Disassembly and Analysis of MEMS Ultrasonic ToF Sensor: TDK CH201
Source: Chip Learning Original Author: Chip Future The CH201 is a miniature, ultra-low power, long-range ultrasonic Time-of-Flight (ToF) distance sensor. Based on Chirp’s patented MEMS technology, the CH201 is a packaging system that integrates a PMUT (Piezoelectric Micro-Machined Ultrasonic Transducer) and an ultra-low power SoC (System on Chip), allowing the SoC to run Chirp’s advanced … Read more
