Microchip Launches High-Speed Capacitance Digitizer for Robotics
The ATFCD52 converts fine-grid capacitive sensor signals into digital data to support robotic tactile sensing.
Updated on Nov. 10, 2026 in Semiconductors
Microchip has introduced the ATFCD52, a high-speed capacitance digitizer designed for robotic tactile sensing. The device converts signals from two-dimensional capacitive sensor arrays into digital data for an external processor.
Why it matters
Tactile sensing supplies the contact information robots need to judge how firmly they hold an object and whether it is slipping. Fast acquisition could help a system adjust its grip before an object is dropped or crushed.
The ATFCD52 supports up to 52 channels in a 32 TX by 20 RX configuration, with twenty parallel on-chip analog front ends and frame rates up to 800 Hz depending on array size. It resolves capacitance changes below 1 femtofarad, though the figures are manufacturer-published and have not been independently benchmarked.
The players
Microchip
Microchip is a U.S.-based semiconductor company that designs microcontrollers, microprocessors, FPGAs and analog products for embedded control applications.
The details
The ATFCD52 acquires all receive lines simultaneously through its parallel front ends, and frequency hopping and oversampling reduce electrical noise interference. It pairs with Microchip microcontrollers, microprocessors or FPGAs, and the EV-ATFCD52 development board and ATFCD52 Configurator software support customer evaluation and real-time data logging.

The Tech Race
Capacitive sensing has long been used for touch interfaces in consumer electronics, and the ATFCD52 extends that technology toward the finer, faster arrays that robotic grippers require. The move positions Microchip among suppliers competing to supply sensing components for the growing robotics market.
Developers building robotic grippers or other tactile-sensing products may be able to evaluate capacitive sensor designs using the EV-ATFCD52 development board. The device's configuration software also lets engineers tune parameters and log data in real time.
The takeaway
Better tactile sensing could let robots handle delicate or irregular objects more reliably, which would widen their use in manufacturing and logistics. Engineers evaluating sensing hardware should weigh manufacturer-reported specifications against independent testing once it becomes available.
