Microchip Enhances Robotic Tactile Sensing with High-Speed Capacitance Digitizer

  • Microchip Technology introduced the ATFCD52 high-speed capacitance digitizer to convert signals from 2D capacitive sensor arrays into digital data for robotic tactile sensing.
  • The device enables external processors to calculate normal & shear forces, allowing robotic grippers to adjust grasps & prevent slipping or crushing of fragile objects.
  • It supports up to 52 channels with 32 transmit by 20 receive lines & utilizes 20 parallel analog front ends to achieve frame rates up to 800 Hz.
  • The ATFCD52 resolves capacitance changes below 1 femtofarad to detect subtle deformations in noisy electrical environments using frequency hopping & oversampling.
  • System-level processing can be paired with Microchip MCUs, MPUs, or FPGAs for applications including robotics, augmented reality, gaming accessories, & wearable electronic skin.
  • Development is supported by the EV-ATFCD52 evaluation board & ATFCD52 Configurator software for parameter configuration & real-time data logging.
  • The ATFCD52 is available for purchase directly from Microchip or through authorized worldwide distributors.
