ST extends time-of-flight sensor portfolio

28 October 2020

ST Microelectronics has extended its portfolio of FlightSense time-of-flight (ToF) sensors including a 64-zone device.

The 64-zone device comprises a 940 nm vertical cavity surface emission laser (VCSEL) light source, a system-on-chip sensor integrating a VCSEL driver, the receiving array of single photon avalanche diodes (SPADs) and a 32 bit MCU core and accelerator.

The VL53L5 retains the Class 1 certification of ST’s other FlightSense sensors and is fully eye-safe for consumer products. The sensor contains optical elements in the receive aperture that create 64 ranging zones, unlocking a host of new features and use cases.

The VL53L5 sensor uses the 40 nm SPAD production process in the Crolles, France, wafer plant and assembly of all the module components were made in the back-end plants in Asia.
