ams OSRAM TMF8829 48x32 Multi-Zone Direct Time-of-Flight Sensor

High-resolution multi-zone dToF sensing with long range and on-chip processing

The ams OSRAM TMF8829 is a fully integrated direct Time-of-Flight (dToF) sensor module delivering high-resolution multi-zone depth sensing in a compact 5.7 mm × 2.9 mm × 1.5 mm footprint. Built on SPAD, TDC, and histogram-based technology, the device provides configurable zone resolutions of 8x8, 16x16, 32x32, and 48x32, enabling flexible operation from long-range detection to high-density depth mapping.

The TMF8829 achieves sensing distances from 10 mm up to 11,000 mm with an 80° diagonal field of view (4:3 aspect ratio). All raw data processing is performed on-chip, providing accurate distance measurements with 0.25 mm resolution along with confidence levels, signal amplitude, and ambient light data via its digital interface. Internal histogram processing and peak detection enhance measurement robustness, making the sensor highly tolerant to cover-glass smudges and capable of detecting multiple objects per depth point without compromising accuracy.

Designed for high-speed data communication, the TMF8829 supports both I3C (I²C compatible) and fully featured SPI interfaces for device control and raw data streaming. A VBUS supply pin enables operation with 1.2 V, 1.8 V, or 3 V I/O supplies. Raw histogram data, including peak detection results, can be streamed to the host processor for advanced algorithm development and AI-enabled applications.

With its small module size, wide dynamic range, and high signal-to-noise ratio, the TMF8829 enables precise depth sensing in space-constrained commercial and industrial systems.
