If the VBAT power supply is already stable before starting up the module, the delay time can be ignored. 3.3.2 Module Shutdown The L816-AM module can be shut down by software or hardware control. Control mode Software Hardware Action Condition Sending AT+CPWROFF command Pull down Power_On/Off pin Normal shutdown. Only used when a hardware exception occurs and the software control cannot be used. The module can be shut down by sending AT+CPWROFF command. When the module receives the shutdown command, the module will plug Low the FW_Ready and start the finalization process (the reverse process of initialization), and it will be completed after 3s. In the finalization process, the module will save the network, SIM card and some other parameters from memory, then clear the memory and PMU will be powered off. The control timing is shown in Figure 3-7: Figure 3-7 Software Shutdown Timing Control After the software shutdown, the Power_On/Off pin will remain high which prevents the module from restarting again. To enable the next restart, the Power_On/Off pin should be pulled low after shutting down. Reproduction forbidden without Fibocom Wireless Inc. written authorization - All Rights Reserved. L816-AM Hardware User Manual Page 24 of 42 3.3.3 Module Reset The L816-AM module can reset to its initial status by pulling down the Reset_N signal for more than 10ms (100ms is recommended), and the module will restart after the Reset_N signal is released. When the customer executes Reset_N function, the PMU remains its power inside the module. The recommended circuit design is shown in the Figure 3-8: Figure 3-8 Recommended Design for Reset Circuit The reset control timing is shown in Figure 3-9: Figure 3-9 Reset Timing Control Note: Reset_N is a sensitive signal, it’s recommended to add a filter capacitor close to the module. In case of PCB layout, the Reset_N signal lines should keep away from the RF interference and protected by GND. Also, the Reset_N signal lines shall neither near the PCB edge nor route on the surface planes to avoid module from reset caused by ESD problems.

Since the speed of the Modem COM port is not sufficient for the 150 Mbps peak downlink speed requirement for LTE, so it is not recommended to be used. 3.4.2 USB Interface Application The reference circuit is shown in Figure 3-10: Figure 3-10 Reference Circuit for USB Interface Reproduction forbidden without Fibocom Wireless Inc. written authorization - All Rights Reserved. L816-AM Hardware User Manual Page 26 of 42 Since the module supports USB 2.0 High-Speed, it is required to use TVS diodes with equivalent capacitance of 1pF or smaller ones on the USB_DN/DP differential signal lines, it is recommended to use 0.5pF TVS diodes. There is no special requirement for TVS diodes on VBUS pin, normally the 8 ~ 10pF TVS diodes can be used. USB_DN and USB_DP are high speed differential signal lines with the maximum transfer rate of 480 Mbit/s, so the following rules shall be followed carefully in the case of PCB layout: USB_DN and USB_DP signal lines should have the differential impedance of 90 ohms. USB_DN and USB_DP signal lines should be parallel and have the equal length, the right angle routing should be avoided. USB_DN and USB_DP signal lines should be routed on the layer that is next to the ground layer, and be wrapped with GND on both sides and layers. 3.5 USIM Interface The L816-AM module has a built-in USIM card interface, which supports 1.8V and 3V SIM cards. 3.5.1 USIM Pins The USIM pins are described as follows: Pin Pin Name I/O 20 VSIM1 PO 18 SIM1_RST 19 SIM1_CLK 17 SIM1_DATA Reset Value Pin Description Type USIM power supply 1.8V/3V USIM reset 1.8V/3V USIM clock 1.8V/3V I/O USIM data with internal 4.7KΩ pull-up 1.8V/3V USIM card detection with 390KΩ pull up. 26 SIM1_CD Active-high, and high level means SIM 1.8V card is inserted; and low level means SIM card is detached.

SIM Card Slot Reproduction forbidden without Fibocom Wireless Inc. written authorization - All Rights Reserved. L816-AM Hardware User Manual Page 28 of 42 The principles for N.O. SIM card slot design are described as follows: When the SIM card is detached, it connects an open circuit between CD and SW pins, and drives the SIM1_CD pin low. When the SIM card is inserted, it connects the short circuit between CD and SW pins, and drives the SIM1_CD pin high. Suggested SIM1_CD pin increase TVS to protect the pin. 3.5.3 USIM Hot-Plugging The L816-AM module supports the SIM card hot-plugging detection function, which determines whether the SIM card is inserted or detached by detecting the SIM1_CD pin state of the SIM card slot. The SIM card hot-plugging detection function can be configured by “AT+MSMPD” command, and the description for AT command is as follows: AT Command Hot-plugging Detection Function Description Default value, the SIM card hot-plugging detection AT+MSMPD=1 Enable function is enabled. The module can detect whether the SIM card is inserted or not through the SIM1_CD pin state. The SIM card hot-plugging detection function is disabled. AT+MSMPD=0 Disable The module reads the SIM card when starting up, and the SIM1_CD status will not be detected. After the SIM card hot-plugging detection function is enabled, the module detects that the SIM card is inserted when the SIM1_CD pin is high, then executes the initialization program and finish the network registration after reading the SIM card information. When the SIM1_CD pin is low, the module determines that the SIM card is detached and does not read the SIM card. Note: By default, SIM1_CD is active-high, which can be switched to active-low by the AT command. Please refer to the AT Commands Manual for the AT command.

L816-AM Hardware User Manual Page 29 of 42 3.5.4 USIM Design The SIM card circuit design shall meet the EMC standards and ESD requirements with the improved capability to resist interference, to ensure that the SIM card can work stably. The following guidelines should be noted in case of design: The SIM card slot placement should near the module as close as possible, and away from the RF antenna, DC/DC power supply, clock signal lines, and other strong interference sources. The SIM card slot with a metal shielding housing can improve the anti-interference ability. The trace length between the SIM card slot and the module should not exceed 100mm, or it could reduce the signal quality. The SIM1_CLK and SIM1_DATA signal lines should be isolated by GND to avoid crosstalk interference. If it is difficult for the layout, the whole SIM signal lines should be wrapped with GND as a group at least. The filter capacitors and ESD devices for SIM card signals should be placed near to the SIM card slot, and the ESD devices with 22~33pF capacitance should be used. 3.6 GPIO The L816-AM module provides four signals to indicate the operating status of the module, the status indicator pins are as follows: Pin Pin Name I/O Reset Value Pin Description Type 28 FW_Ready PD 29 SMS_Ready PD 30 USB_En/Disable PD Reserved CMOS 1.8V 39 Wakeup_Host PD Module wakes up Host (AP).

L816-AM Hardware User Manual Page 30 of 42 3.6.1 FW_Ready Firmware ready is a modem driven GPIO, which on power on reset, it should be low. Once the firmware in the modem is ready after boot, it should assert (high) GPIO. In an unlikely event of a firmware/modem crash, if a crash/exception handler is to be run, FW ready GPIO should be de-asserted. FW_Ready timing is shown in Figure 3-6,3-7,3-9。 3.6.2 SMS_Ready SMS ready is a modem driven GPIO, which should be low while power up/off and reset sequences. Whenever modem receives an SMS from the network, it should assert (high) GPIO during 100msec, then de-assert (low). SMS ready GPIO should be triggered by non-class 2 “SIM card data” messages regardless message storage status (even the storage is full and not be able to store new received message). SMS_Ready timing is shown in Figure 3-13: Figure 3-13 SMS_Ready Timing 3.6.3 Wakeup_Host The Wakeup_Host signal is used to wake the Host (AP) when there is an incoming call, SMS or other data requests.

L816-AM Hardware User Manual Page 35 of 42 4.4 RF PCB Design 4.4.1 Trace Routing Principle The L816-AM module supports dual antennas, which meets the requirements for LTE of 3GPP. The MAIN_ANT is used to transmit and receive RF signals, while the DIV_ANT is used to receive RF signals. Using diversity antenna to improve the receiving sensitivity of RF antenna and double the download rate. Since L816-AM is an LTE module, dual antennas should be applied to meet the performance requirements. The L816-AM module does not provide RF connector itself, so routing RF traces are required for the connection with RF connectors or antenna feed points on the application mainboard. It is recommended to use the microstrip line for RF trace, with the insertion loss controlled within 0.2dB and impedance controlled at 50Ω. It is recommended to reserve a π circuit (the parallel inductors should connect to the RF trace) between the L816-AM module and the antenna connectors (or the feed points). The parallel devices are directly across the RF lines and no branch is allowed.
