The OSRAM TMF8821-1AM 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 very wide,dynamically adjustable, field of view,a multi-lens-array inside the package above the VCSEL widens up the FoI, all processing of the raw data is performed on-chip and the TMF8820/21/28 provide distance information together with confidence values on its I2C interface.

Direct ToF technology with high sensitivity SPAD detection
4x4 configurable multi-zone configuration with multi-object detection
adjustable field of view (up to 63° diagonal)
fast time-to-digital converter (TDC) architecture
sub-nanosecond light pulse
