The epc611 chip is a general-purpose, monolithic, fully integrated photoelectric CMOS device for optical distance measurements and object detection. Its working principle is based on 3D TOF measurement.

The system-on-chip (SOC) contains:
• A full data acquisition path including the modulation driver for LEDs or laser diodes, the photo-receiver with an 8×8 pixel TOF CCD array, the signal conditioning, the A/D converter and the basic signal processing
• An on-chip controller managing data acquisition and data communication
• An SPI interface for the command and data communication
• A supply-voltage power management unit
