Microchip has launched two turnkey capacitive touch controllers, the MTCH3380P and MTCH3240P, aimed at display-free interfaces in appliances, EV chargers and industrial gear. The pitch is parallel sensing: reading many touch sensors at once instead of one at a time. The parts are real, and priced from $0.80. Its headline regarding capacitive touch controller claims need a closer read.
What Microchip launched
The MTCH3380P supports up to 38 sensors in self-capacitance mode or 64 in mutual-capacitance mode. The MTCH3240P supports up to 24 or 32. Both use 12 on-chip analog-to-digital converters running in parallel and operate up to 105°C. They are priced from $1.06 and $0.80 respectively in 10,000-unit quantities.
Support includes the mTouch Studio development environment, with host drivers for Linux and Zephyr. Microchip targets home appliances such as ovens, cooktops and washing machines, plus outdoor equipment like EV chargers, parking meters and kiosks.
Why parallel sensing matters
Conventional touch controllers scan sensors one at a time. Add more sensors and acquisition time grows while the signal-to-noise ratio falls. That is the problem the release names, and it is a real one for interfaces that replace a display with illuminated buttons, sliders and wheels.
Microchip’s answer is 12 parallel ADCs, so many sensors are read at once. The datasheets add a patented charge-transfer acquisition engine, a choice of mutual or self-capacitance sensing, and touch-panel failure diagnostics for safety-critical features. Self-capacitance tolerates moisture; mutual capacitance allows more, denser keys.
The safety claim is “ready,” not certified
The release says the devices “support IEC/UL 60730 Class B functional safety certification.” That is a readiness claim, not a completed certification. The datasheet calls the parts “UL/IEC 60730 Class B ready.”
Certification remains the customer’s task. That distinction matters for appliance makers planning a compliance timeline. A controller that is “ready” shortens the path, but it does not deliver a certificate.
A crowded capacitive touch controller field
Microchip is not first to the capacitive touch controller market. Synaptics, Infineon (which bought Cypress and its CAPSENSE line), Goodix, FocalTech and Azoteq all compete. The top five hold more than 45% of the market.
Microchip’s edge sits in automotive and industrial segments rather than smartphones. The “first” in the release is narrower still: the first part in Microchip’s own turnkey portfolio with parallel sensing. Competitors have shipped differential and parallel sensing for years.
The timing: Microchip’s recovery
The launch lands as Microchip rebuilds. After a deep inventory correction, fiscal 2026 net sales reached $4.713 billion, up 7.1%, and the March quarter rose 35.1% year on year. The June quarter followed with $438.6 million of non-GAAP net income, and the company guides the September quarter up about 40% year on year.
New parts that cut a customer’s system cost fit that story. Microchip has paused most factory expansion and is selling a wafer fab. Revenue growth now depends on selling more silicon from the capacity it has.
What to watch
Whether the parallel-sensing design lands in volume appliance and charger designs. Whether Microchip closes the safety-certification gap or leaves it to customers. And whether $0.80 is enough to take share from Goodix and FocalTech in cost-sensitive sockets.
Editor’s Note
This analysis draws on Microchip‘s MTCH3380P and MTCH3240P release and datasheets, the company’s fiscal 2026 and fiscal 2027 results and its 10-K, Infineon’s CAPSENSE and PSoC documentation, and market research on capacitive touch controllers from Valuates, Verified Market Reports and Semiconductor Insight. Where a figure is a company’s own or an estimate, we say so.
