The main features of VL53L0X are listed below.
• Fully integrated miniature module:
– 940 nm Laser VCSEL
– VCSEL driver
– Ranging sensor with an advanced embedded microcontroller
– 4.4 mm x 2.4 mm x 1.0 mm size
• Fast, accurate distance ranging:
– Measures absolute range up to 2 m
– The reported range is independent of the target reflectance
– Operates in high infrared ambient light levels
– Advanced embedded optical cross-talk compensation to simplify cover glass selection
• Eye safe:
– Class 1 laser device compliant with the latest standard IEC 60825-1:2014 - 3rd edition. The laser
output remains within Class 1 limits as long as the STMicroelectronics recommended device settings
are used and the operating conditions, specified in the STM32L4+ datasheets, are respected. The
laser output power must not be increased by any means and no optics used with the intention of
focusing the laser beam. Figure 15 shows the warning label for Class 1 laser products.
• Easy integration:
– No additional optics
– Single power supply
– I

C interface for device control and data transfer: I2C2 from the STM32L4S5VIT6U MCU is used
– Xshutdown (Reset) and interrupt GPIO
– Programmable I

STSAFE-A110
STSAFE-A110 is a highly secure solution that acts as a secure element, providing authentication and data
management services to a local or remote host. It consists of a full turnkey solution with a secure operating
system running on the latest generation of secure microcontrollers. STSAFE-A110 can be integrated into IoT
(Internet of things) devices, smart-home, smart-city and industrial applications, consumer electronics devices,
consumables and accessories. STSAFE-A110 can be mounted on:
• A device that authenticates to a remote host (IoT device case), the local host being used as a pass-through
to the remote server,
• A peripheral that authenticates to localhost, for example, games, mobile accessories or consumables.
