ME310G1 Hardware Design Guide POWER SUPPLY The power supply circuitry and the board layout are a very important part in the full product design and they strongly reflect on the overall performance of the product so the requirements and the guidelines that will follow should be read carefully for a proper design.
ME310G1 Hardware Design Guide Note: The application’s power supply section must be designed with care to avoid an excessive voltage drop during transmission peak current absorptions. If the voltage drops beyond the limits of the Extended Operating Voltage range, an unintentional module power off can occur.

ME310G1 Hardware Design Guide used. A switching power supply will not be suited due to the low drop out requirements. • When using a linear regulator, a proper heat sink shall be provided in order to dissipate the power generated. •...
ME310G1 Hardware Design Guide • In any case the frequency and Switching design selection is related to the application to be developed since the switching frequency could also generate EMC interferences. • For car PB battery the input voltage can rise up to 15,8V and this should be kept in mind when choosing components: all components in the power supply must withstand this voltage.
Page 30
ME310G1 Hardware Design Guide • A protection diode should be inserted close to the power input, in order to save the ME310G1 from power polarity inversion. Otherwise the battery connector should be done in a way to avoid polarity inversions when connecting the battery. •...
ME310G1 Hardware Design Guide Thermal Design Guidelines Worst case as reference values for thermal design of ME310G1 are: • Average current consumption: 700 mA (LTE CAT M1 and NB1 modes) • Average current consumption: 700 mA (GPRS and EDGE modes) •...
ME310G1 Hardware Design Guide • A dedicated ground for the Switching regulator separated by the common ground plane is suggested. • The placement of the power supply on the board should be done in such a way to guarantee that the high current return paths in the ground plane are not overlapped to any noise sensitive circuitry as the microphone amplifier/buffer or earphone amplifier.

ME310G1 Hardware Design Guide Item Typical Output voltage 1.35V 1.8V 1.8V Output current Table 17: Operating range characteristics of PWRMON signal Note: PWRMON during PSM period is LOW ( PSM has to be previously enabled by AT+CPSMS command) Note: The Output Current MUST never be exceeded; care must be taken when designing the application section to avoid an excessive current consumption.
ME310G1 Hardware Design Guide DIGITAL SECTION ME310G1 has four main operation states: • OFF state: Vbatt is applied and only RTC is running. The Baseband is switched OFF and the only possible change is the ON state. • ON state: the baseband is fully switched on and ME310G1 is ready to accept AT commands.
ME310G1 Hardware Design Guide Power On The following flow chart shows the proper “Modem Turn ON” procedure. “Modem ON Proc” START VBATT>VBATT PWRMON=ON ? ON_OFF* = LOW Delay = 5 sec ON_OFF*= HIGH PWRMON=ON ? Delay = 1 sec GO TO “Start AT Commands””...
ME310G1 Hardware Design Guide In some use cases ON_OFF* can be tied fix LOW taking in account two limitations: 1. PSM wake-up asynchronous capability will be lost. 2. To perform an unconditional shutdown it is necessary to send AT#SYSHALT command and then cut Vbatt. Power Off The proper procedure to power-off the module is to use the AT#SHDN command.
ME310G1 Hardware Design Guide Unconditional shutdown The following flow chart shows the proper procedure for unconditional shutdown of ME310G1 except in PSM mode. When the procedure is completed the ME310G1 is reset and it stops any operation. After the release of the line, the ME310G1 is unconditionally shut down, without performing any detach operation from the network in which it is registered.
ME310G1 Hardware Design Guide Warning: Unconditional Hardware SHUTDOWN by toggling VBATT Power, must not be used during the normal shutdown operation of the device since it does not detach the device from the network and can damage the memory content. It shall be kept as an emergency exit procedure.
ME310G1 Hardware Design Guide Fast shut down by hardware The Fast Power Down can be triggered by configuration of any GPIO. HI level to LOW level transition of GPIO triggers fast power down procedure. Example circuit: Note: Consider voltage drop under max current conditions when defining the voltage detector thereshold in order to avoid unwanted shutdown.

It differs from the PC-RS232 in the signal polarity (RS232 is reversed) and levels. Warning: C104/RXD1 cannot have any PU or HIGH state during BOOTING UP phase.
ME310G1 Hardware Design Guide General purpose I/O The ME310G1 module is provided by a set of Configurable Digital Input / Output pins (CMOS 1.8V). Input pads can only be read; they report the digital value (high or low) present on the pad at the read time of. The Output pads can only be written or queried and set the value of the pad output.
