CYTMA568-56LQI44BB from Cypress Semiconductor is a multi-touch capacitive touchscreen controller featuring a 32-bit ARM Cortex™ CPU, 44 sense I/O pins, 20-V ChargerArmor™ noise immunity, DualSense™ water/wet-finger rejection, passive stylus support (1-mm), and glove tracking (up to 5-mm thickness) for 6.0-inch displays with 5-mm sensor pitch.
For engineers reviewing the CYTMA568-56LQI44BB datasheet, CYTMA568-56LQI44BB pinout, CYTMA568-56LQI44BB application, or CYTMA568-56LQI44BB equivalent, key selection criteria include mutual-capacitance architecture, I²C/SPI interface compatibility, industrial temperature range (–40°C to +85°C), QFN-56 package footprint, and integrated hover/fingernail/glove/water rejection features.
Technical Context
The CYTMA568-56LQI44BB implements a mutual-capacitance sensing architecture with configurable TX/RX channel mapping across 44 sense I/Os, supporting up to 777 node intersections (21 × 37). Its ARM Cortex™ CPU executes real-time touch processing firmware with field-upgradable bootloader support.
It integrates ChargerArmor™ circuitry for 20-VPP charger noise suppression, DualSense™ dual-frequency sensing for wet-finger discrimination, and adaptive baseline tracking for environmental drift compensation-enabling reliable operation in high-noise mobile and industrial HMI environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-touch capacitive controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATMXT224E-MAU | 224-node max, 32-pin QFN, no built-in hover or glove auto-detection | Limited to ≤5.0-inch screens; requires external firmware for wet-finger handling | Lower BOM cost where hover/glove features are non-critical |
| FT5426GQR | 44-sense I/O, 56-pin QFN, no ChargerArmor™ or DualSense™; 10-V TX only | Requires external noise filtering for USB-C chargers; no wet-finger rejection | Acceptable for low-noise consumer tablets without industrial or medical requirements |
Compared with ATMXT224E-MAU and FT5426GQR, the CYTMA568-56LQI44BB uniquely integrates ChargerArmor™, DualSense™, and auto-glove/hover in a single 44-I/O QFN package-reducing system-level noise mitigation components and eliminating host-side algorithm development for robust touch in harsh environments.

FAQ
What is the maximum supported sensor size and resolution for CYTMA568-56LQI44BB?
The CYTMA568-56LQI44BB supports up to 6.0-inch diagonal displays with 5-mm sensor pitch and 21 × 37 node configuration (777 intersections). It achieves 10-finger tracking with small-finger detection down to 4 mm and large-object rejection up to 30 mm diameter.
Does CYTMA568-56LQI44BB require external components for charger noise immunity?
No. ChargerArmor™ is fully integrated-no external filters, ferrites, or shielding are needed to achieve 20-VPP noise immunity. The IC internally synchronizes TX timing with charger ripple and applies adaptive digital filtering to suppress common-mode interference.
Can CYTMA568-56LQI44BB operate with both glass and plastic (PET) sensor substrates?
Yes. It supports Manhattan, Diamond, SLIM®, and Totem-pole sensor patterns on glass or PET substrates, as well as SOL (sensor-on-lens), on-cell, and in-cell display integrations with LCD, AMOLED, and IPS panels-including metal-mesh transparent conductors.
Is Android driver support included out-of-the-box?
Yes. Cypress provides certified Android touch drivers (HAL layer) for Android 4.4 through 10.0, including kernel modules, configuration files, and gesture engine integration-enabling plug-and-play deployment without custom driver development.
