Overview
The CYAT61658-64AA48 is a capacitive slider controller from Infineon Technologies, part of the TrueTouch family. It integrates an Arm Cortex CPU for advanced signal processing. The device operates on a supply voltage range of 1.71 V to 5.5 V with a typical operating current of 20 mA. It supports I2C and SPI interfaces for system communication. The component is housed in a TQFP-64 package suitable for surface mount technology. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrated Arm Cortex CPU for programmable touch sensing
- Supports I2C and SPI communication interfaces
- Capacitive slider controller architecture
- Wide supply voltage range (1.71 V to 5.5 V)
Applications
- Capacitive slider applications requiring integrated processing
- Consumer electronics with touch interface controls
- Industrial control panels using slider inputs
Procurement Notes
Verify order quantities against manufacturer specifications, as standard packaging may require multiples of 1600 units. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Check current availability status directly with authorized distributors, as stock levels fluctuate. Ensure compliance with RoHS directives if required by the target market regulations.
Selection Notes
Select this model when a dedicated capacitive slider controller with embedded processing capabilities is needed. The TQFP-64 package offers a balance of pin count and footprint size. Verify that the host system supports the required 1.71 V to 5.5 V supply range. Consider the 20 mA operating current for power budget calculations in battery-operated designs.
Part Context
This component belongs to the Infineon TrueTouch series, which focuses on capacitive touch solutions. The CYAT61658 variant specifically targets slider form factors. It shares architectural similarities with other members like the CYAT81658 but differs in specific configuration or packaging details. The integration of the Cortex CPU allows for complex gesture recognition without external microcontrollers.
Replacement Considerations
The CYAT81658-64AA48 is a related member of the same family with similar electrical characteristics and package type. Verify functional compatibility before substitution, as internal firmware or specific sensor configurations may differ between these part numbers.
