subsystem and peripheral interfaces and functions uniquely designed to address the
power/performance/cost requirements of IoT and M2M applications. The CPU is based on
Qualcomm’s MDM architecture which offers OFDMA-related software based signal
processing capabilities that significantly exceed traditional communications ARM cores.
M18QF/M18QA Series modules provide a variety of interfaces including USB 2.0, SGMII, SPI,
UART, PCM, I2C, UIM & SDIO.

technology and band support information among different modules, please refer to table2
for detail information.
Note: 1.Refer to section6.6 for more information about industrial grade.
2.“√” indicates supporting. “×” indicates not supporting.
3. The 2nd harmonic of LTE B14 is not isolated completely from embedded GNSS
receiver, the interference would make GNSS de-sense seriously when LTE B14 and GNSS are
working simultaneously, the external GNSS receiver is recommended to use instead of
embedded GNSS in M18QA/M14QA.

Notes: *2. Do not pull pin143 WAKEUP_OUT to high; otherwise boot will fail.
*3. Pull Pin144 WAKEUP_IN to VREF with a 100k resistor and keep it high before
system boot process is complete.
*4. Pull pin142 POWER_ON to VREF with a 100k resistor for stability considerations.
*5. Refer to SGMII standard for more electronic characteristics.
*6. Refer to section 2.3, for more information please check USB2.0 standard
*7. Pull pin87 USB detect to VREF with a 100k resistor to enable module USB, pull
pin87 low to disable module USB, CPU USB PHY consumes some current when
USB is enabled.
*8. Do not pull pin52 to high before the system boot process is complete.
*9. Leave unused pins floating

*11. If voltage level of digital I/O from the other side is not compatible with module,
level shifter is recommended to transfer the voltage level to 1.8V.
Note2,3,4,8,9,10 must be followed otherwise module may fail or malfunction.
Below is the I/O default setting table to describe the level. It’s recommended to follow the
pulling High or Low to choose a suitable GPIO for application.

LTE module power input is VCC. The internal power chipset will transfer VCC to other power
Table 7. Power supply voltage level
level.
The M18QF/M18QA Series include an integrated power manager enabling single and direct
voltage supply from the battery, reducing the overall bill of materials. The typical voltage
3.8V is recommended.
Schematic suggestion: Must to separate module power supply to three paths to keep
power clean as below for TX spurious performance. The VPH_PWR is for Baseband and RF
transceiver, the VPH_PWR_RF is for RF PA, the VPH_PWR_RF_VBATT is for RF PA control
circuit.

Layout Suggestion: The 22μF, 0.1uF, 12pF and 8pF capacitors are required to place near

VCC pins as close as possible. Each power trace should possess
sufficient line width to withstand its respective current listed in the
table below:
The M18QF/M18QA Series modules comply with USB 2.0 high-speed protocol. The USB
input/output lines follow USB 2.0 specifications.
