TMF8801-1BM

Overview

The TMF8801-1BM is a direct Time-of-Flight (dToF) sensor capable of measuring distances from 20mm up to 2500mm with an integrated Cortex-M0 core and a SPAD-based architecture. It uses a histogram-based measurement system to provide reliable distance and signal quality data even under challenging light conditions or behind cover glass.

Why Choose This Part

The sensor features a Class 1 eye-safe VCSEL and dynamic cover glass calibration to maintain 5 percent accuracy despite smudge or scratches on the protective lens. Its histogram architecture effectively filters out multi-path reflections and ambient noise, ensuring high-quality data output via the I2C interface.

Applications

Getting Started

Start development using the TMF8801-EVM evaluation kit, which connects via USB for rapid testing on a PC. For firmware integration, ams-OSRAM provides a driver library for the I2C interface to handle the histogram processing and device configuration from an external host MCU.
