SIM interface The M18Q2 includes a SIM controller, interface pins, and a dedicated LDO (3.0 V or 1.8 V). The following figures describe the additional logic connection between the M18Q2 and the SIM card. User Manual Figure 5. SIM card circuit (example) 2.7. Control interface (wakeup) In applications where power consumption is a major factor in performance metrics (such as battery-operated sensors that are based on IOT/M2M modem solution and also include a third party host), it is necessary to define a simple interface that will allow both the modem and the host to be able to enter low power states whenever possible and the other side to wake it up once required. For example, if the host has no data to transmit nor any other tasks, it may enter some low power state according to its own capabilities and configurations. If during that period the host is in a low power state and the modem suddenly receives data, it must wake-up the host. A similar requirement exists from the other side. For example, if the modem is in a low power state and suddenly the host must transmit data, it must be able to wake-up the modem. The interface consists of two signals: One is driven by the host and received by the modem; the other is driven by the modem and received by the host. Each side can wake the other side by toggling wakeup signal high and allowing the other side to go to Normal Internal Use Confidential Restricted Confidential 17 / 33 User Manual sleep when not needed by toggling it low. WAKEUP_IN (Host: Output, Modem: Input):

LOW: SoC does not require the MODEM (allowing it to sleep). HIGH: SoC requires the MODEM or acknowledges it is ready following a wakeup request from the MODEM. WAKEUP_OUT (Host: Input, Modem: Output):

LOW: The MODEM does not require the Host (allowing it to sleep) HIGH: The MODEM requires the Host or acknowledges it is ready following a wakeup request from the SoC. 2.8.

Antenna Guidance The antenna should be 50ohm characteristic impedance with the return loss of better than -10dB at the operation band. The antenna gain would affect the radiated power and regulator test result. 3.4. Interference and sensitivity This section includes tips to assist developers in identifying the interference that may affect the M18Q2 when is it used in systems. Interference from other wireless devices Harmonics, inter-modulated signal generated from wireless devices that fall in RX ranges of the M18Q2, may result in degraded RX performance. It is highly recommended to check RX performance of entire systems within the shielding environment. Interference from host interface High-speed signal-switching elements in systems can easily couple noise into the module

(Ex.: DDR memory, LCD modules, DC-DC converter). Methods to avoid sources of interference Normal Internal Use Confidential Restricted Confidential 24 / 33 Connector to Antenna User Manual Antenna location is important; we recommend directing the antenna away from high-speed switching signals. Furthermore, the trace from the module to the antenna should be as short as possible and must be shielded by complete grounding. The M18Q2 is well shielded; the high-speed elements on a system should have shielding reserved during the early stages of development. 3.5. Radiated sensitivity measurement Over-the-air testing can demonstrate the TRX ability of the whole system. Keys elements that affect the measurement are:

SIM interface The M14Q2F includes a SIM controller, interface pins, and a dedicated LDO (3.0 V or 1.8 V). The following figures describe the additional logic connection between the M14Q2F and the SIM card. User Manual Figure 5. SIM card circuit (example) 2.7. Control interface (wakeup) In applications where power consumption is a major factor in performance metrics (such as battery-operated sensors that are based on IOT/M2M modem solution and also include a third party host), it is necessary to define a simple interface that will allow both the modem and the host to be able to enter low power states whenever possible and the other side to wake it up once required. For example, if the host has no data to transmit nor any other tasks, it may enter some low power state according to its own capabilities and configurations. If during that period the host is in a low power state and the modem suddenly receives data, it must wake-up the host. A similar requirement exists from the other side. For example, if the modem is in a low power state and suddenly the host must transmit data, it must be able to wake-up the modem. The interface consists of two signals: One is driven by the host and received by the modem; the other is driven by the modem and received by the host. Each side can wake the other side by toggling wakeup signal high and allowing the other side to go to Normal Internal Use Confidential Restricted Confidential 17 / 33 User Manual sleep when not needed by toggling it low. WAKEUP_IN (Host: Output, Modem: Input):

LOW: SoC does not require the MODEM (allowing it to sleep). HIGH: SoC requires the MODEM or acknowledges it is ready following a wakeup request from the MODEM. WAKEUP_OUT (Host: Input, Modem: Output):

LOW: The MODEM does not require the Host (allowing it to sleep) HIGH: The MODEM requires the Host or acknowledges it is ready following a wakeup request from the SoC. 2.8.

Antenna Guidance The antenna should be 50ohm characteristic impedance with the return loss of better than -10dB at the operation band. The antenna gain would affect the radiated power and regulator test result. 3.4. Interference and sensitivity This section includes tips to assist developers in identifying the interference that may affect the M14Q2F when is it used in systems. Interference from other wireless devices Harmonics, inter-modulated signal generated from wireless devices that fall in RX ranges of the M14Q2F, may result in degraded RX performance. It is highly recommended to check RX performance of entire systems within the shielding environment. Interference from host interface High-speed signal-switching elements in systems can easily couple noise into the module

(Ex.: DDR memory, LCD modules, DC-DC converter). Methods to avoid sources of interference Normal Internal Use Confidential Restricted Confidential 24 / 33 Connector to Antenna User Manual Antenna location is important; we recommend directing the antenna away from high-speed switching signals. Furthermore, the trace from the module to the antenna should be as short as possible and must be shielded by complete grounding. The M14Q2F is well shielded; the high-speed elements on a system should have shielding reserved during the early stages of development. 3.5. Radiated sensitivity measurement Over-the-air testing can demonstrate the TRX ability of the whole system. Keys elements that affect the measurement are:

SIM interface The M14Q2FG includes a SIM controller, interface pins, and a dedicated LDO (3.0 V or 1.8 V). The following figures describe the additional logic connection between the M14Q2FG and the SIM card. User Manual Figure 5. SIM card circuit (example) 2.7. Control interface (wakeup) In applications where power consumption is a major factor in performance metrics (such as battery-operated sensors that are based on IOT/M2M modem solution and also include a third party host), it is necessary to define a simple interface that will allow both the modem and the host to be able to enter low power states whenever possible and the other side to wake it up once required. For example, if the host has no data to transmit nor any other tasks, it may enter some low power state according to its own capabilities and configurations. If during that period the host is in a low power state and the modem suddenly receives data, it must wake-up the host. A similar requirement exists from the other side. For example, if the modem is in a low power state and suddenly the host must transmit data, it must be able to wake-up the modem. The interface consists of two signals: One is driven by the host and received by the modem; the other is driven by the modem and received by the host. Each side can wake the other side by toggling wakeup signal high and allowing the other side to go to Normal Internal Use Confidential Restricted Confidential 17 / 33 User Manual sleep when not needed by toggling it low. WAKEUP_IN (Host: Output, Modem: Input):

LOW: SoC does not require the MODEM (allowing it to sleep). HIGH: SoC requires the MODEM or acknowledges it is ready following a wakeup request from the MODEM. WAKEUP_OUT (Host: Input, Modem: Output):

LOW: The MODEM does not require the Host (allowing it to sleep) HIGH: The MODEM requires the Host or acknowledges it is ready following a wakeup request from the SoC. 2.8.

Antenna Guidance The antenna should be 50ohm characteristic impedance with the return loss of better than -10dB at the operation band. The antenna gain would affect the radiated power and regulator test result. 3.4. Interference and sensitivity This section includes tips to assist developers in identifying the interference that may affect the M14Q2FG when is it used in systems. Interference from other wireless devices Harmonics, inter-modulated signal generated from wireless devices that fall in RX ranges of the M14Q2FG, may result in degraded RX performance. It is highly recommended to check RX performance of entire systems within the shielding environment. Interference from host interface High-speed signal-switching elements in systems can easily couple noise into the module

(Ex.: DDR memory, LCD modules, DC-DC converter). Methods to avoid sources of interference Normal Internal Use Confidential Restricted Confidential 24 / 33 Connector to Antenna User Manual Antenna location is important; we recommend directing the antenna away from high-speed switching signals. Furthermore, the trace from the module to the antenna should be as short as possible and must be shielded by complete grounding. The M14Q2FG is well shielded; the high-speed elements on a system should have shielding reserved during the early stages of development. 3.5. Radiated sensitivity measurement Over-the-air testing can demonstrate the TRX ability of the whole system. Keys elements that affect the measurement are:

SIM interface The M14Q2 includes a SIM controller, interface pins, and a dedicated LDO (3.0 V or 1.8 V). The following figures describe the additional logic connection between the M14Q2 and the SIM card. User Manual Figure 5. SIM card circuit (example) 2.7. Control interface (wakeup) In applications where power consumption is a major factor in performance metrics (such as battery-operated sensors that are based on IOT/M2M modem solution and also include a third party host), it is necessary to define a simple interface that will allow both the modem and the host to be able to enter low power states whenever possible and the other side to wake it up once required. For example, if the host has no data to transmit nor any other tasks, it may enter some low power state according to its own capabilities and configurations. If during that period the host is in a low power state and the modem suddenly receives data, it must wake-up the host. A similar requirement exists from the other side. For example, if the modem is in a low power state and suddenly the host must transmit data, it must be able to wake-up the modem. The interface consists of two signals: One is driven by the host and received by the modem; the other is driven by the modem and received by the host. Each side can wake the other side by toggling wakeup signal high and allowing the other side to go to Normal Internal Use Confidential Restricted Confidential 17 / 33 User Manual sleep when not needed by toggling it low. WAKEUP_IN (Host: Output, Modem: Input):

LOW: SoC does not require the MODEM (allowing it to sleep). HIGH: SoC requires the MODEM or acknowledges it is ready following a wakeup request from the MODEM. WAKEUP_OUT (Host: Input, Modem: Output):

LOW: The MODEM does not require the Host (allowing it to sleep) HIGH: The MODEM requires the Host or acknowledges it is ready following a wakeup request from the SoC. 2.8.

Antenna Guidance The antenna should be 50ohm characteristic impedance with the return loss of better than -10dB at the operation band. The antenna gain would affect the radiated power and regulator test result. 3.4. Interference and sensitivity This section includes tips to assist developers in identifying the interference that may affect the M14Q2 when is it used in systems. Interference from other wireless devices Harmonics, inter-modulated signal generated from wireless devices that fall in RX ranges of the M14Q2, may result in degraded RX performance. It is highly recommended to check RX performance of entire systems within the shielding environment. Interference from host interface High-speed signal-switching elements in systems can easily couple noise into the module

(Ex.: DDR memory, LCD modules, DC-DC converter). Methods to avoid sources of interference Normal Internal Use Confidential Restricted Confidential 24 / 33 Connector to Antenna User Manual Antenna location is important; we recommend directing the antenna away from high-speed switching signals. Furthermore, the trace from the module to the antenna should be as short as possible and must be shielded by complete grounding. The M14Q2 is well shielded; the high-speed elements on a system should have shielding reserved during the early stages of development. 3.5. Radiated sensitivity measurement Over-the-air testing can demonstrate the TRX ability of the whole system. Keys elements that affect the measurement are:

SIM interface The M14Q2G includes a SIM controller, interface pins, and a dedicated LDO (3.0 V or 1.8 V). The following figures describe the additional logic connection between the M14Q2G and the SIM card. User Manual Figure 5. SIM card circuit (example) 2.7. Control interface (wakeup) In applications where power consumption is a major factor in performance metrics (such as battery-operated sensors that are based on IOT/M2M modem solution and also include a third party host), it is necessary to define a simple interface that will allow both the modem and the host to be able to enter low power states whenever possible and the other side to wake it up once required. For example, if the host has no data to transmit nor any other tasks, it may enter some low power state according to its own capabilities and configurations. If during that period the host is in a low power state and the modem suddenly receives data, it must wake-up the host. A similar requirement exists from the other side. For example, if the modem is in a low power state and suddenly the host must transmit data, it must be able to wake-up the modem. The interface consists of two signals: One is driven by the host and received by the modem; the other is driven by the modem and received by the host. Each side can wake the other side by toggling wakeup signal high and allowing the other side to go to Normal Internal Use Confidential Restricted Confidential 17 / 33 User Manual sleep when not needed by toggling it low. WAKEUP_IN (Host: Output, Modem: Input):

LOW: SoC does not require the MODEM (allowing it to sleep). HIGH: SoC requires the MODEM or acknowledges it is ready following a wakeup request from the MODEM. WAKEUP_OUT (Host: Input, Modem: Output):

LOW: The MODEM does not require the Host (allowing it to sleep) HIGH: The MODEM requires the Host or acknowledges it is ready following a wakeup request from the SoC. 2.8.

Antenna Guidance The antenna should be 50ohm characteristic impedance with the return loss of better than -10dB at the operation band. The antenna gain would affect the radiated power and regulator test result. 3.4. Interference and sensitivity This section includes tips to assist developers in identifying the interference that may affect the M14Q2G when is it used in systems. Interference from other wireless devices Harmonics, inter-modulated signal generated from wireless devices that fall in RX ranges of the M14Q2G, may result in degraded RX performance. It is highly recommended to check RX performance of entire systems within the shielding environment. Interference from host interface High-speed signal-switching elements in systems can easily couple noise into the module

(Ex.: DDR memory, LCD modules, DC-DC converter). Methods to avoid sources of interference Normal Internal Use Confidential Restricted Confidential 24 / 33 Connector to Antenna User Manual Antenna location is important; we recommend directing the antenna away from high-speed switching signals. Furthermore, the trace from the module to the antenna should be as short as possible and must be shielded by complete grounding. The M14Q2G is well shielded; the high-speed elements on a system should have shielding reserved during the early stages of development. 3.5. Radiated sensitivity measurement Over-the-air testing can demonstrate the TRX ability of the whole system. Keys elements that affect the measurement are:

SIM interface The M14Q2 includes a SIM controller, interface pins, and a dedicated LDO (3.0 V or 1.8 V). The following figures describe the additional logic connection between the M14Q2 and the SIM card. User Manual Figure 5. SIM card circuit (example) 2.7. Control interface (wakeup) In applications where power consumption is a major factor in performance metrics (such as battery-operated sensors that are based on IOT/M2M modem solution and also include a third party host), it is necessary to define a simple interface that will allow both the modem and the host to be able to enter low power states whenever possible and the other side to wake it up once required. For example, if the host has no data to transmit nor any other tasks, it may enter some low power state according to its own capabilities and configurations. If during that period the host is in a low power state and the modem suddenly receives data, it must wake-up the host. A similar requirement exists from the other side. For example, if the modem is in a low power state and suddenly the host must transmit data, it must be able to wake-up the modem. The interface consists of two signals: One is driven by the host and received by the modem; the other is driven by the modem and received by the host. Each side can wake the other side by toggling wakeup signal high and allowing the other side to go to Normal Internal Use Confidential Restricted Confidential 17 / 33 User Manual sleep when not needed by toggling it low. WAKEUP_IN (Host: Output, Modem: Input):

LOW: SoC does not require the MODEM (allowing it to sleep). HIGH: SoC requires the MODEM or acknowledges it is ready following a wakeup request from the MODEM. WAKEUP_OUT (Host: Input, Modem: Output):

LOW: The MODEM does not require the Host (allowing it to sleep) HIGH: The MODEM requires the Host or acknowledges it is ready following a wakeup request from the SoC. 2.8.

Antenna Guidance The antenna should be 50ohm characteristic impedance with the return loss of better than -10dB at the operation band. The antenna gain would affect the radiated power and regulator test result. 3.4. Interference and sensitivity This section includes tips to assist developers in identifying the interference that may affect the M14Q2 when is it used in systems. Interference from other wireless devices Harmonics, inter-modulated signal generated from wireless devices that fall in RX ranges of the M14Q2, may result in degraded RX performance. It is highly recommended to check RX performance of entire systems within the shielding environment. Interference from host interface High-speed signal-switching elements in systems can easily couple noise into the module

(Ex.: DDR memory, LCD modules, DC-DC converter). Methods to avoid sources of interference Normal Internal Use Confidential Restricted Confidential 24 / 33 Connector to Antenna User Manual Antenna location is important; we recommend directing the antenna away from high-speed switching signals. Furthermore, the trace from the module to the antenna should be as short as possible and must be shielded by complete grounding. The M14Q2 is well shielded; the high-speed elements on a system should have shielding reserved during the early stages of development. 3.5. Radiated sensitivity measurement Over-the-air testing can demonstrate the TRX ability of the whole system. Keys elements that affect the measurement are:
