CY8CMBR3155-LQXI

Overview

The CY8CMBR3155-LQXI is a capacitive touch sensor controller from the Cypress Semiconductor CY8CMBR3 series. It features a 16-pin QFN package and operates within a supply voltage range of 1.71 V to 5.5 V. The device supports up to 300 mm sensing distance and includes an integrated M8C core with 8 kB of flash memory and 1 KB of RAM. Communication interfaces include I2C and SPI, while the operating temperature range spans from -40°C to 85°C.

Feature Summary

Capacitive sensing technology for touch detection
Integrated microcontroller core with non-volatile memory
Dual communication interface support for system integration

Applications

Capacitive touch sensor applications
Embedded control systems requiring touch input
Consumer electronics with user interface requirements

Procurement Notes

Verify the specific ordering suffix against official datasheets to ensure correct package and temperature grade compatibility. Confirm RoHS compliance status through manufacturer documentation prior to procurement. Cross-reference the component number with current availability lists as product lifecycle status may affect long-term supply continuity.

Selection Notes

Select this component when a dedicated capacitive touch controller with integrated processing capabilities is required. Ensure the design accommodates the specified 1.71 V to 5.5 V supply range and utilizes either I2C or SPI for data exchange. Verify that the 16-pin QFN footprint fits the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the CY8CMBR3 family of capacitive sensing controllers by Cypress Semiconductor, now part of Infineon Technologies. These devices are designed to replace mechanical switches in modern electronic interfaces. The family integrates sensing logic and processing to reduce external component count and simplify firmware development for touch-based user interfaces.

Replacement Considerations

Check for pin-compatible alternatives within the same CY8CMBR3 series or newer generations from Infineon. Verify functional equivalence regarding sensing channels and interface protocols before substitution.
