1Introduction
1.1 Overview The GR47/GR48 belong to a new generation of Sony Ericsson Mobile
Communications GSM modules. This document describes the main
characteristics and functionality of the GR47/48, two dual band
products for 900/1800 MHz and 850/1900 MHz GSM bands
respectively.
They are intended to be used in both machine-to-machine applications
and man-to-machine applications. The module serves its purpose
when there is a need for sending and receiving data (by SMS, CSD,
HSCSD, or GPRS), as well as making voice calls over the GSM
network.
GR47/GR48 are business-to-business products. It is intended to be
sold to manufacturers, system integrators, applications developers-
developing solutions with wireless communication. The module is
intended to be integrated by the system integrator within an
application. The module and the external application will form a
system for wireless communication.
A typical system is one where a micro controller in an external
application communicates with the module over its serial interface.
The micro controller will control the module, via the supported set of
AT commands. It is assumed that the system integrators have a high
technical knowledge and the ability to integrate the module into a
system. For the GR47/GR48 modules some interesting applications
are the following:
•Fleet and Asset Management
•Vending Machines
•Security and Alarm
•Other telemetry applications

1.2 Features The module performs a set of telecom services (TS) according to
GSM standard phase 2+, ETSI and ITU-T. The functions of the
module are implemented by issuing AT commands over the serial
interface. Supported AT commands are listed in section 5, these are
defined further in GSM 7.05/7.07 and the GR47/GR48 integrator’s
manual.

1.2.2 SMS The module supports the following SMS services:
•Sending: MO, both PDU and Text mode supported.
•Receiving: MT, both PDU and Text mode supported.
•CBM is a service, in which a message is sent to all subscribers
located in one or more specific cell(s) in the GSM network, for
example, cell location information.
•SMS STATUS REPORT according to GSM 03.40.
The maximum length of an SMS message is 160 characters when
using 7-bit encoding. For 8-bit data, the maximum length is 140
characters.
The module supports upto 6 concatenated messages to extend this
function.
1.2.3 Voice calls The GR47/GR48 offers the capability of MO and MT voice calls, as
well as supporting emergency calls. In addition to this multiparty, call
waiting and call deflection features are available. Some of these
features are operator specific.
The module offers normal analogue input/output lines, analogue audio
input/ output lines in differential modes, and digital audio interface,
with the possibility of accessing internal points within the digital
audio lines. Moreover, the GR47/GR48 have an embedded echo
canceller and noise suppression, which provide high quality audio.
The module supports HR, FR and EFR voice coding, provided that
EFR is available in the network.
1.2.4 Data The module supports the following data protocols:
•General Packet Radio Service (GPRS). The modules are Class B
Terminals, which provides simultaneous activation and attach of
GPRS and GSM services. The GR47/GR48 modules are GPRS
4+1 devices, which are capable of transmitting in one timeslot per
frame (uplink), and receiving in a maximum of four timeslots per
frame (downlink).
•Circuit Switched Data (CSD). GR47/GR48 modules are capable of
establishing a circuit switch data link at 9.6 kbps.
•High Speed Circuit Switched Data (HSCSD). GR47/GR48 supports
HSCSD communication, with one timeslot per frame capacity in
the uplink and two timeslots per frame capacity in the downlink
(2+1).

logic inputs or outputs powered from 2.75 V ± 5 %. Whenever a
signal is defined as Dig. 2.75 V, the following electrical
characteristics shall apply.
Parameter Min. Typ. Max. Units Output

3.2.1 General Protection Requirements
All 2.75V digital inputs shall continuously withstand any voltage from
-0.5V up to 3.47V (3.3V + 5%) in the power-on or power-off
condition with no damage. All 2.75V digital outputs shall
continuously withstand a short circuit to any voltage within the range
from 0V to 3V.
! Note : This is for protection ONLY, the module cannot be driven
directly by a 3.3V micro processor, if this is done it will invalidate any
warranty claim on the module.
The SIM output signals and the SIMVCC supply cancontinuously
withstand a short circuit to any voltage within the range from 0V to
4.1V.

3.3 Grounds
Pins Name Description
2, 4, 6, 8, 10, 12 DGND Digital Ground
60 AGND Analogue Ground
There are two ground signals in GR 47/48, Analogue Ground
(AGND) and Digital Ground (DGND). The analogue Ground is
connected to pin number 60, and the Digital Ground is connected to
the System Connector Interface through pin numbers 2, 4, 6, 8, 10 and
12.
Note: All the Ground pins have to be connected to the application.
The AGND is connected to the DGND in the ME, and only there. It is
important that the AGND and the DGND are separated in the
application.
3.3.1 The Analogue Ground
The AGND lead is the analogue audio reference ground. It is the
return signal for Audio To Mobile Station (ATMS) and Audio From
Mobile Station (AFMS).
It shall be connected to the Digital Ground (DGND) inside the module
and only there. The application shall not connect DGND and AGND.
Parameter Limit
Imax ≅12.5mA
3.3.2 The Digital Ground (DGND)
DGND is the reference for all digital signals in the System Interface.
It shall also be the DC return for the power supply on VCC and
SERVICE. Each DGND pin is rated at 0.5 A. All DGND pins are
connected internally in the module.
All DGND pins should be connected commonly in the application.
Parameter Limit
Iaverage < 0.5 A No DGND pin canwithstand over 0.5 A
Imax < 600 mA (100 mA each)

GBBA/SEM/BMS 03:0001 Rev A19
3.4 Regulated Power Supply
Pins Name Description
1, 3, 5, 7, 9 VCC Regulated Power Supply
The regulated power supply, VCC, is connected to the pin numbers 1,
3, 5, 7 and 9.
3.4.1 Power Supply (VCC)
The VCC supplies the module with external power. Any other voltage
needed is generated internally.
Parameter Mode Limit
Voltage to be applied Nominal 3.6 Volts
Tolerance including ripple
13.4 Volts-4.0 Volts
Over voltages 5.5 Volts
Current Drive capability at TX Full Power < 600 mA (average))
< 2 A (Peak)
GR 47/48 have not internal capacitance to supply the large current
peaks during GSM transmission. Therefore on burst transmission the
application DC source is responsible for providing the appropriate
current.
Design application notes are available from customer support on
request.
3.4.2 Battery Charging Input (CHG_IN)
The battery charging pin is design to provide a charging current into a
battery. The precise algorithm is TBD but it will be one of the
following
•Generic charging algorithm implemented and further
refinements for the algorithm to be implemented through
embedded applications (see section 6)
•Specific charging algorithms for SEM approved batteries.

34 VIO O External power supply
3.5.1 Module ON/OFF
The module is powered ON/OFF by grounding (pulling low) pin 14 as
per figure 3.2 below. The pin should then be released as it has an
internal pull up to return it to the high state.
Note: Driving with 2.75V or 3.6V is not permitted and restricts
module functionality.
