概要

Description

The AT42QT2120-SUR is Microchip/Atmel’s QT (QTouch) capacitive touch sensor controller. It provides up to 12 self-capacitance touch channels (buttons/areas) and communicates with a host MCU via an I2C‑like serial interface. Key features include configurable sensitivity and debounce, baseline tracking, auto‑calibration, and shielding/proximity options for noise immunity. The SUR suffix denotes the surface-mount package variant (compact SOIC‑style). Typical use cases are button/keypad input for consumer devices, remotes, and control panels, especially in battery-powered products due to low power operation. For exact pinout, register map, timing, and electrical specs, see the official datasheet.

Features

Here are the key features of AT42QT2120-SUR (concise):
- 12 capacitive touch channels (buttons)
- Surface-mount SUR package
- I2C serial interface (address selectable) for config and status
- Auto-calibration with drift compensation
- Mutual-capacitance sensing with shield/guard support
- Programmable thresholds, debounce, and hysteresis
- Proximity/touch detection options and event-driven interrupts
- Wake-on-touch and low-power standby modes
- Robust noise immunity and EMI rejection
- Small footprint, RoHS-compliant
Note: exact voltage range and performance specs depend on operating conditions and device configuration.

Package

AT42QT2120-SUR is supplied in an 8-pin SOIC (surface-mount) package; the “R” denotes tape-and-reel packaging for automated assembly.

Pinout

- Pin count: 20 pins (SUR package)
- Function: Capacitive touch sensor controller (QT2120) with I2C interface, supporting up to 12 touch channels (buttons) plus VDD, GND, SDA, SCL and optional IRQ.
