Product details
Overview
CYAT827AZA64-22002 from Infineon 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 thin-glove operation (≤1 mm) on displays up to 20-inch diagonal. It delivers 250 Hz refresh rate, integrated DSP for noise filtering, and AutoArmor EMI mitigation for automotive cockpit HMI systems.
For engineers reviewing the CYAT827AZA64-22002 datasheet, CYAT827AZA64-22002 pinout, CYAT827AZA64-22002 application, or CYAT827AZA64-22002 equivalent, key selection criteria include RX channel count (64), I²C slave interface (100/400 kbps), 100-pin TQFP package, -40°C to +85°C ambient range, and in-cell hybrid sensor architecture compatibility.
Technical Context
This device implements a register-configurable hybrid in-cell sensing architecture where TX/VCOM share the same layer and RX ITO resides above the color filter. Its integrated DSP enables single-pass long-side scanning across all 64 RX channels-each with a dedicated ADC-to reduce scan time and improve SNR in high-noise automotive environments.
The controller embeds AutoArmor for simultaneous EMI emission reduction and immunity enhancement, plus DualSense and CAPSENSE® button support. Water rejection, large-object rejection, automatic baseline tracking, and Android driver integration are implemented at firmware level without external components.

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 |
|---|---|---|---|
| CYAT827AZS64-22002 | Same silicon, extended temperature range (-40°C to +105°C) with higher thermal derating margin. | Required for center console modules exposed to direct sunlight or under-hood proximity. | Select when ambient operating temperature exceeds +85°C or thermal margin is critical for long-term reliability. |
| MA327001-1000 | 32-channel RX, no integrated DSP, requires external host-based filtering; lacks AutoArmor and water rejection. | Suitable only for non-AEC-Q100 interior panels with minimal EMI exposure and no glove/water requirements. | Choose only for cost-sensitive non-safety-critical applications where SNR and environmental robustness are secondary. |
Compared with CYAT827AZS64-22002, this part trades thermal headroom for lower cost and smaller thermal management overhead; versus MA327001-1000, it delivers full in-cell signal chain integration, automotive qualification, and autonomous environmental adaptation - eliminating host software dependencies.

FAQ
What is the maximum supported display size and electrode pitch for CYAT827AZA64-22002?
The device supports displays up to 20-inch diagonal with a 16:10 aspect ratio and is optimized for 5.3-mm electrode pitch. This configuration enables high-resolution touch detection while maintaining signal integrity across large in-cell panels. The 64 RX channels and dedicated ADC per channel ensure consistent SNR even at maximum physical dimensions.
Does CYAT827AZA64-22002 require external components for basic operation?
No external components are required for core functionality: integrated regulators, reference circuits, and programmable TX drivers eliminate need for discrete LDOs, op-amps, or high-voltage charge pumps. Only decoupling capacitors (per Infineon layout guidelines) and I²C pull-ups are mandatory. MTK and bootloader features operate autonomously without host firmware dependencies.
How does the device handle electromagnetic interference in automotive environments?
It employs AutoArmor - a hardware-accelerated EMI mitigation suite that dynamically adjusts TX waveform shape, timing, and amplitude to suppress both conducted and radiated emissions while simultaneously enhancing immunity to broadband RF noise (100 MHz–2 GHz). This is implemented entirely in analog/digital front-end, requiring no host CPU cycles.
Is Android driver support provided out-of-the-box?
Yes - Infineon provides a certified Android HAL (Hardware Abstraction Layer) driver compatible with Android 9 through 13, including kernel modules, user-space daemons, and gesture engine libraries. The driver supports standard Android Input Framework APIs and integrates with Android's built-in water/glove detection policies without modification.
