The MTCH3380P supports up to 64 mutual-capacitance or 38 self-capacitance keys, while the MTCH3240P supports up to 32 or 24 keys respectively. Both use 12 on-chip ADCs for parallel sensing, work through thick cover materials and gloves, and meet IEC/UL 60730 Class B functional safety requirements. They include AES-128 encryption, firmware authentication, I2C host interfaces, and are configurable via Microchip's mTouch Studio with Linux and Zephyr drivers. Evaluation boards EV-MTCH3380P-DEV-PCB and EV-MTCH3240P-DEV-PCB are also available, with chip pricing starting at $0.84-$1.1 per unit at 5000-piece order quantities. ## Full article daily.dev links to this article rather than hosting it.

The MTCH3380P supports up to 64 mutual-capacitance keys or 38 self-capacitance keys, plus up to 8 groups of sliders or wheels. It uses 12 on-chip ADCs for parallel sensing to improve response time and noise immunity, works through glass up to 6mm or plastic up to 3mm, and supports touch detection through gloves. _Engineers scoping touch-button HMI designs can track new controller releases like this one on daily.dev._ ### What is the difference between the Microchip MTCH3240P and MTCH3380P touch controllers? The MTCH3240P is the smaller variant, supporting up to 32 mutual-capacitance or 24 self-capacitance keys and 6 slider/wheel groups in a 38-pin XQFN package, versus the MTCH3380P's 64/38 keys, 8 groups, and 56-pin XQFN package. Only the MTCH3380P includes a PWM output for backlight, buzzer, or haptic feedback and an internal voltage doubler for 6.6V sensor drive. _Comparing touch controller specs side by side helps when picking between parts, something daily.dev readers track closely._ ## Similar posts on daily.dev - [Getting To Know The TP223 Capacitive Touch Sensor](https://daily.dev/posts/getting-to-know-the-tp223-capacitive-touch-sensor-vnlb13vth) · Hackaday · 0 upvotes · 0 comments - [A fully integrated 4.3-inch ESP32-P4 and ESP32-C5 touch display devkit](https://daily.dev/posts/a-fully-integrated-4-3-inch-esp32-p4-and-esp32-c5-touch-display-devkit-ycwxnepf0) · CNX Software · 1 upvotes · 0 comments - [A Custom Zigbee Touch Keypad](https://daily.dev/posts/a-custom-zigbee-touch-keypad-po4d64rsy) · Hackaday · 0 upvotes · 0 comments - [The 192 MHz WCH CH32V205 RISC-V MCU offers a 480 Mbps USB 2.0 interface](https://daily.dev/posts/the-192-mhz-wch-ch32v205-risc-v-mcu-offers-a-480-mbps-usb-2-0-interface-3gv9thd8u) · Adafruit Blog · 0 upvotes · 0 comments --- Tags: [#embedded](https://daily.dev/tags/embedded) [View this post on daily.dev](https://daily.dev/posts/microchip-mtch3380p-and-mtch3240p-capacitive-touch-controllers-support-up-to-64-buttons-with-paralle-5nuutvfmf) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Microchip MTCH3380P and MTCH3240P capacitive touch controllers support up to 64 buttons with parallel sensing","url":"https://daily.dev/posts/microchip-mtch3380p-and-mtch3240p-capacitive-touch-controllers-support-up-to-64-buttons-with-paralle-5nuutvfmf","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/microchip-mtch3380p-and-mtch3240p-capacitive-touch-controllers-support-up-to-64-buttons-with-paralle-5nuutvfmf"},"datePublished":"2026-10-13T10:35:43.252Z","dateModified":"2026-10-13T10:36:31.729Z","description":"Microchip has launched two new capacitive touch controllers, the MTCH3380P and MTCH3240P, aimed at display-free human-machine interfaces with touch buttons,...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b221cd497f541e1e2df61de228b97d7b?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b221cd497f541e1e2df61de228b97d7b?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"CNX Software","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"CNX Software","logo":"https://media.daily.dev/image/upload/s--xozLJZc---/f_auto,q_auto/v1780213507/logos/cnx-software?_a=BAMAMiWQ0","url":"https://daily.dev/sources/cnx-software"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/microchip-mtch3380p-and-mtch3240p-capacitive-touch-controllers-support-up-to-64-buttons-with-paralle-5nuutvfmf","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"embedded","timeRequired":"PT4M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"CNX Software","item":"https://daily.dev/sources/cnx-software"},{"@type":"ListItem","position":3,"name":"Microchip MTCH3380P and MTCH3240P capacitive touch controllers support up to 64 buttons with parallel sensing"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/microchip-mtch3380p-and-mtch3240p-capacitive-touch-controllers-support-up-to-64-buttons-with-paralle-5nuutvfmf#faq","mainEntity":[{"@type":"Question","name":"How many touch buttons can the Microchip MTCH3380P capacitive touch controller support?","acceptedAnswer":{"@type":"Answer","text":"The MTCH3380P supports up to 64 mutual-capacitance keys or 38 self-capacitance keys, plus up to 8 groups of sliders or wheels.
