CAP1298-1-SL-TR

CAP1298-1-SL-TR is a member of the CAP1298 capacitive touch sensor family. It is an 8-channel touch sensor with a digital interface (I2C) used to detect finger touches on up to eight keys or pads.
Key points:
- 8 touch channels with programmable sensitivity and thresholds
- I2C communication with interrupt capability
- Automatic calibration and noise robustness for reliable sensing
- Low-power operation with possible sleep/idle modes
- Variant suffixes (SL-TR) indicate a specific package/packaging: SL denotes the package type and TR indicates Tape & Reel shipping for automated assembly
Typical uses:
- Keypads, buttons, or touch-sensitive controls in consumer electronics, appliances, wearables, and IoT devices
Quick use overview:
- Connect Vdd, GND, SDA, SCL
- Attach electrode inputs to the 8 CAPx pins
- Configure via I2C registers for sensitivity, debounce, and reporting
- Read touch status from the device’s registers or via interrupts
For exact electrical specs, addressing, and programming details, consult the CAP1298 datasheet for the -SL-TR variant.

CAP1298-1-SL-TR: the "SL" is the manufacturer's package code for that CAP1298 variant and "-TR" means shipped on tape-and-reel. For the exact package type and dimensions, consult the CAP1298 datasheet.

CAP1298-1-SL-TR is a 16-pin capacitive-touch controller (8-channel). Key pin functions:
- 8 electrode inputs: SENS0–SENS7 (connect to touch pads)
- Power: VDD and VSS (GND)
- I²C interface: SDA and SCL
- Interrupt/Alert: INT (open-drain alert/interrupt output)
- Reset: RST (device reset/input)
- I²C address/config pins: ADD0, ADD1 (select device address/options)
- Misc: any manufacturer-specific pins (e.g., NC, test) occupy remaining pins
In short: 16 pins total: 8 sensor inputs + power, I²C (SDA/SCL), INT, RST, two address pins and remaining NC/test pins. For exact pin numbering and package drawing, refer to the CAP1298 datasheet.
