INTRODUCTION
This document describes the hardware interface of the Sagemcom HiLoNC-3GPS M2M module used to connect the device application and the air interface.
1. 1
PRODUCT CONCEPT
The HiLoNC-3GPS module is one of the smallest available UMTS/HSPA+ moduleson the market with LGApins. The target application is the Machine to Machine (M2M) market including automotive, AMM (Automatic Metering Management), tracking system, alarm, etc. [. . . ] Signal VBACKUP Pin N° 28 Description Power supply for backup battery

VGPIO
This Voltage pin is the reference voltage for the internal digital I/O's and it can be used as a power supply and also as a module power status (ON/OFF). VGPIO is high when the module starts and remains at this level until the module is OFF. Signal VGPIO Pin N° 71 Description Digital Power supply and power up status

POWER SUPPLIES
Connecting all power supply pins, 3for the VBAT and 49for the GND, is recommendedto lower power signal path serial resistance.

POWER MANAGEMENT
3. 15
SLEEP MODES
There are two kinds of sleep modes, the "off mode" and "stand-by" mode as described below:
3. 15. 1 Off mode
When the module is in the off mode it cannot receive any calls or receive any AT commands but can be awakenedby using PWON signal [3].
3. 15. 2 Stand-by Mode Management
There are three stand-by mode management controls: · AT+KSLEEP=0 In this mode the sleep state is controlled by the host DTR and by the firmware: - DTR = 1 - The module never enters into the sleep mode - DTR = 0 - The module enters the sleep mode when it is ready and cannot be awakened with an AT command. Remarks: Even in this mode it is possible to use DTR signals to go from the data mode to the command mode. However, in this case, DTR has to be toggled from 1 to 0 then from 0 to 1. · AT+KSLEEP=1 In this mode the sleep mode state is only controlled by the firmware. However, to be sure to awaken the module, the "0x00" character must be sent.
The main interest of the AT+KSLEEP=0 mode is to be able to forbid the sleep mode from using the DTR signal. · AT+KSLEEP=2 In this mode the sleep state is never authorized in any DTR state.
Detailed descriptions of these modes are given in [4].
Here we give the logical state. HiLoNC-3GPS technical specifications 2011-10-20 - page 21/49

3. 15. 3 Powerconsumption
The power supply input of VBAT ranges from 3. 4V to 4. 2V and 3. 7V is nominal. All measurements in the communication mode are done at the maximum RF power transmission (PCL max). Off mode Stand-by mode Paging rate 2 connected to the network Stand-by mode Paging rate 5 connected to the network Stand-by mode Paging rate 9 connected to the network GSM900 / CSD mode in GSM850(PCL=5) communication DCS / PCS(PCL=0) GPRS when transmitting GSM900 / GSM850 data (CS-4 Class 10 4DL, DCS / PCS 1UL) EDGE when transmitting data (MCS-9, Class 10, 4DL, 1UL) GPRS stand-by mode 1 or 2 PDP context are open Current consumption during a burst UMTS Stand-by mode DRX=6 UMTS Stand-by mode DRX=9 UMTS data mode TX: Maximun power Channel: B1 : 9613, 9750, 9887 B8 : 2713, 2788, 2862 GSM900 / GSM850 DCS / PCS All band All band 1. 4mA GSM900 / GSM850 DCS / PCS Typ. 50 µA 3mA 1. 8mA 1. 4mA 280mA 200mA 600mA 520mA 310mA 310mA 3mA 1. 8mA 1. 4mA 260 mA 180 mA 600 mA 520 mA 310 mA 310 mA 25° C Max 100 µA 3. 5mA 2mA 1. 6 mA 290 mA 200 mA 750 mA 610 mA 430 mA 340 mA 4. 5mA 3. 5mA 3mA 280mA 200mA 650mA 550mA 330mA 320mA +85° C Typ.
The HILONC-3GPS behavior in the GPRS stand-by mode is similar to the GSM stand-by mode. The power consumption also depends on DRX and on other network settings (number of adjacent cells, etc. ). It is between 1. 4 mA and 2. 8 mA. 1. 95A 1. 75A 1. 75A 1. 2A 3 mA 1. 4 mA 1. 1A 3. 5 mA 1. 6 mA 3mA 1. 1A

A burst transmission occurs in the Standby, Communication and GPRS modes. This measurement is performed with a 22 µF capacitor in the power supply path required to remove the overshoot.
