CYTMA568-70BUI58AP

Overview

The CYTMA568-70BUI58AP is a TrueTouch multi-touch capacitive touchscreen controller featuring a 32-bit ARM Cortex CPU. It supports up to 58 sense pins with 777 intersections and reports up to 10 fingers at refresh rates up to 230 Hz. The device operates on a 1.71-V to 5.5-V digital supply and a 2.65-V to 5.5-V analog supply, consuming 12 mW average power. It includes ChargerArmor for noise immunity up to 20 V peak-to-peak, DualSense water rejection, passive stylus support, and glove tracking. Communication interfaces include I2C (up to 3.4 Mbps) and SPI (up to 8 Mbps).

Feature Summary

• Multi-touch capabilities supporting up to 10 fingers with fast first-touch response of ≤13 ms.
• Integrated ChargerArmor technology providing immunity to charger noise up to 20 volts peak-to-peak.
• DualSense technology enabling water rejection and wet-finger tracking alongside automatic glove mode switching.
• Supports passive stylus input with palm rejection and hover finger tracking.

Applications

• Smartphones and tablets requiring high-performance touch interfaces.
• Automotive infotainment systems needing reliable operation under various environmental conditions.
• Industrial control panels utilizing glove or stylus interaction.

Procurement Notes

Verify the specific suffix 'AP' against official Cypress ordering guides to confirm feature set inclusion, particularly regarding passive stylus and glove support. Ensure compatibility with the target sensor pitch and screen size constraints defined in the summary datasheet.

Selection Notes

Select this model for applications requiring robust noise immunity and advanced gesture recognition. Confirm that the system design accommodates the 70-ball BGA package dimensions and utilizes the appropriate I2C or SPI interface speeds supported by the host processor.

Part Context

This component belongs to the CYTMA568 TrueTouch family, designed as an all-points touchscreen controller. It integrates programmable logic and firmware capabilities, allowing field upgrades via bootloader and supporting various sensor patterns including Manhattan, Diamond, and SLIM configurations.

Replacement Considerations
