Product details
Overview
CYAT61652-64AA48 from Infineon Technologies is a PSoC-based TrueTouch capacitive touchscreen controller IC with 64-pin QFN package, supporting up to 20 simultaneous touch points, 12-bit resolution analog front-end, and integrated I²C/USB interface for embedded human-machine interface applications in industrial HMIs and medical displays.
For engineers reviewing the CYAT61652-64AA48 datasheet, CYAT61652-64AA48 pinout, CYAT61652-64AA48 application, or CYAT61652-64AA48 equivalent, key selection criteria include multi-touch tracking latency (<15 ms), self-capacitance + mutual-capacitance sensing architecture, operating voltage range (2.7–3.6 V), and support for wet-finger and glove operation in harsh environments.
Technical Context
The CYAT61652-64AA48 implements a dual-sensing architecture combining self-capacitance for fast single-touch detection and mutual-capacitance for precise multi-touch coordinate resolution. It integrates a 32-bit ARM Cortex-M0+ core running at 48 MHz for real-time gesture processing and firmware-defined sensor configuration.
Its analog front-end includes programmable charge-time measurement units (CTMUs) per electrode, configurable scan rates (up to 120 Hz), and hardware-accelerated noise suppression using adaptive baseline tracking and differential signal filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Touch Points | 20 simultaneous - enables complex gesture recognition (pinch-to-zoom, rotate) without coordinate aliasing |
| Interface | I²C (400 kHz) + USB 2.0 full-speed - allows direct host connection without external bridge IC |
| Supply Voltage | 2.7–3.6 V - compatible with standard 3.3 V system rails and low-power battery operation |
| Scan Rate | Up to 120 Hz - supports <15 ms end-to-end touch response time for real-time UI feedback |
| Electrode Count | 64 sensing channels - supports up to 8×8 matrix or custom segmented electrode layouts |
| Operating Temp | −40°C to +85°C - qualified for industrial and medical-grade environmental reliability |
Pinout & Package
64-pin QFN (9 mm × 9 mm, 0.5 mm pitch), thermally enhanced with exposed thermal pad. Pinout validated per Infineon's CYAT61652-64AA48 datasheet Rev. 1.3 (2022).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO | I/O supply rail | Provides 1.8–3.6 V power to digital interface pins; decoupling required within 5 mm |
| VDDA | Analog supply rail | Supplies 2.7–3.6 V to CTMU and ADC; must be filtered separately from VDDIO |
| SCL / SDA | I²C bidirectional bus | Open-drain pins requiring 2.2 kΩ pull-up to VDDIO; support standard/fast-mode timing |
| USB_DP / USB_DM | USB 2.0 differential pair | Require 90 Ω controlled impedance routing and ESD protection per USB-IF spec |
| INT | Interrupt output | Active-low open-drain signal indicating new touch data ready for host read |
Key Features
| Feature | Design Value |
|---|---|
| Wet-finger tolerance | Supports touch detection with >1 mm water layer via dynamic threshold adaptation and signal-to-noise ratio optimization |
| Glove operation | Configurable sensitivity up to 5 mm thick synthetic gloves using increased drive strength and integration time |
| Proximity wake-up | Detects finger approach within 25 mm using dedicated low-power proximity mode (15 µA typical) |
| Firmware-upgradable | Field updates via I²C or USB without hardware change; supports customer-specific gesture algorithms |

Equivalent & Alternatives
The following parts are listed as comparable options for similar capacitive touchscreen controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LQI-BL483 | Single-core Cortex-M0, no USB PHY, max 10 touch points, 48-pin QFN | Limited to smaller displays (<7″); lacks wet-finger/glove tuning firmware | Select when cost-sensitive, lower-channel-count designs omit USB connectivity |
| MTCH6302-I/SS | Microchip 16-channel controller, no ARM core, I²C-only, no firmware upgrade path | Fixed-function only; requires external MCU for gesture logic and host protocol translation | Choose for simple button/slider interfaces where programmability and multi-touch are unnecessary |
Compared with CY8C4247LQI-BL483 and MTCH6302-I/SS, CYAT61652-64AA48 uniquely combines USB-native interface, field-upgradable gesture engine, and certified wet-finger/glove operation-making it optimal for mission-critical, large-format industrial and medical touch systems requiring long-term firmware adaptability.

FAQ
What is the maximum electrode count supported by CYAT61652-64AA48?
The CYAT61652-64AA48 supports up to 64 individual sensing electrodes, configurable as a 8×8 mutual-capacitance matrix or mixed self/mutual layout. Electrode assignment is fully programmable via firmware, enabling custom shapes and asymmetric sensor grids without hardware changes.
Does CYAT61652-64AA48 require an external crystal oscillator?
No. The device integrates a factory-trimmed 48 MHz internal RC oscillator for the CPU and a separate 2 MHz precision oscillator for the analog front-end. External crystals are optional and only needed if USB suspend/resume timing or ultra-low-jitter scanning is required.
Can CYAT61652-64AA48 operate with a 1.8 V I/O supply?
Yes. VDDIO accepts 1.8–3.6 V, allowing direct interfacing with 1.8 V host processors. However, VDDA must remain within 2.7–3.6 V to maintain AFE performance; separate LDO regulation for analog and digital rails is recommended.
Is firmware source code provided for CYAT61652-64AA48?
Infineon provides full C-source firmware libraries-including touch algorithm modules, USB HID stack, and I²C driver templates-under NDA via their Developer Resources Portal. Customers retain full rights to modify, extend, and deploy compiled firmware on production units.
