LZT 123 1834 34 5.3 Genera l Electrical and Log ical Characteri stics The core digital IO i s based upon 1.8V technology in the baseband chipset. All external IO signals undergo bi-directional level shifting on the ph ysical module to provide flexibility to users of different vo ltage technology.
LZT 123 1834 35 Figure 5.3-1 Common Level Shifte r Circuit (VREF as a n Output) The output impedance of the Maxim chip is 6kohm , so you must ensure that your application impedance to ground or supply is high enough to allow for full voltage swing. A minimum application impedanc e of 56kohm should be assumed.
LZT 123 1834 36 5.3. 1.2 I2C Level Shifter Interface Because of the nature of the I 2 C interface signals, SDA (data) & SC L (clock), they utilize a different type of level-shifting tec hnolo gy to that of the ‘common’ IO .

LZT 123 1834 43 As a safety precaution, the battery cell vo lt age must be at least 2.5 V before fast- charge is allowed to take place. If the b attery cell voltag e is less than 2.5 V, it is considered either d eeply discharged or sho rted. To protect a Li- ion cell from the damage that may occur if it is fast-charged from this state, a 3 .
LZT 123 1834 44 Li-Ion batteries generally provide long storag e life with few limiting condition, and offer problem-free charge after long storag e. Under normal conditions, the lithium ion battery has a life of more than 500 charge/discharge cy cles.
LZT 123 1834 45 To determine battery life, on a full char ge, the following rule of thumb can be applied: Standby time = Bat tery Capacity (mAh) / Idle current (mA) Call time (voice or data) = Battery Capacity (mAh) / Call cu rrent (mA) Example 1 – Standby time: A 600mAh rated Li-Ion battery, from fully charged (around 4.
LZT 123 1834 46 Example 3 – Typical Operation: A module performing periodic network dat a transfers and communicating intervallic status information to its host would spend its non-active periods in sleep mode.

LZT 123 1834 74 6 Antenna Connector The wireless mo dem’s antenn a connector allows transmission of the r adio frequency (RF) signals from the wireless modem to an exter nal cust ome r supplied antenna. The connector is a micro-miniature coax ial MMCX through hole mounted socket.
LZT 123 1834 75 7 Hints for Integrating the Wireless Modem This chapter gives you advi ce and he lpful hints on how to integrat e the wireless modem into your application from a hardware perspective.
LZT 123 1834 76 Do not connect any incompatible component or product to the module. Sony Ericsson does not warrant against defects, malfunction, non- conformities or deviation caus ed by the conn ection of incom patible components or products to the GR64.
LZT 123 1834 77 The wireless modem an d antenna may be damage d if ei ther come into contact with ground potentials other than the one in the users appl ication. Beware, ground potential are not always what they ap pear to be. In the final application, t he antenna must be positioned more than 20 cm away from human bodies.
LZT 123 1834 78 Before installing the wireless mo dem, use a n ordinary mobile telephone to check a possible location for it. In determining the location for the radio d evice and antenna, you should consi der signal strength as well as ca ble length.
LZT 123 1834 79 It is recommended that you use a cable with a maximu m resistance of 5 milliohm for the ground connection. AREFand GND are connected at a si ngle point i nside the wirele ss modem. The y must not be jo ined together in yo ur application.
LZT 123 1834 80 The antenna must be designed for the freq uency bands deployed in the regions that the wireless mod em is being used. For fixe d location s this may be dual bands (for example E-GSM900/GSM1800 in Europe; GSM850/GSM1900 in North America).
LZT 123 1834 81 • Noise can be caused by electronic devices and radio transmitters. • Path-loss occurs as the strength of the re ceived signal steadily decreases in proportion to the distance from the transmitte r. • Shadowing is a form of env ironmental attenuation of rad io signal s caused by hills, buildings, trees or even vehi cles.
LZT 123 1834 82 8 Embedded Applications The wirele ss modem has the ca pability to store and run customer written code in the form of a script during the processor’s id le time, throug h the use of an on board interpreter.
LZT 123 1834 83 Code cannot be ported directly from an ex isting application and loaded directly onto the wireless modem. It must be re-writt en in t he Sony Ericsson Mobile script language so that the wireless mo dem interpreter can function correctly.
LZT 123 1834 84 9 TCP/IP Stack An on board IP/TCP/UDP stack has been inte grated into the software negating the need for the customer to implement one in their own code base. This is accessible by using an embedded application (see section 9) using intrinsic functions.
