Product details
Overview
TMA568-70BUI58ZZ from Cypress Semiconductor is a TrueTouch® touchscreen controller IC designed for premium smartphones and tablets, featuring 2-mm passive stylus support, palm rejection, dual-mode self- plus mutual-capacitance sensing (DualSense™), and industry-leading 40 Vpp charger noise immunity up to 500 kHz. It supports large displays (up to 8.3" at 5-mm pitch) and enables waterproof (IP-67 compliant), glove-touch, and hover-capable interfaces.
For engineers reviewing the TMA568-70BUI58ZZ datasheet, TMA568-70BUI58ZZ pinout, TMA568-70BUI58ZZ application, or TMA568-70BUI58ZZ equivalent, key selection criteria include SNR performance under display/charger noise, DualSense™ dynamic mode switching, integrated hardware DSP filtering, and support for in-cell/on-cell stackups without air gaps or shield layers.
Technical Context
The TMA568-70BUI58ZZ implements Cypress's proprietary DualSense™ architecture, enabling real-time switching between self-capacitance (for glove/hover/waterproofing) and mutual-capacitance (for multi-touch accuracy) measurement modes. Its analog front end combines narrow-band response with high-frequency sampling and on-chip hardware DSP filtering.
It features Charger Armor™ - an adaptive noise-immunity system that detects and suppresses periodic and broadband charger noise up to 40 Vpp - and external display synchronization for direct integration with LCD drivers, eliminating need for shielding or air gaps in in-cell and on-cell designs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar touchscreen controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Goodix GT9110 | Lacks hardware-based charger noise immunity >20 Vpp; relies on firmware-based filtering; no hover or 2-mm stylus support. | Suitable for mid-tier smartphones without IP-67 or stylus requirements; lower SNR limits large-screen reliability. | Select only if cost sensitivity outweighs noise immunity and advanced input modalities. |
| Atmel maXTouch MXT224E | No integrated Charger Armor™ or DualSense™; requires external components for waterproofing; max 1-mm stylus support. | Targeted at legacy designs with simpler stackups; limited to 5.5" displays and no glove/hover capability. | Consider only for backward-compatible upgrades where hover, glove, and IP-67 are not required. |

FAQ
What display stackup types does TMA568-70BUI58ZZ support?
TMA568-70BUI58ZZ natively supports in-cell, on-cell, and direct-lamination stackups through its external display synchronization interface and hardware noise cancellation. It eliminates the need for shield layers or air gaps by synchronizing scan timing with LCD frame updates, enabling thinner mechanical designs and lower EMI susceptibility.
Does TMA568-70BUI58ZZ require external components for charger noise immunity?
No. Charger Armor™ is fully integrated into the TMA568-70BUI58ZZ die and operates autonomously without external filters, op-amps, or discrete noise-suppression circuitry. It adapts in real time to detect and suppress both periodic and broadband noise up to 40 Vpp, verified per EN 61000-4-6 standards.
How does DualSense™ enable waterproofing without firmware changes?
DualSense™ uses concurrent self-capacitance (for water detection) and mutual-capacitance (for touch location) measurements within a single scan cycle. The IC's hardware differentiates water droplet capacitance signatures from finger touch in real time, rejecting false events and maintaining responsiveness - all without host processor involvement or firmware updates.
Can TMA568-70BUI58ZZ be used with single-layer touch sensors?
Yes. TMA568-70BUI58ZZ is compatible with Cypress's patented Backgammon and SLIM single-layer sensor architectures. It drives these sensors using optimized TX/RX configurations and correlated scanning algorithms, delivering full multi-touch functionality while reducing sensor layer count and overall BOM cost by up to 40%.
