First, TC35 part of the debugging parameters

1, TC35 current consumption indicators:

1> TALK mode of peak, 1.8A

2> Typical mode of talk mode (TALK mode), 300mA @ 900MHz / 270mA @ 1800MHz

3> Idle mode (IDLE mode) current consumption, 10mA

4> Sleep mode (SLEEP mode) current consumption, 3mA

5> Power consumption (Power Down mode) of the current consumption, 50mA

2, on the LED lights show the state

SYNC pin can be used to output a synchronization signal (synchronization signal), can also be used in the application to control the output of a LED state. : SYNC side through a transistor or gate to control the LED. A simple circuit connection is: SYNC side through a resistor connected to the base of the NPN transistor (such as 9013), the emitter is directly grounded, the collector through a current limiting resistor connected to the negative LED, LED positive termination VCC. LED operating mode is completely similar to the synchronization signal, shows the working status of TC35:

1> LED off, indicating TC35 power off, in hibernation, alarm or simple charging mode

2> 600 ms On / 600ms off, the SIM card is not inserted, or the personal status is not registered / canceled, or the network is searching, or user authentication is in progress, or network registration is in progress

3> 75ms light / 3s off, that the network registration is successful (control channel and user exchange information is completed), no calls

4> LED lights, depending on the type of call: voice call, data call, in the establishment or completion of the state.

3, on the VDD side:

TC35 normal operation, the VDD pin output signal amplitude (about 60ms after the boot generated): 2.9V / 70mA, can be used as external applications.

Idle or talk mode: VDDout = 2.9V?% @ 70mA Imax = 70mA; Power off mode: VDDout = 0V.

4, on the VBATT + side:

TC35 operating voltage input terminal VBATT +, the voltage amplitude of 3.3V-5.5V, Vtyp = 4.2V, the maximum current Imax 2 A @ GSM antenna return loss (return loss) 6 dB. It must be noted that the minimum operating voltage can not be less than 3.3V, otherwise the voltage will drop, resulting in TC35 to stop working. Since the peak current of the VBATT + pin is 2A, a GSM transmission pulse may cause a significant voltage drop, and the inherent inherent impedance of the flat flexible connection of the external power supply may also be lost. Therefore, at any time, must ensure that the VBATT + voltage can not be less than 3.3V, and the voltage drop difference can not exceed 400 mV. In addition, in order to ensure that the voltage drop value of the TC35 in the transmitted pulse interval is at its minimum, a flat flexible FFC cable with a short connection module and a ZIF block shall be used with a length of no more than 200 mm and a low-impedance power supply.

5, on the POWER side:

TC35 charging voltage positive terminal POWER, if through an external power supply (such as charger) power supply, should ensure that Imax = 500 mA, Vin = 5.5-8V.

6, on / IGT (Ignition) side:

TC35 trigger the ignition signal / IGT, with the OC door or a simple switch to pull down the terminal level to open the module, active low. In the idle / talk / shutdown mode: Vout = 2.0V, Vlow, max = 0.45V @ Iout = 10, tlow 100ms. For the processing of the ignition signal IGT, it is necessary to first pull down the pin level to ground and maintain at least 100 ms.

Note that if you supply power via the charger circuit (connected to the POWER pin), or through battery power (connected to the VBATT + pin), then IGT?

7, on the PD (Power down):

TC35 off the power supply side / PD, shutdown signal pulse, the signal waveform ~~~ | ______ | ~~~, pulled low to low, at least 3.5 seconds to maintain effective. Vin, low, max = 0.45V @ I = 0.1mA, can be used OC door or a simple switch to achieve, through the shutdown signal can be closed TC35. And the IGT pin to apply a low-level pulse signal can re-open the module and the system. In addition, the shutdown signal terminal / PD can also be used to implement the watchdog signal output: Vout, low = 0.35V @ 0.01mA, Vout, high = 2.30V @ -0.01mA, fout = 0.5-2.0Hz

8, start TC35 way:

TC35 can be activated by the following way to start work

1> Triggered by ignition line IGT, into normal working condition

2> through the power cord, began to enter the charging area

3> through the RTC interrupt, start to enter the alarm mode

9, TC35 boot operation timing

When the application is started, the TC35 power-up process must be carried out as follows:

1> Until the VBATT + pin level exceeds 3.0V, the signal level of the line can be changed.

2> VBATT + feet up to 3.0V after the level of maintenance to maintain 10 milliseconds, before pulling down the IGT line signal level. The level drop time (falling time) of the IGT line must not exceed 1 ms.

3> In addition, the low level signal of the IGT line must be maintained for at least 100 ms.

4> In the IGT line signal conversion interval must ensure that VBATT + voltage can not be less than 3.0V, otherwise the module can not be activated.
