General Description ams Datasheet [v1-05] 2014-Oct-24 TMG3993 Gesture, Color, ALS, and Proximity Sensor Module with mobeam™ Barcode Emulation The device features advanced Gesture detection, Proximity detection, Digital Ambient Light Sense (ALS), Color Sense (RGBC), and optical pattern generation/transmission for broadcast. The slim modular package, 2.36mm × 3.95mm × 1.36mm, incorporates an IR LED and factory calibrated LED driver. Gesture detection utilizes four directional photodiodes to sense reflected IR energy (sourced by the integrated LED) to convert physical motion information (i.e. velocity, direction and distance) to a digital information. The architecture of the gesture engine features automatic activation (based on Proximity engine results), ambient light subtraction, cross-talk cancelation, dual 8-bit data converters, power saving inter-conversion delay, 32-dataset FIFO, and interrupt driven I2C communication. The gesture engine accommodates a wide range of mobile device gesturing requirements: simple North-South-East-West gestures or more complex gestures can be accurately sensed. Power consumption and noise are minimized with adjustable IR LED timing. The Proximity detection feature provides object detection (E.g. mobile device screen to user’s ear) by photodiode detection of reflected IR energy (sourced by the integrated LED). Detect/release events are interrupt driven, and occur whenever proximity result crosses upper and/or lower threshold settings. The proximity engine features offset adjustment registers to compensate for system offset caused by unwanted IR energy reflections appearing at the sensor. The IR LED intensity is factory trimmed to eliminate the need for end-equipment calibration due to component variations. Proximity results are further improved by automatic ambient light subtraction. The Color and ALS detection feature provides red, green, blue and clear light intensity data. Each of the R, G, B, C channels have a UV and IR blocking filter and a dedicated data converter producing16-bit data simultaneously. This architecture allows applications to accurately measure ambient light and sense color which enables devices to calculate illuminance and color temperature, control display backlight, and chromaticity. mobeam™ barcode emulation is achieved using the IRBeam optical pattern generation/transmission feature. IRBeam is primarily intended for 1-D barcode transmission over IR to point-of-sale (POS) terminals. The IRBeam engine features a 1024-bit RAM for pattern storage and specialized control logic that is tailored to repetitively broadcast a barcode pattern using Page 1 Document Feedback TMG3993 − GeneralDescription the integrated LED. The IRBeam engine features adjustable timing, looping, and IR intensity to maximize successful barcode reception rate among the multitude of different barcode scanner/readers currently in use globally.
