Product details
Overview
CYAT827AZS64-22002 from Infineon Technologies is an AEC-Q100 qualified automotive-grade in-cell capacitive touchscreen controller featuring a 32-bit Arm® Cortex® CPU, 64 RX channels (2176 intersections), and support for up to ten-finger multitouch with ≤1-mm glove operation on displays up to 20-inch diagonal. It delivers 250 Hz refresh rate, integrated DSP per RX channel, and AutoArmor EMI mitigation for infotainment display systems.
For engineers reviewing the CYAT827AZS64-22002 datasheet, CYAT827AZS64-22002 pinout, CYAT827AZS64-22002 application, or CYAT827AZS64-22002 equivalent, key selection considerations include RX channel count (64), automotive temperature range (−40°C to +105°C), I²C slave interface (400 kbps), in-cell sensor architecture, and water/glove rejection capability.
Technical Context
This device implements a hybrid in-cell sensing architecture where TX/VCOM share the same layer and RX ITO resides on/above the color filter-enabling high SNR via 20-V effective drive and single-pass long-side scanning. Its dedicated ADC per RX channel and on-chip DSP accelerate touch data processing while suppressing display noise and EMI.
The controller integrates CAPSENSE® button logic, automatic baseline tracking, field-upgradable firmware via bootloader, and Android driver support. Configuration-dependent performance includes 5.3-mm electrode pitch, 16:10 aspect ratio support, and small-finger detection down to 5 mm.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RX Channels | 64 independent channels with dedicated ADCs enabling single-pass long-side scanning and parallel noise filtering. |
| Touch Points | Up to 10 simultaneous touches with fingernail tracking and large-object rejection logic. |
| Refresh Rate | Configurable up to 250 Hz-critical for low-latency response in automotive HUD and center-stack interfaces. |
| Operating Temp | −40°C to +105°C (Automotive-S grade), validated per AEC-Q100 Grade 2 for under-hood-adjacent infotainment modules. |
| Supply Voltages | 1.71–1.95 V (core), 3.0–5.5 V (I/O & analog)-supports dual-rail integration with display power domains. |
| Interface | I²C slave at 100/400 kbps-compatible with standard automotive SoC host controllers without custom PHY. |
| Power Consumption | 30 mW average-enables thermal-constrained designs in sealed dashboard enclosures. |
Pinout & Package

|---|---|---|
| VDDIO | Digital I/O supply | 3.0–5.5 V rail powering GPIO, I²C pins, and CAPSENSE® digital logic. |
| VDDA | Analog supply | 3.0–5.5 V dedicated rail for RX ADCs and analog front-end-requires local decoupling for SNR integrity. |
| VCC | Core supply | 1.71–1.95 V for Arm® Cortex® CPU and digital subsystem-tight regulation required for clock stability. |
| SCL / SDA | I²C interface | Open-drain bidirectional bus pins supporting 400 kbps-internal pull-ups disabled by default per automotive EMC requirements. |
| RESET_N | Active-low reset | Asynchronous hardware reset input synchronized internally to avoid metastability during cold cranking transients. |
| INT_N | Interrupt output | Open-drain active-low signal indicating new touch report ready-drives host interrupt controller with configurable debounce. |
Key Features
| Feature | Design Value |
|---|---|
| In-cell hybrid architecture | TX/VCOM shared layer + RX on color filter enables thinner display stacks and eliminates external sensor film in automotive LCDs. |
| AutoArmor EMI mitigation | Real-time adaptive modulation of TX waveform reduces both emissions and susceptibility-validated per CISPR 25 Class 5. |
| Water & glove rejection | Algorithmic discrimination of water droplets and ≤1-mm glove inputs without sacrificing sensitivity to bare fingers or fingernails. |
| Manufacturing test kit (MTK) | On-device self-test suite for production line validation of RX channel continuity, ADC linearity, and CAPSENSE® button functionality. |
| Android driver support | Pre-certified HAL implementation compliant with Android Automotive OS 11+ touch framework-reduces platform integration time by ≥3 weeks. |
Applications
| Infotainment Center Display | Digital Instrument Cluster |
|---|---|
Use Scenario: 12–20-inch in-dash touchscreen with ambient light variation, glove use, and condensation exposure. IC Role / Device Role / Timing Role: Primary in-cell touch controller managing all capacitive sensing, gesture decoding, and host communication. Use Value: 250 Hz refresh rate ensures <8 ms latency for swipe gestures; AutoArmor maintains SNR >45 dB in 10 V/m radiated immunity tests. | Use Scenario: Driver-facing 7–12-inch TFT cluster with safety-critical touch controls (e.g., hazard light activation). IC Role / Device Role / Timing Role: Redundant touch interface controller operating alongside primary MCU-supports ASIL-B functional safety decomposition. Use Value: −40°C to +105°C operation and AEC-Q100 qualification enable deployment in unventilated instrument housings near engine bays. |

IC Role / Device Role / Timing Role: Low-power, high-precision touch processor handling sub-5 mm finger detection and palm rejection in confined optical path. Use Value: 5 mm small-finger support and 30 mW average power allow integration into thermally isolated HUD projector modules. | Use Scenario: Rear-seat 10–15-inch entertainment tablet with multi-user gesture control and water spill resilience. IC Role / Device Role / Timing Role: Secondary touch controller offloading gesture processing from main SoC-supports independent firmware updates via bootloader. Use Value: Water rejection and 10-finger tracking enable reliable operation after beverage spills; MTK simplifies end-of-line test at contract manufacturer. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar in-cell multitouch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAIX027-64TQFP | 64 RX channels, but no AEC-Q100 qualification; max temp +85°C only; lacks AutoArmor and water rejection algorithms. | Targeted at industrial HMI-not certified for automotive safety-critical zones or harsh thermal environments. | Select only for non-automotive or cabin-zone applications where AEC-Q100 and extended temperature are not mandated. |
| ATMXT1664T-MAU | 64 RX channels, AEC-Q100 Grade 2, but uses legacy 8-bit RISC core; no integrated DSP; max refresh rate 120 Hz. | Lower computational throughput limits gesture complexity and multi-window responsiveness in modern infotainment UIs. | Consider when cost sensitivity outweighs need for 250 Hz refresh, Android HAL support, or advanced noise suppression. |
Compared with MAIX027-64TQFP and ATMXT1664T-MAU, CYAT827AZS64-22002 uniquely combines AEC-Q100 Grade 2, 250 Hz refresh, AutoArmor EMI hardening, and production-ready Android drivers-making it the only option qualified for next-generation automotive cockpit displays requiring functional safety and environmental robustness.

FAQ
Is CYAT827AZS64-22002 pin-compatible with earlier CYAT827X variants?
No. While all CYAT827X devices use the 100-pin TQFP package, pin assignments for VDDA, VDDIO, and interrupt signaling differ between A (−40°C to +85°C) and S (−40°C to +105°C) temperature grades due to internal power domain routing changes. PCB layout must be verified against the specific variant's datasheet pinout table.
Does CYAT827AZS64-22002 support SPI interface?
No. The device supports I²C slave only at 100/400 kbps. SPI is not implemented in hardware or firmware. Host communication must use I²C with appropriate slew-rate limiting and EMC filtering per Infineon's automotive layout guidelines.
What is the maximum supported electrode pitch for CYAT827AZS64-22002?
The device is characterized for 5.3-mm electrode pitch in 16:10 aspect ratio configurations. Operation beyond this pitch degrades SNR and increases false-touch probability due to reduced mutual capacitance coupling-designs exceeding 5.3 mm require full system-level validation per ISO 11452-2 and CISPR 25.
Can CYAT827AZS64-22002 operate without the bootloader?
Yes. The device ships with factory-programmed ROM bootloader, but application firmware may be loaded directly via SWD debug interface during development. Production units typically use the bootloader for field updates; disabling it is not supported and voids AEC-Q100 compliance for update-related failure modes.
