81688-100AS61KA

Overview

The CYAT81688-100AS61KA is a capacitive touchscreen controller from Infineon Technologies, part of the TrueTouch Standard TS3xxx family. It integrates an Arm Cortex-M0 CPU and supports I2C and SPI interfaces. 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 features a 32-bit resolution and includes four ADC inputs for sensor configuration. The component is housed in a TQFP-100 package suitable for surface-mount installation and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

Integrated Arm Cortex-M0 processor for advanced touch processing
Supports both I2C and SPI communication protocols
Includes four dedicated ADC inputs for sensor tuning
Operates within a wide voltage range of 1.71 V to 5.5 V

Applications

Capacitive touch interface controllers
Industrial human-machine interfaces (HMI)
Consumer electronics touch panels

Procurement Notes

Verify the exact suffix 'KA' against official Infineon documentation, as standard listings often use 'KHT'. Confirm moisture sensitivity level (MSL) requirements for reflow soldering profiles. Check for availability constraints or long lead times associated with this specific variant. Ensure the TQFP-100 package compatibility with your PCB footprint.

Selection Notes

Select this model when a dedicated MCU is required for complex gesture recognition or custom touch algorithms. The integrated Cortex-M0 core allows for firmware updates without an external processor. Ensure the design accommodates the 100-pin TQFP package size and thermal dissipation needs for the specified operating temperature range.

Part Context

This component belongs to the CYAT81688 series, which are PSoC-based TrueTouch controllers. These devices are designed to replace discrete touch controller solutions by integrating processing power directly into the touch sensing IC. The series supports various panel sizes and electrode configurations through software programmability.
