  • Page 34: General Electrical And Logical Characteristics

    5.3 General Electrical and Logical Characteristics The core digital IO is based upon 1.8V technology in the baseband chipset. All external IO signals undergo bi-directional level shifting on the physical module to provide flexibility to users of different voltage technology. An internal core IO regulator is used as a reference for the module-side logic, whilst the application (host-side) reference is fed by VREF in one of two implementations.
  • Page 35 Figure 5.3-1 Common Level Shifter Circuit (VREF as an 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 impedance of 56kohm should be assumed. Similarly, where a GPIO is used as an input, your application driver output impedance must not exceed 680 ohm.

  • Page 36: I2C Level Shifter Interface

    5.3.1.2 I2C Level Shifter Interface Because of the nature of the I C interface signals, SDA (data) & SCL (clock), they utilize a different type of level-shifting technology to that of the ‘common’ IO. The C level shifter IC uses an open drain construction with no direction pin, ideally suited to bi-directional low voltage (such as the GR64 1.8 V processor) I C port translation to the normal 3.3 V or 5.0 V I...

User application circuitry should connect all VCC pins together in to carry the current drawn by the wireless modem.

  • Page 39: Voltage Reference (Vref)

    The module has approximately 40µF of internal capacitance across the VCC pins. During initial power-up the host power supply will have to charge this capacitance to the operating voltage. This initial in-rush CAUTION current may exceed the module’s normal peak current, sometimes greater than an order of magnitude higher (depending upon the power supply design) for a short duration (generally a few microseconds).

    5.7 Battery Charging Input (CHG_IN) Name Direction Function CHG_IN Input Battery charger power For battery powered applications, the GR64 provides a charge input (CHG_IN) pin to aid and support battery charging. A typical application would power the wireless modem directly from a battery source connected to VCC (pins 1, 3, 5, 7, 9) then provide a dc power source to the CHG_IN connection (pin 11).

    As a safety precaution, the battery cell voltage must be at least 2.5 V before fast- charge is allowed to take place. If the battery cell voltage is less than 2.5 V, it is considered either deeply discharged or shorted. To protect a Li-ion cell from the damage that may occur if it is fast-charged from this state, a 3.6 V trickle-charge source is used to safely condition the battery cell.

There are many manufacturers of Li-Ion batteries worldwide. Sony Ericsson make no recommendations with regard to specific vendors, but here are some considerations...
  • Page 45 To determine battery life, on a full charge, the following rule of thumb can be applied: Standby time = Battery Capacity (mAh) / Idle current (mA) Call time (voice or data) = Battery Capacity (mAh) / Call current (mA) Example 1 – Standby time: A 600mAh rated Li-Ion battery, from fully charged (around 4.2V) to the module cut- off point (3.2V) will provide around 95% of its total charge capacity.
  • Page 46 Example 3 – Typical Operation: A module performing periodic network data transfers and communicating intervallic status information to its host would spend its non-active periods in sleep mode. If the module spends 30 mins each day on call (320mA), 30 second each hour performing housekeeping, monitoring and status tasks (110mA), and sleeps (2.1mA) during the intervening periods, an 1800mAh rated Li-Ion battery fully charged would typically provide...

    The antenna must be designed for the frequency bands deployed in the regions that the wireless modem is being used. For fixed locations this may be dual bands (for example E-GSM900/GSM1800 in Europe; GSM850/GSM1900 in North America). For applications which are mobile, users should consider whether three or all four GSM bands could be encountered.
