概要

Description

CAP1203-1-AC3-TR is a 3-channel capacitive touch sensor IC (CAP1203 family). The -TR suffix denotes Tape-and-Reel packaging. It provides three independently sensed touch inputs with a simple I²C-compatible interface, allowing adjustable sensitivity and debounce, baseline tracking, and an interrupt output to notify the host MCU of touch/release events. It operates from a single supply and is suitable for adding touch buttons to front panels, consumer electronics, appliances, and wearables. For exact electrical specs, timing, and the register map, consult the datasheet. In short, CAP1203-1-AC3-TR adds three touch-sensing inputs with easy configuration and MCU communication in a tape-and-reel package.

Features

CAP1203-1-AC3-TR is a 3-channel capacitive touch sensor controller. Key features:
- Three independent touch inputs (channels) with self-capacitance sensing
- Auto-calibration of baselines for stable operation
- Programmable sensitivity/thresholds per channel
- Debounce, noise rejection, and robust outdoor/wet-environment performance
- Interrupt output to signal touch and release events
- I2C-like two-wire serial interface for simple MCU integration
- Low-power operation with efficient power management
- Small package options and Tape & Reel (TR) shipping for automated assembly
Note: Exact supply range, register map, and timing are specified in the datasheet for CAP1203 family variants.

Pinout

- Pin count: 8 pins.
- Function: 3-channel capacitive touch sensor controller with an I2C-compatible interface. It senses touches on three electrodes (S1–S3) and reports status via I2C registers, with an interrupt output (INT). Power and ground are provided (VDD, GND). The -TR denotes tape-and-reel packaging.

Manufacturer

- Manufacturer: Microchip Technology Inc.
- What kind of company: A global semiconductor company that designs and manufactures microcontrollers, analog/interface ICs, memory, and capacitive touch sensing devices.

Application

CAP1203-1-AC3-TR is a 3-channel capacitive touch sensor suitable for replacing mechanical switches. Typical applications include:
- Consumer electronics: touch-button interfaces for remotes, audio/video players, handheld devices
- Home appliances: control panels for ovens, microwaves, coffee makers, washers/dryers
- Automotive: non-safety critical HMI controls (infotainment, climate control)
- Industrial/building automation: touch panels and equipment interfaces
- Medical devices: non-critical user input under appropriate regulatory approvals

Package

Package type: 16‑pin TSSOP (small‑outline) package, Tape‑and‑Reel (TR). The TR suffix denotes Tape & Reel packaging.
