A8000 User Guide Confidential 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.

A8000 User Guide Confidential 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.

A8000 User Guide Confidential 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.
