Table 64: Operating mode definition Mode Function Normal operation UMTS/LTE/5G Sleep UMTS/LTE/5G Idle UMTS/LTE/5G Talk UMTS/LTE/5G Standby UMTS/LTE/5G Data transmission Minimum functionality mode Flight mode Minimum power consumption mode Power off AT command AT+CSCLK=1 can be used to set the module to a sleep mode. In this case, the current consumption of module will be reduced to a very low level and the module can still receive paging message and SMS Software is active. Module is registered to the network, and ready to communicate Connection between two subscribers is in progress. In this case, the power consumption depends on network settings such as DTX off/on, FR/EFR/HR, hopping sequences, and antennas Module is ready for data transmission, but no data is currently sent or received. In this case, power consumption depends on network settings. There is data transmission in progress. In this case, power consumption is related to network settings (e.g., power control level);

uplink/downlink data rates, etc. AT command AT+CFUN=0 can be used to set the module to a minimum functionality mode without removing the power supply. In this mode, the RF part of the module will not work and the (U)SIM card will not be accessible, but USB port are still accessible. The power consumption in this mode is lower than normal mode AT command AT+CFUN=4 or pulling down the W_DISABLE1# pin can be used to set the module to flight mode without removing the power supply. In this case, the RF part of the module will not work, but the serial port and USB are still available. The power consumption is lower than normal mode In AT+CFUN=0 condition, send AT+CSCLK=1, minimum power consumption mode. Normally module will go into power off mode by sending the AT command AT+CPOF or pull down the FULL_CARD_POWER_OFF#

pin. In this mode the power management unit shuts down the power supply, and software is not active. The serial port and USB are not available the module enter 5.3.2 Sleep Mode In sleep mode, the current consumption of the module will be reduced to a very low level. Several hardware and software conditions must be satisfied in order to let module enter into sleep mode:

1. UART condition www.(U)SIMcom.com 84 SIM8380G-M2 Series Hardware Design V1.07 2. USB condition 3. Software condition NOTE 1. Before designing, pay attention to how to realize sleeping/waking function. 5.3.3 Minimum Functionality Mode and Flight Mode Minimum functionality mode ceases a majority of consumption. This mode is set by the AT command which provides a choice of 3 different functionality levels. in order to minimize the power the module, functions of AT+CFUN=0: Minimum functionality AT+CFUN=1: Full functionality (Default) AT+CFUN=4: Flight mode If module has been set to minimum functionality mode, the RF (U)SIM card functions will be closed while USB are still available. If module has been set to flight mode, the RF function will be closed while the (U)SIM card, the serial port and USB are still available. When module is in minimum functionality or flight mode, it can return to full functionality by the AT command AT+CFUN=1. www.(U)SIMcom.com 85 SIM8380G-M2 Series Hardware Design V1.07 5.4 Current Consumption The current consumptions are listed in the table below.

Module reserved a ground plane on the bottom side for the heat dissipating, customer could conduct the heat to the large board by the silica gel, for better thermal performance, customer could use a heat sink device to conduct the heat to the air. Figure 47: Thermal design diagram There are some design rules to enhance thermal dissipation performance:

Keep the module away from other heat sources such as battery, power, AP, etc. Make sure that the module mounting holes connect to the main PCB ground fully. Add enough through via on the main PCB. Via material is very important solid copper and stacked via is better. www.(U)SIMcom.com 93 SIM8380G-M2 Series Hardware Design V1.07 Make sure maximize airflow around the module. Recommend use heat dissipation material connect to the customers devices on the top side of the module to enhance the heat dissipation. Large thermal dissipation area is better. Chose a high effective heat dissipation material is better such as heat pipe, graphite sheets. The recommend thermal conductivity is 8w/m-k. NOTE 1. On customer main PCB, the size of exposed copper thermal dissipation area and exposed copper thermal dissipation area of module should be consistent, for more details, please refer to chapter2.3.

When module is mounted on the customers main board, the ESD components should be placed closed to the connectors which human body may touch, such as (U)SIM card holder, audio jacks, switches, USB interface, etc. The following table shows the module ESD test performance. In main PCB board, the post of screws and screws used to fix the M2 module should have good electrical conductivity and facilitate ESD release to better protect the module.
