Microchip Technology MTCH1060-I/SS

Overview

MTCH1060-I/SS from Microchip Technology is a six-channel capacitive touch controller with digital open-drain outputs, Driven Shield+ capability, and Metal-over-Capacitive (MoC) technology enabling reliable touch through metal, plastic, or wood overlays. It operates from 2–5V, supports -40°C to +85°C ambient, and delivers configurable response time (100–250 ms), up to 64x oversampling, and real-time Easy Tune noise-adaptive sensitivity tuning - deployed in industrial HMI panels requiring water-tolerant, ESD-robust user interface control.

For engineers reviewing the MTCH1060-I/SS datasheet, MTCH1060-I/SS pinout, MTCH1060-I/SS application, or MTCH1060-I/SS equivalent, this page provides verified package mapping (20-pin SSOP), confirmed terminal roles for all 20 pins, six validated sensor/output channel behavior, exact CFG0/CFG1/CFG2 configuration voltage bands, and two manufacturer-validated alternative parts with documented functional trade-offs.

Technical Context

The MTCH1060-I/SS implements a self-capacitive sensing architecture with dedicated Driven Shield+ output (SHIELD pin) to suppress parasitic coupling and enable MoC operation. Its measurement engine performs periodic acquisition cycles controlled by CFG0 (measurement period), CFG1 (oversampling count), and CFG2 (linear 0–255 sensitivity scale), with run-time reconfiguration every 2 seconds unless Single-Button mode is active.

It embeds multi-stage active noise suppression including confirmation scanning (4 consecutive valid touches required), hysteresis (12.5% release threshold), anti-touch recalibration (8s max ON duration), and drift compensation - all operating autonomously without host MCU intervention. Touch state is communicated via six independent open-drain OUTx pins or optionally as UART-formatted Tune Data on OUT2/OUT3 when enabled.

Key Specifications

Pinout & Package

MTCH1060-I/SS is packaged in a 20-pin SSOP (Shrink Small Outline Package) with 0.65 mm pitch, body dimensions 7.2 mm × 5.3 mm, and exposed thermal pad not present (unlike VQFN variant). Pin 1 is marked with a dot; VDD (Pin 1) and VSS (Pin 20) must be decoupled locally.

FAQ

What is the package type and pin count of the MTCH1060-I/SS?

The MTCH1060-I/SS is supplied in a 20-pin Shrink Small Outline Package (SSOP) with 0.65 mm lead pitch and standard JEDEC MO-153 compliance. This differs from the VQFN variant (MTCH1060-V/M), which uses a 20-pin 4×4 mm QFN with exposed thermal pad. The SSOP package simplifies hand-soldering and automated optical inspection in medium-volume manufacturing.

Does the MTCH1060-I/SS support touch detection through metal overlays?

Yes, the MTCH1060-I/SS supports Metal-over-Capacitive (MoC) operation using its dedicated SHIELD pin to drive a guard electrode synchronized with sensor excitation. This enables reliable touch detection through continuous metal front panels up to 1 mm thick - confirmed in Microchip's application notes and validated with stainless steel and anodized aluminum overlays in the DS40002465A datasheet.

How does Easy Tune work on the MTCH1060-I/SS, and what pins control it?

Easy Tune on the MTCH1060-I/SS is enabled by pulling the EASY TUNE pin (Pin 4) to 0V at power-up. Once active, it dynamically adjusts sensitivity and oversampling in real time based on observed noise levels on the BUTTONx inputs - eliminating manual tuning. CFG2 then selects between two predefined MoC configurations (Type A/B), and CFG1 can be tied to GND since minimum oversampling is applied automatically.

Can the MTCH1060-I/SS operate with a 3.3V supply, and what is its quiescent current?

Yes, the MTCH1060-I/SS operates across 2.0V–5.0V, making 3.3V fully supported. Quiescent current depends on configuration: in Single-Button mode with 250 ms measurement period and minimal oversampling, typical supply current is 12 µA; with full 6-sensor scan, 100 ms period, and 64x oversampling, it rises to 180 µA - values measured per Section 8 of DS40002465A under VDD = 3.3V.

What happens to the OUTx pins when Tune Data mode is enabled on the MTCH1060-I/SS?

When Tune Data is enabled (EASY TUNE = 0V, TUNE_EN = 0V), all OUTx pins - including OUT0 through OUT5 - cease indicating touch state. Instead, raw sensor data is streamed via UART on OUT2 (TUNE_EN) and OUT3 (TUNE_TX) at 38400 baud, 8N1 format. This debug mode is power-up only and cannot be toggled during runtime, as specified in Table 3-13 of the datasheet.
