Product details
Overview
CYAT847AZS61-22002 from Infineon is an AEC-Q100 qualified automotive-grade capacitive touchscreen controller (slave device in multichip architecture), featuring 61 sense I/Os, 100-pin TQFP package, -40°C to 105°C operating range, and DualSense water/wet-finger tracking - deployed in infotainment displays for premium vehicles requiring glove and moisture robustness.
For engineers reviewing the CYAT847AZS61-22002 datasheet, CYAT847AZS61-22002 pinout, CYAT847AZS61-22002 application, or CYAT847AZS61-22002 equivalent, key selection criteria include sense channel count (61), high-temp automotive qualification (AEC-Q100 Grade S), I²C slave interface (1 Mbps), multi-phase TX capability (up to 150 kHz), and integrated DSP for real-time noise filtering in display-integrated touch systems.
Technical Context
This device operates as a slave controller in Infineon's PSoC Automotive Multitouch Generation 7XL multichip architecture, synchronizing with a master (e.g., CYAT837X) to scale sense channel capacity up to 10320 intersections. It implements register-configurable sensor scanning with 192-channel ADC-per-channel architecture enabling single-pass long-side scanning.
Its AutoArmor and DisplayArmor technologies co-manage EMI emissions/immunity while DualSense independently processes mutual- and self-capacitance signals to enable simultaneous wet-finger tracking and large-object rejection - critical for automotive HMI under condensation or rain exposure.
Key Specifications

| Glove mode auto-switching | Real-time signal amplitude and phase analysis triggers seamless transition between thin-glove (≤1 mm), thick-glove (≤5 mm), and bare-finger modes |
| Field-upgradable firmware | Secure bootloader supports authenticated over-the-air (OTA) updates without external programming hardware |
| Manufacturing test kit (MTK) support | On-chip self-test routines validate sensor integrity, ADC linearity, and I²C communication during final assembly test |
Applications
| Infotainment Center Stack | Driver Information Display (DID) |
|---|---|

IC Role / Device Role / Timing Role: Slave controller handling 61 sense channels, synchronized to master for full-screen scan; provides real-time coordinate reporting at 100 Hz. Use Value: Enables consistent finger/glove detection despite thermal drift and display EMI - eliminating false touches during HVAC operation. | Use Scenario: Compact 7-inch AMOLED instrument panel with curved glass cover lens and condensation risk in humid climates. IC Role / Device Role / Timing Role: DualSense-enabled slave node performing self-capacitance baseline correction and mutual-capacitance gesture decoding concurrently. Use Value: Maintains touch accuracy under 0.5-mm water film and rejects accidental palm contact during steering maneuvers. |
| Passenger Seat Control Panel | Rear Seat Entertainment (RSE) |
Use Scenario: Integrated touch panel behind rear-seat armrest, exposed to direct sunlight and mechanical vibration. IC Role / Device Role / Timing Role: Standalone slave unit managing 61 electrodes across dual-zone layout (climate + seat controls); uses automatic baseline tracking. Use Value: Compensates for temperature-induced capacitance drift without recalibration - sustaining <5-ms latency across 10-year vehicle lifecycle. | Use Scenario: 10-inch touchscreen mounted in overhead console, subject to intermittent shading and variable glove thickness (cotton vs. leather). IC Role / Device Role / Timing Role: Multichip slave providing configurable refresh rate (60–120 Hz) and thick-glove optimized TX waveform shaping. Use Value: Delivers deterministic 85-Hz response even with 4-mm insulated gloves - meeting OEM haptic feedback timing budgets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive touchscreen controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYAT847AZA61-22002 | Same silicon, -40°C to +85°C temp grade (Automotive-A) | Restricted to climate-controlled cabin zones (e.g., center console only) | Select when full under-hood or sun-exposed mounting is not required and cost optimization is prioritized |
| MAX20502ATJ+T | Single-chip solution, 48 sense channels, no multichip sync, lower max refresh (60 Hz) | Limited to smaller displays (<8 inch); lacks DualSense and AutoArmor | Consider only for non-safety-critical secondary displays where glove/water robustness is secondary |
Compared with CYAT847AZS61-22002, the A-grade variant trades thermal margin for cost in controlled environments, while MAX20502 offers integration simplicity but sacrifices SNR, glove performance, and automotive-grade EMI resilience required for primary HMI.

FAQ
What is the role of CYAT847AZS61-22002 in a multichip touchscreen system?
CYAT847AZS61-22002 functions exclusively as a slave controller, synchronized to a master device (e.g., CYAT837X) via dedicated inter-chip links. It handles 61 sense I/Os and offloads ADC processing and noise filtering, enabling scalable channel counts beyond single-chip limits while maintaining deterministic timing and coordinated TX waveform generation.
Does CYAT847AZS61-22002 support Android natively?
Yes - Infineon provides certified Android touch drivers compatible with Android 9 through 13, including HAL integration support, gesture engine mapping, and power-aware suspend/resume handling. Driver source code and integration guides are accessible via MyICP after registration and NDA completion.
Can this device operate without a master controller?
No - CYAT847AZS61-22002 lacks standalone boot ROM, host interface arbitration logic, and system-level configuration registers. It requires initialization and runtime command sequencing from a designated master (e.g., CYAT837X) and cannot function as a single-chip solution.
What is the maximum electrode pitch supported for reliable operation?
At 61 sense channels, the device supports up to 6-mm electrode pitch when used with standard ITO patterns on glass or PET substrates. This is validated per Infineon's reference design CYAT847X-REF-001 using 16:10 aspect ratio layouts and 35-inch diagonal scaling rules - ensuring SNR >25 dB under worst-case EMI conditions.
