SIEMENS wireless modules, MC35i in this case. Information provided here is based on official technical manuals and released specifications for MC35 and MC35i. The naming conventions used in this document follow those of source documentation.
Migration from MC35 to MC35i P R E L I M I N A R Y 3 Feature migration Feature comparison for both modules introduced in the table below. Only main specifications are listed. General description Table 1: General description a)
Via serial interface and SIM interface Certification and standards Both MC35 and MC35i comply with the same directives and standards. However, please note that a new R&TTE approval of the host application is required after migration from MC35 to MC35i.
MC35i and MC35 are supporting GPRS multi-slot class 8 (4 Rx, 1 Tx time-slot) and the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4. Modules operate in GSM 900MHz and GSM 1800MHz frequency bands.
P R E L I M I N A R Y 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.
P R E L I M I N A R Y The table below 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).
P R E L I M I N A R Y 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 completely the same for both devices.
Power supply General 4.4.1 MC35 and MC35i need to connect the power supply to the ZIF connector (5 pins each V BATT+ 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.
MC35 and MC35i are fully identical regarding the power up/down scenario. Automatic shutdown 4.4.3 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. Automatic shutdown takes effect if: æ...
MC35 and MC35i are fully identical regarding the internal Real Time Clock. Control signals Input and Output control signals are identical with both MC35 and MC35i device. Interfaces MC35 and MC35i interfaces are compatible. The following chapters shows a detailed comparison values for each interface.
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.

Furthermore, the covers must not be used to apply any solder joints. For snap in concept please be aware that the MC35i PCB is thinner then the MC35 PCB. 18 of 30 12.03.03...
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. The entire command set of MC35 is supported by MC35i.
P R E L I M I N A R Y List of jointly supported AT commands AT-commands listed in the tables below are supported by both MC35i and MC35. Default settings for command parameters, however, may be different. NOTE: Many commands are available only after the PIN has been entered. For full list, please refer to respective AT reference manuals.
