Overview
The CG7890AA is a microcontroller unit (MCU) from Infineon Technologies, specifically designed for capacitive sensing applications. It integrates the CapSense technology to enable touch interface functionality. The component is housed in a 48-lead Quad Flat No-leads (QFN) package, which provides a compact form factor suitable for space-constrained designs. This device serves as a dedicated solution for managing capacitive touch inputs in consumer electronics and industrial control panels.
Feature Summary
- Integrates CapSense technology for reliable capacitive touch detection
- Housed in a compact 48-QFN package for space-efficient PCB layouts
- Designed specifically for microcontroller-based touch interface applications
Applications
- Capacitive touch panel controllers
- Consumer electronics with touch interfaces
- Industrial control panels requiring touch input
Procurement Notes
Verify the part status carefully, as sources indicate this specific variant may be obsolete or end-of-life. Confirm RoHS3 compliance requirements against current project specifications. Ensure the 48-QFN package footprint matches your design constraints. Cross-reference the manufacturer designation between Infineon and Cypress Semiconductor origins if sourcing from secondary markets.
Selection Notes
Select this component only if a dedicated CapSense MCU is required for the application. Evaluate the 48-QFN package size against available board real estate. Consider the obsolete status when planning long-term production runs. Verify that the integrated touch capabilities meet the specific sensor channel requirements of the target device.
Part Context
This component belongs to the family of microcontrollers specialized for human-machine interface (HMI) tasks. It combines processing capabilities with analog front-end functions for capacitive sensing. The integration reduces the need for external touch controller chips, simplifying the overall system architecture and bill of materials for touch-enabled products.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the reported obsolete status, direct replacements should be sought through official Infineon lifecycle notices or authorized distributor recommendations for equivalent newer generations.
