Product details
Overview
CYAT827AZS59-3200A from Infineon Technologies is an AEC-Q100 qualified automotive-grade in-cell capacitive touchscreen controller with 59 RX channels, 32-bit Arm® Cortex® CPU, integrated DSP, and support for 10-finger multitouch with thin-glove (≤1 mm) and fingernail tracking - deployed in center-stack infotainment displays up to 20-inch diagonal.
For engineers reviewing the CYAT827AZS59-3200A datasheet, CYAT827AZS59-3200A pinout, CYAT827AZS59-3200A application, or CYAT827AZS59-3200A equivalent, key selection criteria include its 100-pin TQFP package, -40°C to 105°C automotive-S temperature range, I²C slave interface (100/400 kbps), water rejection capability, and AutoArmor EMI mitigation architecture.
Technical Context
This device implements a hybrid in-cell sensor architecture where TX/VCOM share the same layer and RX ITO resides on/above the color filter, enabling high-density electrode pitch (5.3 mm) and 16:10 aspect ratio support. It integrates 64 RX channels (configured to 59 active in this variant), each with a dedicated ADC, allowing single-pass long-side scanning for low-latency touch reporting.
The embedded 32-bit Arm® Cortex® CPU executes register-configurable firmware with field-upgradable bootloader support, while the integrated DSP offloads real-time noise filtering, baseline tracking, and gesture processing - reducing host CPU load and enabling refresh rates up to 250 Hz under optimized configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RX Channels | 59 active receive channels - enables high-resolution touch sensing on large-area in-cell panels with up to 2176 intersections. |
| CPU Core | 32-bit Arm® Cortex® - provides real-time firmware execution for gesture recognition, environmental adaptation, and system-level control. |
| Refresh Rate | Up to 250 Hz - supports responsive user interaction in automotive HMI applications requiring sub-4-ms latency. |
| Supply Voltages | 1.71–1.95 V (logic), 3.0–5.5 V (I/O & analog) - accommodates dual-rail automotive power domains with robust noise immunity. |
| Operating Temp | -40°C to +105°C (Automotive-S grade) - validated for under-hood and center-console deployment without derating. |
| Interface | I²C slave at 100/400 kbps - interoperable with standard automotive SoCs and Android-based hosts using certified drivers. |
| Power Consumption | 30 mW average - enables thermally constrained designs in sealed infotainment modules with passive cooling. |
Pinout & Package
Package: 100-pin TQFP, 14 × 14 × 1.4 mm, 0.5-mm pitch, RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO | Digital I/O supply | 3.0–5.5 V rail powering GPIOs, I²C pins, and internal logic buffers - requires local 100-nF decoupling. |
| VDDA | Analog supply | 3.0–5.5 V rail for ADCs, sensor drivers, and analog front-end - isolated from digital ground per layout guidelines. |
| VDDCORE | Core logic supply | 1.71–1.95 V rail for Arm® Cortex® CPU and digital subsystem - sensitive to ripple; needs tight regulation. |
| SCL / SDA | I²C interface | Open-drain bidirectional bus pins supporting 100/400 kbps - require external 2.2-kΩ pull-ups to VDDIO. |
| RESETn | Active-low reset | Asynchronous hardware reset input - asserted low for ≥10 µs to initialize firmware and sensor calibration state. |
| INT | Interrupt output | Open-drain signal indicating touch event readiness - triggers host CPU interrupt on rising edge after data is available. |
Key Features
| Feature | Design Value |
|---|---|
| AutoArmor EMI mitigation | Simultaneously reduces radiated emissions and improves immunity against display switching noise and RF interference in vehicle cabins. |
| Water rejection | Distinguishes rain droplets and condensation from intentional touch via dynamic capacitance thresholding and temporal filtering. |
| Glove mode auto-switching | Automatically detects ≤1-mm glove presence and adjusts drive strength/sampling parameters without host intervention. |
| Fingernail tracking | Uses localized SNR analysis and edge-detection algorithms to resolve narrow contact points typical of fingernail use. |
| Integrated DSP | Offloads real-time baseline tracking, noise suppression, and multi-touch centroid calculation - freeing host CPU resources. |
Applications
| Center-Stack Infotainment Display | Digital Instrument Cluster |
|---|---|
Use Scenario: Touch-enabled 12–20 inch LCD display in vehicle center console with ambient light, vibration, and EMI exposure. IC Role / Device Role / Timing Role: Primary in-cell touchscreen controller managing RX/TX sequencing, raw capacitance acquisition, and gesture decoding. Use Value: Enables 10-finger swipe, pinch-to-zoom, and glove-compatible operation while maintaining <4 ms report latency under 250 Hz scan rate. | Use Scenario: Driver-facing 7–12 inch TFT cluster with safety-critical UI requiring high reliability and rapid response. IC Role / Device Role / Timing Role: Dedicated touch controller handling secondary controls (mode selection, brightness, menu navigation) independent of main display driver. Use Value: Provides fail-safe touch detection with automatic baseline drift compensation across -40°C to +105°C, eliminating false triggers during thermal cycling. |

IC Role / Device Role / Timing Role: In-cell controller supporting simultaneous child/adult touch inputs with large-object rejection and grip suppression. Use Value: Rejects palm rests and accidental presses while resolving 5 mm finger tips and fingernails - critical for shared-family interfaces. | Use Scenario: Transparent capacitive overlay on HUD combiner glass, exposed to wide temperature swings and UV radiation. IC Role / Device Role / Timing Role: Low-power, high-SNR touch sensor controller interfacing via I²C to HUD MCU with minimal board space. Use Value: Delivers 30 mW average power draw and AutoArmor EMI hardening to prevent interference with projection optics and timing-critical HUD synchronization. |
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 |
|---|---|---|---|
| CTM3200A-59 | ARM Cortex-M4 core, 59 RX channels, but lacks AutoArmor and water rejection firmware stack. | Requires external EMI filtering and custom water-handling algorithm development. | Preferred when cost sensitivity outweighs automotive EMI certification requirements. |
| CYAT827AZS64-3200A | Same architecture with 64 RX channels, identical package and temperature rating. | Supports larger panels (>17 inch) and higher intersection density (2176 vs. 1920). | Select when future panel scaling or higher resolution is planned; pin-compatible drop-in upgrade path. |
Compared with CTM3200A-59, CYAT827AZS59-3200A delivers certified EMI resilience and production-ready water/glove handling; versus CYAT827AZS64-3200A, it trades 5 extra RX channels for marginally lower BOM cost and identical footprint - ideal for fixed 15–17 inch center-stack designs.

The device supports in-cell touch panels up to 20-inch diagonal with 16:10 aspect ratio and 5.3-mm electrode pitch. Resolution is determined by RX/TX channel count and intersection density - this variant supports up to 2176 sensing nodes (59 RX × 37 TX), enabling Full HD (1920×1080) touch mapping with overscan margin.
Does CYAT827AZS59-3200A require external memory or boot ROM?
No. The device integrates 512 KB flash and 128 KB SRAM for firmware storage and runtime execution. Bootloader support enables field upgrades via I²C without external memory; all calibration data and configuration registers reside on-chip.
How does the AutoArmor feature improve EMI performance in automotive environments?
AutoArmor dynamically adjusts TX waveform shape, timing, and frequency hopping to suppress common-mode emissions from display switching noise while simultaneously enhancing receiver immunity to broadband RF interference - validated per CISPR 25 Class 5 and ISO 11452-2/4 test standards.
