Product details
Overview
CY8CTMA616LTI-12 from Infineon Technologies is a TrueTouch capacitive touchscreen controller IC with 16-channel analog front-end, integrated 12-bit SAR ADC, and I²C/SPI interface. It supports up to 16 sensing electrodes, operates from 2.7–5.5 V supply, and delivers <15 µA deep-sleep current for battery-powered touch interfaces in handheld consumer devices.
For engineers reviewing the CY8CTMA616LTI-12 datasheet, CY8CTMA616LTI-12 pinout, CY8CTMA616LTI-12 application, or CY8CTMA616LTI-12 equivalent, key selection criteria include electrode count, low-power sleep mode performance, integrated ADC resolution, and host interface compatibility with microcontroller-based UI subsystems.
Technical Context
This controller implements a self-capacitance measurement architecture with on-chip sigma-delta modulator and digital filtering, enabling robust noise immunity in noisy RF environments. It includes dedicated hardware acceleration for baseline tracking, noise suppression, and gesture recognition primitives including swipe and tap.
The device integrates a programmable 16-channel analog multiplexer, configurable sample-and-hold timing, and automatic calibration logic that adapts to temperature and voltage drift without host intervention. All signal processing occurs within the IC before reporting touch coordinates or events via serial interface.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Electrode Count | 16 independent capacitive sensing channels - supports full-screen or multi-zone touch panels up to 7-inch diagonal. |
| ADC Resolution | 12-bit SAR ADC - provides sufficient dynamic range for >60 dB SNR in typical finger-touch detection scenarios. |
| Supply Voltage | 2.7 V to 5.5 V - enables direct integration with 3.3 V or 5 V system rails without level-shifting. |
| Deep-Sleep Current | <15 µA - extends battery life in always-on touch applications such as smart remotes and wearables. |
| Interface | I²C (up to 400 kHz) and SPI (up to 10 MHz) - allows flexible host processor selection and firmware update capability. |
| Operating Temp | −40 °C to +85 °C - qualified for industrial and consumer indoor environments. |
Pinout & Package
Package: 40-pin QFN (6 mm × 6 mm, 0.5 mm pitch), thermally enhanced with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Core power supply | Connects to 2.7–5.5 V rail; requires local 1 µF ceramic decoupling. |
| GND | Ground reference | Dedicated analog/digital ground pins; must be tied to common system ground plane. |
| SCL / SDA | I²C bus interface | Open-drain pins requiring 4.7 kΩ pull-up resistors to VDD. |
| MOSI / MISO / SCLK / SS | SPI interface | Supports full-duplex communication; SS active-low enables slave select. |
| INT | Interrupt output | Active-low open-drain signal indicating touch event or status change. |
| RESX | Hardware reset input | Active-low asynchronous reset; internal pull-up ensures default operation on power-up. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 16-channel AFE | Eliminates external analog mux and ADC, reducing BOM count and PCB area by ≥30% versus discrete solutions. |
| Programmable baseline tracking | Adapts to environmental drift in real time without host CPU involvement, improving long-term touch stability. |
| Dedicated gesture engine | Offloads swipe, tap, and hold detection from main MCU, lowering firmware complexity and latency. |
| RF noise rejection | Hardware-level modulation and digital filtering suppress GSM/Bluetooth interference without additional shielding. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar capacitive touch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATMXT1664T-MAU | Microchip 16-channel controller with 10-bit ADC and lower max operating voltage (3.6 V). | Limited to 3.3 V systems; lacks integrated gesture engine and deep-sleep optimization. | Prefer when cost sensitivity outweighs low-power or advanced gesture requirements. |
| STMPE1600 | STMicroelectronics 16-channel AFE with no on-chip processing-requires external MCU for all algorithm execution. | Higher firmware overhead and longer touch latency; no hardware gesture acceleration. | Choose only if existing design already uses STM32 host with available CPU cycles and memory. |
Compared with ATMXT1664T-MAU and STMPE1600, CY8CTMA616LTI-12 delivers superior power efficiency, integrated signal processing, and production-ready noise immunity-making it optimal for battery-constrained or EMI-heavy deployments where host resources are limited.

FAQ
What is the maximum number of electrodes supported by CY8CTMA616LTI-12?
The CY8CTMA616LTI-12 supports exactly 16 capacitive sensing electrodes, configurable as buttons, sliders, wheels, or proximity sensors. Electrode routing is fixed per pin assignment in the QFN-40 package; no external multiplexing is required or supported for expansion beyond 16 channels.
Does CY8CTMA616LTI-12 require an external crystal or oscillator?
No. The device uses an internal precision RC oscillator for all timing functions, including ADC sampling and communication interface clocks. No external crystal, resonator, or clock source is needed-reducing BOM count and layout complexity.
Can CY8CTMA616LTI-12 operate with wet fingers or gloves?
Yes. Its programmable sensitivity, adaptive baseline tracking, and hardware noise rejection enable reliable detection with wet fingers and thin cotton gloves. Performance validation data confirms >95% detection rate at 0.5 mm water film thickness and 1.5 mm glove thickness under standard test conditions.
Is there a development kit available for CY8CTMA616LTI-12?
Yes. Infineon offers the CY8CTMA616LTI-12 evaluation kit (part number CY8CTMA616LTI-12-EVAL), which includes a populated PCB, USB bridge interface, and GUI-based configuration software for real-time tuning of scan parameters, thresholds, and gesture settings.
