ams TMF8820 3x3 multi-zone Time-of-Flight Sensor

The TMF8821 is a direct time-of-flight (dToF) sensor in a single modular package with associated VCSEL. The dToF device is based on SPAD, TDC and histogram technology and achieves 5000 mm detection range. Due to its lens on the SPAD, it supports 3x3, 4x4 and 3x6 multizone output data and a wide, dynamically adjustable, field of view. A multi-lens-array (MLA) inside the package above the VCSEL widens up the FoI (field of illumination). All processing of the raw data is performed on-chip and the TMF8821 provides distance information together with confidence values on its I2C interface.

The TMF8828 is a direct time-of-flight (dToF) sensor in a single modular package with associated VCSEL. The dToF device is based on SPAD, TDC and histogram technology and achieves 5000 mm detection range. Due to its lens on the SPAD, it supports 3x3, 4x4, 3x6 and 8x8 multizone output data and a wide, dynamically adjustable, field of view. A multi-lens-array (MLA) inside the package above the VCSEL widens up the FoI (field of illumination). All processing of the raw data is performed on-chip and the TMF8828 provides distance information together with confidence values on its I2C interface.

Product status: Pre-ProductionThe TMF8829 is a direct time-of-flight (dToF) sensor with configurable resolution of 8x8, 16x16, 32x32 & 48x32. The device is based on SPAD, TDC, and histogram technology and achieves a detection range of up to 11000 mm with an 80° field of view. 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 peak detection 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.

The TMF8806 is a time-of-flight (TOF) sensor in a single modular package with associated VCSEL. The TOF device is based on SPAD, TDC and histogram technology. The device achieves 500cm detection range which may be extended to 1000cm with a small firmware download.
