Overview
The CY8CMBR2016 is a hardware-configurable CapSense Express controller supporting up to 16 capacitive touch buttons. It operates within a voltage range of 1.71 V to 5.5 V and functions in an industrial temperature range of –40 °C to +85 °C. The device integrates SmartSense auto-tuning, Flanking Sensor Suppression (FSS), and system diagnostics. Power consumption is as low as 20 µA per button in run mode and 100 nA in deep sleep. It features three host interface modes: Key Scan, Truth Table, and Encoded GPO.
Feature Summary
- Hardware-configurable matrix controller eliminating the need for software programming
- SmartSense auto-tuning algorithm for dynamic parameter adjustment
- Flanking Sensor Suppression for robust sensing of closely spaced buttons
- Built-in system diagnostics for production line testing
Applications
- Fire alarm control panels
- Security systems
- Door locks
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure the component source is authorized to guarantee authenticity and traceability. Cross-reference the datasheet revision with the procurement order to ensure compatibility with design specifications.
Selection Notes
Select this controller for applications requiring up to 16 buttons without firmware development. Evaluate the required host interface protocol, such as Key Scan or Truth Table, based on existing processor capabilities. Consider power constraints when choosing sensitivity settings and scan rates to optimize battery life.
Part Context
This component belongs to the Cypress CapSense Express family, now part of Infineon Technologies' portfolio. It is designed as a drop-in replacement for mechanical keypads, enabling rapid integration of capacitive touch interfaces into legacy designs.
Replacement Considerations
Direct replacements include other CY8CMBR2xxx series devices. Verify pinout compatibility and feature sets before substitution. Consult the official product selection guide for equivalent components with similar I/O counts and interface requirements.
