A8000 User Guide Confidential UA8000_User_Guide_V1.0 Page 5 of 22 2009/05/13 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 The GSM module A8000 supports audio, SMS, and data transfer. Table1-1 lists the features of A8000.

Table1-2 Overview of operating modes Mode Function GSM / GPRS SLEEP 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).
A8000 User Guide Confidential A8000_User_Guide_V1.0 Page 7 of 22 2009/05/13 GPRS DATA 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). SWITCH OFF 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. Table2-1: Power supplies of A8000 Signal Name PIN No. I/O Description Notes VBAT 61,62 I Positive operating voltage 3.3 V-4.2 V, Ityp ≤ 2 A during transmit burst, the minimum operating voltage must never fall below 3.3 V.

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.
