CAUTION: A8000 module is an ESD (electrostatic discharge) sensitive device. Electrostatic
charges as high as 1 K Volts readily accumulate on the human body and test equipment and can
discharge without detection. Permanent damage may occur on devices subjected to high-energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

1．Introduction
1.1 Overview
LONGSUNG A8000 is a dual band GSM/GPRS module that works on 850MHz/1900MHz.
Powered by Infineon PMB7880 chipset, A8000 features GPRS multi-slot class 10 and supports the
GPRS coding schemes CS-1, CS-2, CS-3 and CS-4.
With power saving technique, A8000 can minimize current consumption to as low as 5.5mA in
SLEEP mode, and is able to wake up on demand and to resume power saving automatically if no
activity is required.
For battery powered applications, MC55/56 features a charging control which can be used to charge
NiCd, Ni-Mh, Li-Polymer and Li-ON batteries. The charging circuit must be implemented outside
the module on the application platform.
1.2 A8000 Key Features

1.3 Operating Modes
The table1-2 below briefly summarizes the various operating modes referred to in the following
chapters.
Table1-2 Overview of operating modes
Mode
GSM / GPRS
SLEEP
Function
Module will automatically go into SLEEP mode if there is no on air or audio activity is
required and no hardware interrupt (such as GPIO interrupt or data on serial port).
In this case, the current consumption of module will reduce to the minimal level.
During sleep mode, the module can still receive paging message and SMS from the
BTS.
GSM IDLE
Software is active. Once registered to the GSM network, paging with BTS is carried
out, and the module is ready to send and receive.
GSM TALK
Connection is going on between two subscribers. In this case, the power consumption
depends on network settings.
GPRS IDLE
Module is ready for GPRS data transfer, but no data is currently sent or received. Power
consumption depends on network settings and GPRS configuration (e.g. multi-slot
settings).

GPRS DATA
SWITCH OFF
GPRS data transfer in progress. Power consumption depends on network settings (e.g.
power control level), uplink/downlink data rates and GPRS configuration (e.g. used
multi-slot settings).
Normal shutdown by using the SWITCH_ON. In this case only the power supply for the
RTC is remained. Software is not active. So the application interfaces cannot work.
Operating voltage (connected to VBAT) remains applied.
2.1 Power Supply
The power supply of the GSM engine has to be a single voltage source in the range of 3.5V～4.2V.
It must be able to withstand a sufficient current in a transmission burst which typically rises to 2A
instantly. Additionally, the power supply must be able to account for increased current consumption
if the module is exposed to inappropriate conditions, for example antenna mismatch.
2.1.1 Power Supply Pads on A8000
2 VBAT pads of A8000 connector are dedicated to connect the supply voltage, and 10 GND pads
are recommended for grounding. VDD_LRTC used to back up RTC and VDD_LIO is a 2.85V LDO
output for user application, max current 15mA, SWITCH_ON has the ON/OFF key function and
RESET_N can reset system with logic low level. Table2-1 lists the power supplies of A8000.

2.1.2 Turn On / Off A8000
2.1.2.1 Turn On A8000
To turn on A8000, the following procedures may be used:
• As default settings, A8000 will be turning on automatically when detecting voltage applied on
VBAT pad over 3.5V;
• If ON/OFF key function needed, the signal SWITCH_ON could be defined as power key to turn
on the system by pulling it up to VDD_LRTC.
2.1.2.2 Turn Off A8000
To turn off A8000, the following procedures may be used:
• As default settings, A8000 will be turning off automatically when detecting voltage applied on
VBAT pad below 3.3V;
• If ON/OFF key function needed, the signal SWITCH_ON could be defined as power key to turn
off the system by pulling it up to VDD_LRTC.
2.1.3 Power Saving
SLEEP mode can shut down unnecessary functions of the A8000 module to minimizes the power
consumption to the lowest level.
2.1.3.1 Sleep Mode
When no on air or audio activity required and no any hardware interrupt (such as GPIO interrupt or
data on serial port), A8000 will enter SLEEP mode automatically after 5 seconds, which can shut
down unnecessary functions of the A8000 module to minimizes the power consumption. In sleep
mode, A8000 can still receive paging or SMS from network and the serial will not be accessible
until A8000 be waked up.
2.1.3.2 Wake Up A8000 From SLEEP Mode
When A8000 is SLEEP mode, the following method can wake up the module.

• Receive a voice or data call from network to wake up A8000;
• Receive a SMS from network to wake up A8000;
• Hardware interrupts (such as Key press or GPIO interrupt).
2.1.6 RESET_N
RESET provides an external reset control signal for A8000 system. It should be noted that logic
LOW level is an effective signal for RESET_N

Normally the module is designed inside customer terminal, so about Electrostatic Discharge (ESD)
should be considered base on the requirement of terminal product. But for the module is protected
against Electrostatic Discharge in conveyance and customer production, and some second level
ESD protect design inside module.
The remaining ports are not special ESD protection in module, so the user should consider in the
final product, and therefore, they are only protected according to the Human Body Model
requirements.

Notes:*CC interrupt is an interrupt detecting mechanism that means system will capture the contents of a timer on specific
internal or external events, and they can compare a timer content with given values and modify output signals if they match.
IMPORTANT NOTE:
This module is intended for OEM integrator. The OEM integrator is still responsible for the FCC
compliance requirement of the end product which integrates this module.
20cm minimum distance has to be able to be maintained between the antenna and the users for the host
this module is integrated into. Under such configuration, the FCC radiation exposure limits set forth for
an population/uncontrolled environment can be satisfied.
Any changes or modifications not expressly approved by the manufacturer could void the user's
authority to operate this equipment.
USERS MANUAL OF THE END PRODUCT:
In the users manual of the end product, the end user has to be informed to keep at least 20cm
separation with the antenna while this end product is installed and operated. The end user has to be
informed that the FCC radio-frequency exposure guidelines for an uncontrolled environment can be
satisfied. The end user has to also be informed that any changes or modifications not expressly

approved by the manufacturer could void the user's authority to operate this equipment. If the size of the
end product is smaller than 8x10cm, then additional FCC part 15.19 statement is required to be available
in the users manual: This device complies with Part 15 of FCC rules. Operationis subject to the following
two conditions: (1) this device may not cause harmful interference and (2) this device must accept any
interference received, including interference that may cause undesired operation.
LABEL OF THE END PRODUCT:
The final end product must be labeled in a visible area with the following " Contains TX FCC ID: XXXXX
".
If the size of the end product is larger than 8x10cm, then the following FCC part 15.19 statement has to
also be available on the label: This device complies with Part 15 of FCC rules. Operation is subject to
the following two conditions: (1) this device may not cause harmful interference and (2) this device must
accept any interference received, including interference that may cause undesired operation.
