Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-touch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYTMA568-70BUI58CB | Adds hover detection capability beyond BB configuration | Required for proximity-aware UI (e.g., menu pre-selection before contact) | Select CB if hover-triggered UX features are mandatory; otherwise BB provides full glove/stylus/water functionality at lower cost |
| CTM5807-70BUI | Successor generation with enhanced SNR, lower power (8 mW), and extended temperature range (−40°C to +105°C) | Better suited for automotive AEC-Q200-compliant designs and extended-life industrial deployments | Choose CTM5807-70BUI for new designs targeting long-term availability and higher thermal robustness; CYTMA568-70BUI58BB remains viable for cost-sensitive consumer programs |
Compared with CYTMA568-70BUI58CB, the BB variant omits hover but retains identical glove/stylus/water performance and BGA-70 footprint; versus CTM5807-70BUI, it offers proven qualification and lower unit cost but lacks next-gen power efficiency and extended temperature rating.

FAQ
What touchscreen sensor architectures does CYTMA568-70BUI58BB support?
It supports Manhattan, Diamond, SLIM®, and Totem-pole mutual-capacitance patterns, plus Sensor-on-Lens (SOL), on-cell, in-cell, PET, glass, metal mesh, LCD, AMOLED, and IPS display stackups. The 58-sense-pin configuration enables flexible routing for single-layer FPC implementations without added interposer layers.
Does CYTMA568-70BUI58BB require external memory or firmware loading?
No. It integrates flash memory for firmware storage and boots autonomously. Field upgrades are performed via its secure bootloader using I²C or SPI-no external memory or programming hardware is needed. Android™ driver support is provided through Cypress's validated HAL integration package.
How does ChargerArmor™ differ from standard software-based noise filtering?
ChargerArmor™ uses dedicated hardware filters synchronized to charger switching frequency, operating independently of the ARM CPU. This enables real-time suppression of 100–500 kHz noise without consuming CPU cycles or increasing latency-unlike software-only methods that rely on post-processing and introduce delay or reduced reporting rates.
Can CYTMA568-70BUI58BB operate with both 1.8 V and 3.3 V host interfaces?
Yes. Its VDDIO supply accepts 1.71–5.5 V, allowing direct interfacing with 1.8 V or 3.3 V host processors. I²C and SPI I/O levels are rail-to-rail compatible, and the INT and RST pins are 5 V tolerant-eliminating level-shifters in mixed-voltage designs.
