CAP1166-1-CZC-TR

Overview

The CAP1166-1-CZC-TR is a capacitive touch sensor IC featuring six individual sensor inputs and six LED drivers. It operates on a 3V to 3.6V supply with typical standby current of 50µA and deep sleep current of 5µA. The device supports SMBus/I2C and SPI interfaces, offering programmable sensitivity, automatic recalibration, proximity detection, and multiple button pattern recognition. It is housed in a 20-pin 4mm x 4mm QFN package.

Feature Summary

Six capacitive touch sensor inputs with programmable sensitivity and automatic recalibration
Six LED driver outputs supporting full-on/off, blinking, dimming, and breathing controls
Multiple communication interfaces including SMBus/I2C and SPI with pin-selectable protocols
Low power operation with dedicated wake output flags for low power states

Applications

Desktop and Notebook PCs
LCD Monitors
Consumer Electronics
Appliances

Procurement Notes

Verify the specific suffix CZC against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with host controller voltage levels and interface requirements. Check for any recent product change notifications or errata sheets that may affect implementation.

Selection Notes

Select this component when six independent touch channels and LED driving capabilities are required. Consider the 20-pin QFN package for space-constrained designs. Evaluate power consumption requirements against the available standby and deep sleep modes. Verify interface compatibility with the system's microcontroller.

Part Context

The CAP1166 belongs to Microchip's RightTouch family of capacitive touch sensors. It integrates sensing algorithms and LED control into a single chip, simplifying design for multi-button interfaces. The device is designed for applications requiring reliable touch detection with minimal external components.

Replacement Considerations

Check for direct substitutes within the CAP11XX family, such as the CAP1126 or CAP1166 variants with different packages. Ensure functional equivalence in channel count, interface support, and power characteristics before substitution.
