概述
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.
