3.2 Control Interfaces
This section describes the power-on/off, wake-up, and reset interface for controlling
the module.
3.2.1 Power-on Signal (TBD)
The POWER_ON signal is an active low input signal used to enable or disable the
module. Do not toggle the PERST# pin during power-on. This signal has the highest
priority among the wakeup, the alarm signal, and the digital control pins.
There are three possible states of the module:
Module Off: VCC is not present.
Module Enabled: VCC is supplied, and the module is enabled.
Module Disabled: VCC is supplied, and the module is disabled.
The state transitions are defined as follows:
When voltage is applied to VCC, the module shall enter the Module Disabled
state.
An input to the POWER_ON pin shall trigger the transition from the Module Disabled
to the Module Enabled state. See Figure 6; a low pulse (tlow > 0s) on the POWER_ON
pad will enable the module after VCC is applied.
3.2.2 Wake-up Interface (TBD)
In applications where power consumption is a major factor in performance metrics
(such as battery-operated sensors that are based on an IOT/M2M modem solution
and also include a third-party host), definitions are necessary for a simple interface
that will enable both the modem and the host 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 or any other tasks, it may enter a
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 in the reverse case. 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 triggered by the host and received by
the modem; the other is triggered by the modem and received by the host.
Each side can wake the other by toggling a wakeup signal high and enabling the
Product datasheet
Normal Internal Use Confidential Restricted Confidential 14 / 29
other side to activate sleep mode 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.
When the IMS2 module functions as a modem, keep WAKEUP_IN high before the
system boot process is complete. After the system boot, maintain WAKEUP_IN in a
low state. The WAKEUP_IN and WAKEUP_OUT operation in host mode will be
discussed according to product specifications.
3.2.3 Reset Signal
The Reset Signal is a hardware reset signal to control the system reset directly. The
user can connect it to a key or a control signal. A low pulse after power on will reset
the module.
3.3 UART Interface
There are three UART interfaces; these interfaces are 4 bit for high-speed data
transfer, and the UART definitions of IMS2 are shown in Figure 3-2.

2. UART1 for debugging the DM tool and software upgrade
3. UART2 for the console
Figure 3-2. UART connection (example)
Product datasheet
Normal Internal Use Confidential Restricted Confidential 15 / 29
3.4 UIM Interface
IMS2 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 the UIM
card is absent, UIM_DETECT should be low. This is required to pull UIM_DETECT to
VREF with a 470 kΩ resistor. A 0.1 μF and a 33 pF capacitor are recommended to
place between UIM_VCC and Ground in parallel. We recommend placing a 33 pF
capacitor between UIM_RESET, UIM_CLK, and UIM_DATA and Ground in parallel.
(Refer to Figure 5.)
An electrostatic discharge (ESD) protection circuit is also recommended to place near
the UIM socket as close as possible, and the Ground pin of the ESD protection
component must be well connected to the Ground plane.
The following figure illustrates an example UIM card circuit. The default
configuration is active high.

3.8 RF Performance
Each IMS2 module has only one RF pad; developers must connect it via 50 Ω traces
to the main board.
Main antenna pad (Pin15) Primary RX/TX path
3.8.1 RF Pad Design
We recommended that a ground not be present under the surface of the RF pads in
the layout. Details are included below. Layer2 has the same exclusion area as Layer1.
Figure 3-5. Sample RF pad layout
Product datasheet
Normal Internal Use Confidential Restricted Confidential 19 / 29
The RF trace between RF pads and antenna should as shorter as possible with 50ohm
characteristic impedance.
The characteristic impedance depends on the dielectric of PCB, the track width and
the ground plane spacing. Microstrip type is required. The detail simulation as below.
Product datasheet
Normal Internal Use Confidential Restricted Confidential 20 / 29
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.

3.8.3 Interference and Sensitivity
This section includes tips to help developers identify interferences that may affect
the IMS2 module when used in systems.
Interference from other wireless devices
Harmonics, inter-modulated signals generated from wireless devices
within the RX ranges of the modules may result in degraded RX
performance.
We highly recommend checking the RX performance of entire
systems within the shielding environment.
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-DC
converters, PCM signals).
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 IMS2 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.
