IQ Switch ProxSense Series IQS550EV02 Datasheet Trackpad demo module using IQS550-B000 1 Overview The IQS550-B000 is a trackpad solution with on-chip gesture recognition, flexible device setup and leading sensitivity management and adjustment. The IQS550EV02 uses a 13x9 diamond sensor pattern to detect user proximity and touch. Finger position co-ordinates are then identified and gesture outputs are generated. With effective co-ordinate filtering, and advanced processing algorithms, the IQS550 provides reliable and stable outputs. The IQS550EV02 is an assembled demo unit, which is ready to be evaluated using the Azoteq CT210/DS100 USB dongle and the IQS5xx-B000 PC GUI software. The trackpad has a Mylar overlay material, which provides a smooth tracking surface and outputs high performance finger coordinates. 2 The sensor reports these outputs via standard I C protocol to Figure 1.1 IQS550EV02 the master and it is also fully configurable and programmable Trackpad Module via this interface. The IQS550EV02 is a standard IQS5xx-B000 product, and thus the IQS5xx-B000 product datasheet can be referenced for all relevant information: IQ Switch ProxSense Series Prox threshold (TP) 30 Prox threshold (ALP) 6 Touch threshold set 16 Touch threshold clear 10 ATI Target (TP) 700 ATI Target (ALP) 450 ATI C (TP) 1 ATI C (ALP) 21 Active Mode report rate 13 Idle Touch report rate 50 Idle Mode report rate 75 LP1 report rate 80 LP2 report rate 160 - - Active Mode timeout 5 Idle Touch timeout 60 Idle Mode timeout 10 LP1 timeout 10 Total multi-touches 5 X & Y resolution 1024 x 768 To obtain the full device configuration simply connect the trackpad module to a CT210/DS100 and run it with the IQS5xx-B000 PC GUI software. At start up all GUI parameters are updated to match the on-chip values, and can therefore easily be read back in the GUI. 3 Connecting to PC The module has a breakout PCB which converts the standard TPS65 flex connector to a 10- way CT210/DS100 compatible connector. 3.1 Hardware Connections To connect the IQS550EV02 to the PC, simply connect the 10-way ribbon cable from the CT210/DS100 to the P1 connector on the trackpad module. The following table shows the connections required.
