module is ready to send and receive.

GSM TALK CSD connection is going on between two subscribers. In

this case, the power consumption depends on network condition and settings such as DTX off/on, FR/EFR/HR, hopping sequences.

GPRS IDLE Module is ready for GPRS data transfer, but no data is

currently sent or received. In this case, power consumption depends on network settings and GPRS configuration (e.g. multi-slot settings).

GPRS

DATA

There is GPRS data in transfer (PPP or TCP or UDP). In this case, power consumption is related with network settings (e.g. power control level), uplink / downlink data rates and GPRS configuration (e.g. used multi-slot

settings). POWER DOWN

The power management ASIC disconnects the power supply from the base band part of the module, only the power supply for the RTC is remained. Software is not active. The serial interfaces are not accessible.

Alarm mode

RTC alert function launches this restricted operation while the module is in POWER DOWN mode. V3338 will not be registered to GSM network and only parts of AT commands can be available.

3.4. Power supply

The power supply must be able to provide sufficient current up to 2A.

For the VBAT input, a local bypass capacitor is recommended. A capacitor (above 100µF, low ESR) is recommended. Multi-layer ceramic chip (MLCC) capacitors can provide the best combination of low ESR and small size but may not be cost effective. A lower cost choice may be a 100 µF tantalum capacitor (low ESR) with a small (1 µF to 10µF) ceramic in parallel, which is illustrated as following figure. And the capacitors should put as closer as possible to the V3338 VBAT (RF) pins. A voltage regulator diode should been add between the Vbat and Gnd, and the BZV55C5V1 of Philips could been used. The following figure is the recommended circuit.

Minimizing power losses

Please pay special attention to the supply power when you are designing your applications. Please make sure that the input voltage will never drops below 3.3V even in a transmit burst during which the current consumption may rise up to 2A. If the power voltage drops below 3.3V, the module may be switched off. You should also take the resistance of the power supply lines on the host board or of battery pack into account.

3.5. Power up and power down scenarios

3.5.1. Turn on V3338

MD231 can be turned on by following two ways:

z Via PWRKEY pin: You can turn on the V3338 to normal operating mode by driving

the PWRKEY to a low level voltage for 1500ms;

z Via RTC interrupt: starts ALARM modes; z For some application system, we can connect the “PWRKEY” to “GND” so that the

module will be turn on as soon as the 3.8V power supply to the module. But, if “PWRKEY” linked to “GND”, other keypad pin could not work. Here is a circuit to make the module power on automatically. GPIO26 is the pin78 of the V3338. If the module power on, the GPIO26 will output high level, on consequence, the “PWR_KEY” will be high level so that other keypad pin could work.

3.5.2. Turn off V3338

V3338 can be truned off by following two ways:

Driving the PWRKEY to a low level for 1500ms when module working

z z

Use “AT + CKPD=”P”, 50” command to turn off V3338 module.

3.5.3. System reset for V3338

You can reset V3338 by driving the “system reset” pin to a low level voltage for 500ms. If V3338 blocked in hardware or software, you can not turn off V3338 by “PWRKEY” pin or by AT command, the only way is driving the “System reset” pin to low level for more than 1s and then high level. The module will reset.

3.5.4. Power saving

3.6. Serial interfaces

V3338 provides

UARTs provide full duplex serial communication channels between the module and external devices. Serial Port can be used for CSD FAX, GPRS service and send AT command of controlling module. Serial port supports the communication rate as following: 1200, 2400, 4800, 9600 (Default), 19200, 38400, 57600, 115200 The serial port The follow table is the pin definition of UART.
