CPT007B-A02-GMR

Overview

The CPT007B-A02-GMR is a capacitive touch sensor controller from the TouchXpress family, designed to replace mechanical buttons without firmware development. It supports up to seven capacitive sensor inputs and features seven general-purpose outputs for host communication or LED driving. The device operates within a voltage range of 1.8 V to 3.6 V and functions between -40 °C and +85 °C. Power consumption is specified at 200 µA in active mode and 1 µA in sleep mode. It utilizes a 3 mm x 3 mm QFN package with a height of 0.55 mm.

Feature Summary

Eliminates firmware complexity by providing a fixed-function solution for capacitive touch interfaces
Includes advanced moisture immunity and wake-on-proximity capabilities for reliable operation
Configurable via a simple GUI-based tool rather than code development
Supports buzzer feedback integration to enhance user experience

Applications

Home appliances
Instrument and control panels
White goods
Medical equipment
Lighting control systems

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging details, as variations exist between tape-and-reel and tray formats. Confirm current lifecycle status, as some variants are marked obsolete. Ensure compatibility with existing design parameters before procurement.

Selection Notes

Select this component when minimizing development time is critical due to its no-firmware requirement. Evaluate power constraints carefully, noting the low sleep current. Verify that the seven-input capacity meets interface needs. Check environmental ratings for high-humidity applications given the moisture immunity feature.

Part Context

This part belongs to the Silicon Labs TouchXpress family of fixed-function controllers. It serves as an alternative to programmable microcontrollers for simple touch interfaces. The series includes variants like the CPT112S. These devices target rapid UI implementation in consumer and industrial electronics.

Replacement Considerations

Check for direct substitutes within the TouchXpress family. Verify pinout and package compatibility if considering alternatives. Review lifecycle notices for end-of-life status on similar SKUs.
