Migration from MC35 to MC35i R E L E A S E D 3 Hardware migration This chapter contains information about the hardware design, installation instructions as well as physical properties for both modules. Hardware features are listed in comparison tables related to power supply, RF, audio, SIM and serial interfaces with functionality descriptions. All features, except RF, are available through common host application interface. 3.
Migration from MC35 to MC35i R E L E A S E D 3.2 Operating modes The operating modes for MC35 and MC35i modules are listed in the table below. The MC35i module supports two additional sleep modes compared to MC35. For further details please consult the MC35i manual. The table below shows operating modes overview for both devices. Table 4: Operating modes Mode Function MC35 MC35i Normal operation GSM / GPRS SLEEP Power-save modes set with AT+CFUN command. Software is active to a minimum extent.
Migration from MC35 to MC35i R E L E A S E D The Table 5 shows which conditions will wake up MC35 and MC35i from sleep mode As shown in the following table, MC35i supports two additional sleep modes (7 and 8).
Migration from MC35 to MC35i R E L E A S E D 3.3 MC35 / MC35i – interface and connector comparison MC35 and MC35i are equipped with a 40-pin 0.5mm pitch ZIF connector that connects to the cellular application platform. The ZIF connector is physically the same for both devices. MC35 and MC35i are PIN compatible, with the exception of the pins POWER and ACCU_TEMP. Furthermore it should be noted that some of the MC35 signal names were changed as well as MC35i does not support the charging functionality.
Migration from MC35 to MC35i R E L E A S E D 3.4 Power supply 3.4.1 General MC35 and MC35i 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+. The Power Supply ASIC handles all the key functions for supplying power. The following tables show an overview of main power supply points with MC35 and MC35i. Table 7: Power supply signals General Feature MC35 MC35i Ignition (/IGT): Rpullup = 200kW.
Migration from MC35 to MC35i R E L E A S E D 3.4.3 Automatic shutdown To ensure proper operation of all assemblies under varying conditions, such as temperature, input voltage, transmission power etc., MC35 and MC35i features protection elements for automatic shutdown.
Migration from MC35 to MC35i R E L E A S E D 3.6 Control signals Input and Output control signals are identical with both MC35 and MC35i device, except for POWER and ACCU_TEMP. 3.7 Interfaces MC35 and MC35i interfaces are compatible. Detailed comparison values for each interface can be found in the following chapters. For further information please consult [3]. 3.7.1 Serial interface Each device uses the same serial interface with identical pin positions as described in [1], [3]. 3.7.
Migration from MC35 to MC35i R E L E A S E D 3.9 Mechanical dimensions MC35 and MC35i provide the same type of connectors and mounting holes on the board. The position of mounting holes is identical as with MC35, as well as the order of external connectors. The outline mechanical dimensions are identical with both devices except the height. MC35i is a single side mounted device and is therefore thinner than MC35.
Migration from MC35 to MC35i R E L E A S E D 3.10 Mounting and installation Appropriate installation and mounting to the host housing / enclosure is essential for reliable operation of the GSM engine. MC35 & MC35i The MC35i 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.
Migration from MC35 to MC35i R E L E A S E D 4 AT commands migration AT Cellular command structure for MC35i incorporates that of MC35 with the added improvements and new features. Available commands for both MC35i and MC35 are listed and classified according to their implementation within each of the modules. MC35i supports the entire command set of MC35. Differences in test, query and execution syntax as well as in available parameters are noted for each command.
