Product details
Overview
CY8CTMA616LTI-13 from Infineon Technologies is a TrueTouch capacitive touch controller IC with 16-channel analog front-end, integrated 12-bit SAR ADC, and I²C/SPI interface for single-chip touch sensing in handheld consumer devices. It supports up to 16 self-capacitance or mutual-capacitance sensors, operates from 2.7 V to 5.5 V, and features built-in noise immunity for operation near LCDs and RF sources.
For engineers reviewing the CY8CTMA616LTI-13 datasheet, CY8CTMA616LTI-13 pinout, CY8CTMA616LTI-13 application, or CY8CTMA616LTI-13 equivalent, key selection criteria include channel count, supply voltage range, interface protocol compatibility, integrated ADC resolution, and ESD tolerance in noisy portable environments.
Technical Context
The CY8CTMA616LTI-13 implements a dedicated capacitive sensing engine with programmable scan timing, automatic baseline tracking, and adaptive thresholding. Its analog front-end includes configurable charge-transfer amplifiers and correlated double sampling to suppress power-supply and LCD-induced noise.
It integrates a 12-bit successive-approximation register (SAR) ADC for digitizing sensor signals, supports both self- and mutual-capacitance measurement modes, and delivers raw data or processed gesture output via I²C (up to 400 kHz) or SPI (up to 10 MHz) interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar capacitive touch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8CMBR3116 | Same TrueTouch family, but uses CapSense CSD architecture instead of TMA; no integrated ADC | Requires external ADC for raw data processing; lower noise immunity near RF sources | Prefer when cost-sensitive and host MCU handles full signal processing |
| AT42QT2120 | Microchip QTouch IC with 12-channel capacity, 8-bit resolution, and fixed I²C-only interface | Limited to self-capacitance mode; lacks mutual-capacitance and programmable scan timing | Choose only for simple button-only UIs where channel count and resolution are secondary |
Compared with CY8CMBR3116 and AT42QT2120, the CY8CTMA616LTI-13 uniquely combines 16-channel flexibility, integrated 12-bit ADC, and dual-interface support-enabling higher-fidelity touch performance in space- and noise-constrained portable designs without external signal conditioning.

FAQ
What is the maximum number of touch sensors supported by CY8CTMA616LTI-13?
The CY8CTMA616LTI-13 supports up to 16 capacitive sensors in either self-capacitance or mutual-capacitance configuration. This is implemented via dedicated analog front-end channels with independent programmable gain and integration time, enabling simultaneous scanning of all 16 inputs without multiplexing delay.
Does CY8CTMA616LTI-13 require an external microcontroller to operate?
No. The CY8CTMA616LTI-13 contains embedded firmware that autonomously manages sensor scanning, noise filtering, baseline tracking, and gesture processing. It communicates results via I²C or SPI to a host system but does not require external code execution for basic touch detection.
Can CY8CTMA616LTI-13 drive a capacitive touchscreen with projected capacitance matrix?
Yes - it supports mutual-capacitance measurement mode, enabling full projected-capacitive (P-Cap) matrix scanning. Its 16-channel architecture can be configured as 8 transmit + 8 receive lines to resolve up to 64 intersection points, suitable for small-to-medium format touchscreens.
What is the purpose of the exposed thermal pad on the QFN package?
The exposed thermal pad on the 32-pin QFN package serves as the primary thermal conduction path to the PCB. It must be soldered to a solid copper thermal land with ≥4 thermal vias to maintain junction temperature within specification during sustained high-scan-rate operation.
