TC35i: Migration from TC35 to TC35i PRELIMINARY 4 Hardware migration This chapter contains information regarding the hardware set-up, installation instructions and physical properties for both modules. Hardware features are listed in comparison tables related to power supply, RF, audio, SIM and RS232 serial interfaces with functionality descriptions. All features, except RF, are available through common host application interface. 4.
TC35i: Migration from TC35 to TC35i PRELIMINARY 4.2 Operating Modes Various operating modes for TC35 and TC35i modules are listed in the table below. TC35i module supports four additional sleep modes compared to TC35.
TC35i: Migration from TC35 to TC35i PRELIMINARY 4.3 Interface/connectors comparison TC35i/TC35 TC35 and TC35i are equipped with a 40-pin 0.5mm pitch ZIF connector that connects to the cellular application platform. The mentioned ZIF connector is completely the same for both devices. The host interface incorporates several sub-interfaces described in the following chapters TC35 and TC35i are totally PIN compatible.
TC35i: Migration from TC35 to TC35i PRELIMINARY 4.4 Power Supply 4.4.1 General TC35 and TC35i need to connect the power supply to the ZIF connector (5 pins each VBATT+ and GND). Power supply has to be a single voltage source at BATT+. Power Supply ASIC handles all the key functions for supplying power.
TC35i: Migration from TC35 to TC35i PRELIMINARY 4.4.2 Power up / down scenarios TC35 and TC35i are fully identical regarding the power up/down scenario with the following exception: To actually turn off the TC35i, the emergency shutdown line has to be driven to ground for ≥ 3.2s. The TC35 emergency shutdown line needs to be driven to ground for ≥ 3.5s For further information please consult the HW manual for TC35 and TC35i. 4.4.
TC35i: Migration from TC35 to TC35i PRELIMINARY ^SCTM_B: -2 Alert: Tamb of board <-25°C. TC35i switches off immediately. Alert: Tamb of board <-29°C. TC35i switches off immediately. The table below shows which conditions will wake up TC35 and TC35i from sleep mode As it can be seen from the following table TC35i supports four sleep modes (5,6,7,8) more then TC35.
TC35i: Migration from TC35 to TC35i PRELIMINARY 4.5 RTC backup The internal Real Time Clock of is supplied from a dedicated voltage regulator in the power supply ASIC which is also active when TC35 and TC35i are in POWER DOWN status. Alarm function is included that allows waking up TC35 and TC35i without logging to the GSM network. On the TC35i board a serial resistor is placed next to the VDDLP line in order to limit the input current of an empty capacitor.
TC35i: Migration from TC35 to TC35i PRELIMINARY 4.7 Interfaces TC35 and TC35i interfaces are compatible. The following chapters shows a detailed comparison values for each interface. For further information please consult the TC35i HW manual 4.7.1 Serial Interface Each device uses the same serial interface type with identical pin positions.
TC35i: Migration from TC35 to TC35i PRELIMINARY 4.7.3 Antenna Interface 4.7.3.1 General Both devices TC35 and TC35i use a GSC connector to establish the RF connection to the host application. The table below shows a RF interface overview for each device.
TC35i: Migration from TC35 to TC35i PRELIMINARY 4.8 Electrostatic discharge TC35 and TC35i are identical protected against Electrical Discharge. For additional information about ESD please consult the actual specification 4.9 Mechanical Dimensions TC35 and TC35i provide the same type of connectors and mounting holes on the board. The position of mounting holes is identical as with TC35, as well as the order of external connectors.
TC35i: Migration from TC35 to TC35i PRELIMINARY 4.10 Mounting and installation Appropriate installation and mounting to the host housing / enclosure is essential for reliable operation of the GSM engine. TC35i & TC35 The TC35 board provides three mounting holes. To properly mount it to the host device you can use M1.6 or M1.8 screws plus suitable washers. The maximum diameter of the screw head, including the washer, must not exceed 4 mm.

TC35i: Migration from TC35 to TC35i PRELIMINARY 5 AT-Commands migration TC35i was intended as a "feature-superset" successor to TC35. AT Cellular command structure for TC35i corresponds to that of TC35 with the added improvements and new features. Available commands for both TC35i and TC35 are listed and classified according to their implementation within each of the modules. The entire command set of TC35 is supported by TC35i.
