Product details
Overview
CYTMA525-48BUI25ZZT from Cypress Semiconductor is a TrueTouch® multi-touch all-points touchscreen controller featuring a 32-bit ARM Cortex™ CPU, 25 sense pins, up to 4-finger tracking, and 300-Hz refresh rate. It delivers charger noise immunity up to 60-VPP, supports wet-finger and glove operation, and targets compact touchscreens up to 3.0-inch diagonal with 4.3-mm electrode pitch.
For engineers reviewing the CYTMA525-48BUI25ZZT datasheet, CYTMA525-48BUI25ZZT pinout, CYTMA525-48BUI25ZZT application, or CYTMA525-48BUI25ZZT equivalent, key selection criteria include I²C/SPI interface compatibility, 48-ball UFBGA package constraints, analog/digital supply voltage ranges (2.65–5.5 V / 1.71–5.5 V), deep-sleep power (4.5 µW), and DualSense™ water rejection capability.
Technical Context
The CYTMA525-48BUI25ZZT implements a self-capacitive + mutual-capacitive sensing architecture with configurable TX slew rate control and external display synchronization. Its ChargerArmor™ technology enables robust operation under 60-VPP charger noise, while DualSense™ simultaneously processes self- and mutual-capacitance signals for wet-finger and large-object rejection.
It integrates an on-chip 32-bit ARM Cortex™ CPU for real-time touch processing, supports field upgrades via bootloader, and provides Android™ driver support out of box. Sensor configuration includes Manhattan, diamond, and SLIM® patterns on PET/glass substrates with LCD/AMOLED display integration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-touch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SYNAPTICS TMA388-001 | 24 sense pins; 3.3-V only analog supply; no built-in ARM CPU (requires external host processor). | Lacks integrated processing-relies on host for gesture interpretation; lower SNR in high-noise charger environments. | Choose when system already includes capable application processor and cost-sensitive BOM prioritization applies. |
| ATMEL MAXT336S | 36 sense pins; supports up to 10 touch points; 1.8-V digital supply only; no ChargerArmor™ or DualSense™. | Higher finger count but weaker wet-finger performance and no certified charger noise immunity above 30-VPP. | Prefer for larger displays (>4-inch) where multi-finger count outweighs environmental robustness requirements. |
Compared with TMA388-001 and MAXT336S, CYTMA525-48BUI25ZZT uniquely combines on-chip ARM processing, 60-VPP charger immunity, and wet-finger reliability in a 3.0-inch form factor-making it optimal for space-constrained, high-noise portable medical and industrial interfaces.

FAQ
What is the maximum supported touchscreen size for CYTMA525-48BUI25ZZT?
The device supports screens up to 3.0-inch diagonal with 4.3-mm electrode pitch and 4:3 aspect ratio. Larger sizes are possible using wider pitch layouts, but require reconfiguration of TX/RX timing and recalibration-validated up to 4.0-inch in reference designs with modified sensor stackup.
Does CYTMA525-48BUI25ZZT support both I²C and SPI simultaneously?
No-it operates exclusively in either I²C or SPI mode, selected at boot via hardware strap pins (MODE0/MODE1). Both interfaces share the same interrupt (INT) and reset (RST) signals, but cannot be active concurrently due to internal bus arbitration architecture.
How does ChargerArmor™ achieve 60-VPP immunity without external components?
ChargerArmor™ uses adaptive differential TX signaling combined with real-time noise spectrum analysis in the ARM Cortex™ firmware. It dynamically adjusts TX waveform shape and sampling phase to cancel common-mode noise before digitization-eliminating need for external chokes or RC filters.
Is the 48-ball UFBGA package lead-free and RoHS-compliant?
Yes-the CYTMA525-48BUI25ZZT uses a lead-free, halogen-free UFBGA package qualified to JEDEC J-STD-020 moisture sensitivity level 3 and compliant with EU RoHS Directive 2011/65/EU and China RoHS II.
