Product details
Overview
CYAT827AZA64-2200A 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 simultaneous touches 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 CYAT827AZA64-2200A datasheet, CYAT827AZA64-2200A pinout, CYAT827AZA64-2200A application, or CYAT827AZA64-2200A equivalent, key selection criteria include RX channel count (64), I²C slave interface (100/400 kbps), automotive temperature range (−40°C to +85°C), 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 above the color filter. Its dual-sense scanning engine enables single-pass long-side acquisition across all 64 RX channels, each equipped with a dedicated ADC for parallel signal digitization and noise filtering.
The embedded DSP performs real-time baseline tracking, large-object rejection, and finger/nail discrimination using configurable firmware. Host communication occurs exclusively via I²C slave interface at 100 or 400 kbps, with no SPI or UART support confirmed in documentation.

Use Scenario: Compact touch-sensitive bezels adjacent to HUD projection zones where EMI from display drivers is severe. IC Role / Device Role / Timing Role: EMI-immune touch controller leveraging AutoArmor and DisplayArmor co-design with display timing signals. Use Value: Integrated noise-suppression eliminates need for additional shielding or layout separation - reducing BOM and PCB area. | Use Scenario: Rear-seat 10–15 inch displays used with gloves, styluses, or wet fingers in family vehicles. IC Role / Device Role / Timing Role: Multi-modal touch processor supporting fingernail, thin/thick glove, and large-object rejection simultaneously. Use Value: Configurable firmware allows OEMs to tune sensitivity thresholds per seat zone without hardware change. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar in-cell touchscreen controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYAT827AZS64-2200A | Same silicon, extended temperature range (−40°C to +105°C) | Required for under-hood or powertrain-proximate mounting locations | Select when operating ambient exceeds +85°C or thermal derating margin is insufficient |
| MTCH6302-I/SS | Microchip 64-channel controller; no Arm core, no AutoArmor, max 120 Hz refresh | Lacks integrated DSP and automotive EMI hardening - suited for non-critical interior panels | Choose only if cost sensitivity outweighs AEC-Q100 compliance and SNR requirements |
Compared with CYAT827AZA64-2200A, the AZS64 variant adds thermal headroom without functional trade-offs, while the MTCH6302 offers lower integration and reduced noise immunity - making it unsuitable for primary infotainment but viable for secondary controls.

FAQ
Is CYAT827AZA64-2200A pin-compatible with earlier CYAT827X generation devices?
No. CYAT827AZA64-2200A uses a 100-pin TQFP package with specific power domain partitioning (VDDIO_0–VDDIO_3, VDDA, VDDCORE) and I²C-only interface - previous generations used different pinouts, voltage schemes, and included SPI support. Migration requires PCB redesign and firmware adaptation.
Does this device support SPI or UART host interfaces?
No. The CYAT827AZA64-2200A supports I²C slave interface only at 100 kbps or 400 kbps. There is no SPI, UART, or SDIO interface documented in the datasheet summary or ordering information - host communication must be implemented via I²C protocol stack.
What is the maximum supported electrode pitch for in-cell sensor design?
The device supports 5.3 mm electrode pitch with 16:10 aspect ratio, as specified in the datasheet summary. This pitch enables optimal SNR and scan speed balance for 20-inch diagonal displays. Deviations require validation through Infineon's CAPSENSE® tuning tools and MTK test kit.
Can the CYAT827AZA64-2200A operate without external crystal or oscillator?
Yes. The device integrates a factory-trimmed internal RC oscillator sufficient for I²C timing and touch scanning. An external crystal is optional and only required if system-level clock synchronization or tighter timing accuracy (<±1%) is needed for host co-processor alignment.
