1: Leave pin 142 floating; the module can be turned on automatically when a power supply exists. 2: Pin 144 can be used as a wake-up as the module enters deep-sleep status. The default configuration is active high to wake up the LGA module. 3: The VREF voltage will turn off when entering the deep sleep state. 4:UART signal is better to retain in low state before the ALT1250 voltage is ready. 5:145 pin EXT_RST_N should use external 1.8V for pull up voltage Normal Internal Use Confidential Restricted Confidential 15 / 42 Product Technical Specifications 3.Electrical Specifications 3.1 Power Supply The IMA2A module is supplied through the power signal with the following characteristics.

Table 3-2. LTE power consumption 3.3 Control Interfaces This section describes the power on/off, wake-up, and reset interface for controlling the module. 3.3.1 Power-On Signal This function is not available in the present firmware; the module will be turned on automatically when the power supply exists. Set this pin as floating or use 0 as a reserve. 3.3.2 Wake-Up Interface In applications where power consumption is a major factor in performance metrics
(such as battery-operated sensors that are based on IOT/M2M modem solutions and also include a third-party host), it is necessary to define a simple interface that will enable the modem or the host to independently enter low power states whenever possible and the other respective modem or host side to wake it up once required. For example, if the host has no data to transmit or any other tasks to perform, 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 then receives data, it must wake-up the host. A similar converse requirement exists. For example, if the modem is in a low power Normal Internal Use Confidential Restricted Confidential 17 / 42 Product Technical Specifications state and the host then 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 by toggling a wakeup signal high and allowing the other to enter sleep mode when not required by toggling it low. WAKEUP_IN (Host: Output; Modem: Input):
LOW: The SoC does not require the Modem (allowing it to sleep). HIGH: The 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. Note: WAKEUP_OUT function will be updated in the future. 3.3.3 Reset Signal The Reset Signal is a hardware reset signal to control the system reset directly. You can connect it to a key or a control signal. Reserve a 100k resistor to pull up to VREF and maintain a sufficient physical distance between the reset signal trace and noise and radiating signals on the PCB. 3.3.4 WWAN state Note:WWAN_STATE function will be updated in the future. 3.4 UART Interface There are two UART interfaces: a 4-bit for high-speed data transfer, and the UARTs. Definitions of the IMA2A are listed below. 1. UART0 for PPP and AT Normal Internal Use Confidential Restricted Confidential 18 / 42 2. UART2 for firmware download, recovery mode, and firmware debug view Product Technical Specifications Figure 3-1. UART connection (example) 3.5 UIM Interface IMA2A modules provide a UIM_DETECT input pin for UIM connectors to detect a UIM card. When a UIM card is present, UIM_DETECT should be high (1.8 V). If a UIM card is absent, UIM_DETECT should be low. Pulling UIM_DETECT to VREF with a 100k resistor is necessary. We recommend placing a 0.1 F and a 33 pF capacitor between UIM_VCC and the Ground in parallel. We also recommend placing a 33 pF capacitor between UIM_RESET, UIM_CLK, and UIM_DATA and the Ground in parallel. Refer to Figure 5 for details. We also recommend placing an electrostatic discharge (ESD) protection circuit near the UIM socket as close as possible. The Ground pin of the ESD protection component must be well-connected to the Ground plane. The following figure shows an example of a UIM card circuit. The default configuration is active High.

Normal Internal Use Confidential Restricted Confidential 34 / 42 Product Technical Specifications 6.5 Interference and Sensitivity This section includes tips to help developers identify interferences that may affect the IMA2A module when used in systems. Interference from other wireless devices We highly recommend checking the RX performance of entire systems within the shielding environment. Good isolation (ex.: Wi-Fi antenna, GPS antenna) is required between the other wireless system antenna and the IMA2A module LTE antenna. Interference from the host interface High-speed signal-switching elements in systems can easily couple noise into the module (ex.: DDR memory, LCD modules, DC-to-DC converters, PCM signals). Normal Internal Use Confidential Restricted Confidential 35 / 42 Methods to avoid sources of interference 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 IMA2A module is well shielded; high-speed elements (Ex.: DDR memory, LCD modules, DC-to-DC converters, PCM signals) on a system should have shielding reserved during the early stages of development. 6.6 Antenna design requirement The antennas shall must meet below specification:

Normal Internal Use Confidential Restricted Confidential 37 / 42 Product Technical Specifications Process limit:
Normal Internal Use Confidential Restricted Confidential 38 / 42 6.8 PCB Pad Design We recommend a non-solder mask with defined (NSMD) type for the solder pads of the PCB on which IMA2A modules will be mounted. This type of design enables high soldering reliability during the SMT process. We recommend not placing via or micro-via that is not covered by solder resistance within 0.3 mm around the pads unless it carries the same signal of the pad itself. Refer to the following figure. Only blind holes are allowed in the pad. Through holes are not allowed. Normal Internal Use Confidential Restricted Confidential 39 / 42 6.9 Stencils WNC suggests using a stencil-foil with thickness of more than (or equaling to) 0.12 mm for module SMTs and a diagonal pattern to prevent voids during reflow.

Normal Internal Use Confidential Restricted Confidential 40 / 42 Product Technical Specifications 7.Safety Recommendations Be sure use of this product is allowed in the country and in the environment required. Use of this product may be dangerous and must be avoided in the following areas:
Where it may interfere with other electronic devices in environments such as hospitals, airports, and aircraft Where there is a risk of explosion such as gasoline stations and oil refineries The user is responsible for compliance with the legal and environmental regulations of their location of use. Do not disassemble the product; any evidence of tampering will compromise the warrantys validity. We recommend following the instructions of the hardware user guides for a correct wiring of the product. The product must be supplied with a stabilized voltage source, and the wiring must conform to relevant security and fire-prevention regulations. This product must be handled with care; avoid any contact with the pins because electrostatic discharge may damage the product. Exercise the same level of caution regarding the UIM card; carefully check the instructions for its use. Do not insert or remove the UIM when the product is in power-saving mode. The system integrator is responsible for the functioning of the final product;
therefore, care must be taken for the external components of the module as well as for project or installation issuesthere may be a risk of disturbing the GSM network or external devices or of impacting device security. If you have any questions, refer to the technical documentation and the relevant regulations in force. Every module must be equipped with a proper antenna with specific characteristics. The antenna must be installed with care in order to avoid any interference with other electronic devices.
