Trackpad Module Datasheet V1.09 Page 2 of 23 March 2021 Azoteq IQ Switch® ProxSense® Series 1 Hardware Description All trackpad modules are available on RoHS2 and REACH compliant FR4 PCB material. The module PCBs are 1mm thick and have an OSP finish, with tinned pads for the user required solder points. The standard modules are not Halogen free. The trackpad sensing is done with IQS572, connected to an 8x8 diamond grid for 1792 pixel resolution in the X and Y directions. The modules are supplied with 3M double sided adhesive tape (PSA). Only certain modules include a connector, please consult Section 11. Table 1-1: Summary of Trackpad Offerings Module Name Shape Size TPR40 Round Ø40mm TPR48 Round Ø48mm TPR54 Round Ø54mm TPE60 Ellipse 60mm x 46mm TPE48 Ellipse 48mm x 38mm TPS48 Rectangle 48mm x 38mm The TPR40 is also available in the Value Line series. The value line uses the IQS525 in place of the IQS572, with maximum resolution of 1024 x 1024. 1.1 PCB Specification - Material: 2-layer, FR4 PCB (non-HF material) &RQGXFWRUȝP&RSSHUR]&X Finish: OSP (tinned) Size: Module Specific PCB Final Thickness = 1.0mm +/- 10% Outline: Precision DIE-CUT Profile Copyright © Azoteq (Pty) Ltd 2017.

Trackpad Module Datasheet V1.09 Page 3 of 23 March 2021 IQ Switch® ProxSense® Series Azoteq 1.2 Module Orientation All the modules have a cut in the PCB indicating the top of the module, which could also be used to align the module on the application overlay. This Notch can be seen in Figure 1.1 Tip: An overlay must be secured to the module with double sided adhesive tape without air gaps for performance evaluation. Figure 1-1: Top Notch Illustrating Module Orientation. 1.3 Adhesive (PSA) Specification All 6 modules offered are supplied with double sided adhesive applied on the trackpad for ease of integration. The adhesive is kept with the liner kept in place, with a pull tab for easy removal without tearing: - Type: 3M 468 200MP Thickness = 0.13mm Liner = Polycoated Kraft Paper Liner w/ Pull-Tab (No glue on Pull-Tab) Adhesive sized to fit entire tracking area (module specific) 1.4 Total Thickness The total thickness given in Figure 1.2 does not include the protective liner on the adhesive. The liner needs to be removed when the module is assembled into the application. The highest part (thickest part of the module) of the assembly is a 0603 capacitor – C2.

The modules have a solder link, S1, which can select one of two sensitivity settings tuned for different overlay thicknesses. Table 1-2: Module Overlay Compatibility . Solder link S1 Overlay Range Open 1mm – 2mm Closed 2mm – 3mm For non-uniform overlays, the maximum curve in the overlay is limited to a 1mm height difference over the trackpad surface as shown in Figure 1.3.

Connect a solder link on S2 to select active low. The active level is applicable to all 5 output pins. Table 1-3: Module Output Pin Level. Solder link S2 Output Level Open Active High Closed Active Low 1.7 Finger Sizes The modules have the same number of rows and columns which results in different trackpad pitches.
