TPM10
Cat-M1 Module
1. Functional Overview
TPM10 module provides the interconnection between
Interconnection with Cat-M1
−
TPM10 module receives and processes signals sent from Cat-M1 networks,
and then sends commands or data to terminals for performing the
operation and maintenance (O&M).
−
The module receives data and commands from terminals, transferring
those data and commands to Cat-M1 networks, and then delivers them to
application servers (ASs).
Interconnection with terminals
−
TPM10 module reads and uploads terminal data to the Cat-M1 networks.
−
The module receives commands from the Cat-M1 networks and performs
O&M for terminals.

1.2. Main Module Components
The TPM10 includes the following components.
A. SQN3330
This module includes SQN3330 Cat-1 baseband, a complete dual band RF front end, memory
and required circuitry to meet 3GPP E-UTRA (Long Term Evolution - LTE, Release 13 set of
specifications) and Wireless LTE Cat-M1 UE specifications.
SQN3330 is a single-chip LTE Cat M1 solution, which is designed specifically for narrowband
IoT applications, including sensors, wearables, and other low data, low power M2M and IoT
devices.
B. RF
The RF matching circuit.
C. Power system
The main power supply is “VBAT1“ and its range is 3.1~4.5V while the“VSIM” power supply
(3.0V) is for external SIM circuit.
D. Clock in system
TPM10 is using 32KHz clock in the module system.

1.3. LTE Low Power Modes
This module will automatically enter in low-power mode. It can be woken from low power
mode by the following external sources:
SIM_DETECT input signal to cope with SIM card insertion into a SIM card connector with
built-in hardware detection. The default configuration to wake-up the module is a
low-to-high transition.
The RTS0 input signal whenever data traffic is initiated by the host connected to the
module UART0 with hardware flow control; The default configuration to wake-up the
module is a high-to-low transition.
Two dedicated input signal WAKE0 and WAKE1; The default configuration to wake-up the
module is on a high-to-low transition. This can be modified by software. As example, these
signals can be used to detect an alarm from an external IC such as a sensor. Software can
disable the wake-up functionality on these signals.
A subset of GPIO input signals: GPIO2, GPIO3, GPIO25, GPIO27, GPIO42; they are not
configured by default as wake-up source but software can configure them for future use.

4. ESD
The module has no electro-static discharge (ESD) protection measures, and its sensitive
pins need external ESD protection. Appropriate ESD measures need to be added during
the manufacturing/transporting/operation stages.
The table below shows the ESD requirements for the module.

5. EMC
The signal integrity and power integrity issues caused by electromagnetic compatibility
(EMC) need to be considered when you use the module to design. Below are some
suggestions:
The coupling of the module and other digital chips must be deployed remotely as far as
possible, in order to avoid mutual interference.
The power supply (CSS), clock, high-speed digital signals, EMI components, and RF
simulation parts must be deployed remotely as far as possible.
The CSS, clock, high-speed digital signals, EMI components, and antennas must be
coupled remotely as far as possible in space.
During cabling routing, RF reference ground, digital and analog areas should be
separated, and all cables are routed in compliance with specified requirements to
avoid mutual coupling between lines.
