STMicroelectronics L53L5 FlightSense time-of-flight sensor

Click2Contact

STMicroelectronics (ST) has extended its portfolio of FlightSense time-of-flight (ToF) sensors with the L53L5 — a 64-zone device that breaks a scene into separate areas to help an imaging system build a detailed spatial understanding of a scene.

The product comprises a 940 nm vertical-cavity surface-emitting laser (VCSEL) light source, a system-on-chip sensor integrating a VCSEL driver, the receiving array of single-photon avalanche diodes (SPADs) and a low-power 32-bit MCU core and accelerator running sophisticated firmware. It retains the Class 1 certification of all FlightSense sensors and is fully eye-safe for consumer products.

Housed in a miniature module, the ToF sensor contains optical elements in the receive aperture that creates 64 ranging zones. It is said to offer performance improvements in laser autofocus, touch-to-focus, presence detection and gesture interfaces, while helping developers create innovative imaging applications.

With a vertically integrated manufacturing model for its FlightSense sensors, ST builds its SPAD wafers on a 40 nm silicon process to offer 4 m ranging performance and up to 64 ranging zones, unlocking a host of features and use cases.
