The TMF8829 is a direct time-of-flight (dToF) sensor with a resolution of up to 48x32. It has a very wide field of view (FOV) of 80° and achieves a detection range of up to 11 m. The TMF8829 is a direct time-of-flight (dToF) sensor available in a small footprint modular package with an integrated Vertical Cavity Surface Emitting Laser (VCSEL). The dToF device is based on SPAD, TDC, and histogram technology and achieves a detection range of up to 11000 mm. Due to its lens on the SPAD, it supports 8x8, 16x16, 32x32 and 48x32 depth pixels and a very wide field of view. A multi-lens-array (MLA) inside the package above the VCSEL widens the FOI (field of illumination). All processing of the raw data is performed on-chip, and the TMF8829 provides distance information along with confidence values, signal amplitude, and ambient light on its interface. Internally, the TMF8829 uses dToF histograms and peak detection, and therefore, it is highly tolerant to smudges on the cover glass. Additionally, the TMF8829 can handle multiple objects per depth point simultaneously without degrading accuracy. It reports the distance of all depth points with a resolution of 0.25 mm. The device uses an I3C (I²C compatible) communication interface and a fully featured SPI interface for control and raw data streaming. A VBUS supply pin allows operation of the I²C/I3C or SPI with 1.2V, 1.8V, or 3V I/O supplies. Raw data streaming, including all algorithm results, allows further processing on the host for "AI-enabled" applications. The TMF8829 is a fully contained optical module measuring only 5.7 mm x 2.9 mm x 1.5 mm.
