Overview
The CYAT81658-100AA48T is a capacitive slider controller from Infineon Technologies, part of the TrueTouch family. It features a 32-bit resolution and supports I2C and SPI interfaces. The device operates within a supply voltage range of 1.71 V to 5.5 V and functions between -40°C and +85°C. Housed in a TQFP-100 package for SMD/SMT installation, it is designed for precise touch sensing applications requiring high resolution and flexible communication protocols.
Feature Summary
- Capacitive Slider Controller with 32-bit resolution
- Dual interface support: I2C and SPI
- Wide operating voltage range: 1.71 V to 5.5 V
- Industrial temperature range: -40°C to +85°C
Applications
- Capacitive touch slider interfaces
- Linear position sensing systems
- Consumer electronics control panels
Procurement Notes
Verify the specific suffix AA48T against the official datasheet to confirm pinout and electrical characteristics. Check humidity sensitivity classification for proper storage and handling requirements. Confirm factory packaging quantity of 1500 units per reel for logistics planning. Ensure compatibility with the target system's I2C or SPI protocol settings before procurement.
Selection Notes
Select this component when a high-resolution (32-bit) capacitive slider solution is required. Ensure the application environment stays within the -40°C to +85°C operating temperature range. Verify that the host processor supports either I2C or SPI communication. The TQFP-100 package requires appropriate PCB footprint design for surface mount assembly.
Part Context
This part belongs to the CYAT8165x series of TrueTouch controllers. It is specifically categorized as a Capacitive Slider Controller within the Touch Screen Controllers product line. The manufacturer is Infineon Technologies, and it falls under the Data Converter ICs sub-category.
Replacement Considerations
Consult the official cross-reference list for verified substitutes. Generic replacements may not match the 32-bit resolution or specific interface configurations. Verify package compatibility (TQFP-100) and electrical parameters before substitution.
