Read Me First TDA7210V Remote Control Rx-Board Design Example by Mipot S.p.A. K it C o n t e n t TDA7210V Remote Control Rx-Board PMAfob Remote Control Transmitter 1 antenna, ¼ lambda - reduced size Legal disclaimer sheet Dear Customer, Firmware source code and Hardware Thank you for working with Infineon Wireless Control products! design documentation available This TDA7210V Remote Control Receiver-Board represents a typical design example how the TDA7210V can be used as a receiving component in a remote control application. On the side of the TDA7210V there is a microcontroller decoding the received signal and driving the five output channels. This design is fully compatible to Infineon’s PMAfob remote control transmitter (see www.infineon.com/PMAfob). for download at All design information is available for download on the Infineon internet pages (see www.infineon.com/TDA7210V): PMAfob RKE demonstrator PMAfob Home Automation Schematic PCB layout Components list Microcontroller firmware (C source code) www.infineon.com/TDA7210V TDA7210V_RC_RxBoard_vx.y.zip Other available PMAfob demos: demonstrator The TDA7210V Remote Control Rx-Board was designed by one of Infineon’s recommended design houses for Wireless Control products: Mipot S.p.A.

Your Infineon Wireless Control Team www.infineon.com/TDA7210V www.infineon.com/PMAfob September 2010 Quick Start TDA7210V Remote Control Rx-Board Step-by-Step Quick Start Guide Please follow this step-by-step approach when you start up your TDA7210V PMAfob remote control demo for the first time: Check the placement of all jumpers on the board. By default the jumpers marked MSEL and CSEL must be in closed position. The power down mode selection jumper marked PWRDWN must be closed in position +V. All other jumpers or test pins on the board must be left in open position (except the power supply selection jumper 5V/7-15V – see below). See the picture on the right where all closed jumpers are marked. Connect the antenna to the SMA-connector marked RF IN. This application operates in the 434 MHz frequency band. Therefore, antennas with red marking are suitable. Connect a suitable power supply to the TDA7210V Remote Control Rx-Board. There are two alternatives: Regulated: Connect a regulated DC supply voltage of +5.0V to the screw terminals marked GND and 5V. In this power supply mode the related jumper must be placed in position 5V. Unregulated: Connect an unregulated DC supply voltage in the range between 7.0V and 15.0V to the screw terminals GND and 7-15V. In this power supply mode the related jumper must be placed in position 7-15V. Switch on the power supply. Press button S1 to activate the receive mode. LEDs DL1 and DL2 will signalize the receive-ready state. Upon delivery of the kit the enclosed PMAfob remote controller is already set to the correct protocol mode for this demo. By pressing buttons on the PMAfob related channel LEDs (CH1…CH5) on the TDA7210V Remote Control Rx-Board will change their state. Note: The PMAfob remote controller supports different protocol modes. This demo requires the mode XTEA-Frame/no encryption which is already configured upon shipment of the kit. The protocol mode may be changed by removing the battery from the PMAfob or accidently by holding buttons down longer than 3 seconds. In case your TDA7210V Remote Control Rx-Board does not react to any remote control commands anymore, follow these steps to reactivate the right protocol mode: Open the PMAfob housing and remove the battery for longer than 5 seconds. Reinsert the battery again. Hold down button CH5 for longer than 3 seconds. Hold down button CH4 for longer than 3 seconds. Now, protocol mode XTEA-Frame/no encryption is re-established and the demo shall operate as expected. Find more information about PMAfob protocol modes in the PMAfob User Guide. Early versions of PMAfob delivered with other kits may not support the protocol mode XTEA-Frame/no encryption. These may be re-programmed with newest PMAfob firmware (see www.infineon.com/PMAfob) for full compatibility with all applications. 2010 Antenna Colour Coding Green: 315 MHz Red: 434MHz White: 868 MHz Yellow: 915 MHz
