Datasheet - CY8CMBR3108-LQXIT

Infineon CY8CMBR3108 Series Touch Controller IC, 1.8V Minimum Supply Voltage, 5.5V Maximum Supply Voltage - CY8CMBR3108-LQXIT

This touch controller IC provides capacitive input sensing for human-machine interfaces, converting up to eight discrete touch inputs into digital data via a serial bus. It operates across a low-voltage supply range suitable for battery-powered and embedded systems, and is supplied in a surface-mount QFN package intended for space‑constrained circuit designs. The device is intended for integration where a compact, low-power capacitive touch solution is required.

Features and Benefits:

• Operates from 1.8V to 5.5V enabling flexible power architectures
• Eight-button input handling reduces external decoder requirements
• I2C interface simplifies connection to microcontrollers
• 16-pin QFN package minimises board footprint
• 7-bit sensing resolution permits fine touch discrimination
• Rated for -40 to 85°C use suits extended temperature environments

Applications

• Ideal for low-voltage HMI panels in portable instruments
• Suitable for industrial control panels exposed to temperature extremes
• Used with embedded microcontrollers for consumer appliances
• Can be used for keypad replacement in medical devices
• Used for compact control surfaces in instrumentation enclosures

What sensing method does it use and what wiring does that require?

It employs capacitive sensing and is designed for two-wire sensor connections to the touch electrodes.

How does package selection affect assembly options?

The QFN surface-mount format enables automated soldering and short interconnects for high-density PCBs.

What thermal range can be expected during continuous operation?

The device is specified for operation down to -40°C and up to 85°C, suitable for many industrial environments.

How many pins are available for system interfacing?

A 16-pin footprint provides the necessary power, ground, I2C signals and touch input connections.
