Product details
Overview
CYAT827AZA64-3200A 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 10-finger multitouch with thin-glove operation (≤1 mm) on displays up to 20-inch diagonal. It integrates AutoArmor EMI mitigation, water rejection, and field-upgradable firmware via bootloader for infotainment and digital cockpit systems.
For engineers reviewing the CYAT827AZA64-3200A datasheet, CYAT827AZA64-3200A pinout, CYAT827AZA64-3200A application, or CYAT827AZA64-3200A equivalent, key selection criteria include RX channel count (64), automotive temperature range (−40°C to +85°C), I²C interface speed (up to 400 kbps), in-cell sensor compatibility, and glove/water rejection capability.
Technical Context
This device implements a hybrid in-cell architecture where TX/VCOM share the same layer and RX ITO resides above the color filter-enabling high SNR through 20-V effective drive and integrated per-channel ADCs. Its dedicated DSP performs real-time touch data filtering and baseline tracking to adapt to environmental drift.
The controller supports configurable refresh rates up to 250 Hz and delivers small-finger detection down to 5 mm using noise-suppression algorithms co-optimized with DisplayArmor and AutoArmor technologies for simultaneous EMI emission reduction and immunity enhancement.

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 |
|---|---|---|---|
| CYAT827AZS64-3200A | Same silicon, extended temp range (−40°C to +105°C) | Required for under-hood or center-stack near HVAC ducts | Select when ambient operating temperature exceeds 85°C |
| CYAT827AZA59-3200A | 59 RX channels, reduced intersection count (1856 vs. 2176) | Suitable for smaller displays (<17 inch) or lower-resolution layouts | Choose for cost-sensitive designs with <64-sensor-line requirements |
Compared with CYAT827AZA64-3200A, the S-grade variant offers higher thermal margin at identical functionality, while the 59-channel version trades intersection density for BOM cost reduction-neither is pin-compatible with alternate package types or non-TQFP variants.

FAQ
Is CYAT827AZA64-3200A pin-compatible with other CYAT827X devices in TQFP packages?
Yes-CYAT827AZA64-3200A shares identical 100-pin TQFP mechanical footprint and core power/interface pin assignments (VDDIO, VDDA, SCL/SDA, RESETn, INT) with all CYAT827X variants in the same package. However, RX/TX channel mapping and internal configuration registers differ between 59- and 64-channel versions, requiring firmware adaptation.
Does this device support SPI or UART host interfaces?
No-CYAT827AZA64-3200A provides only I²C (100/400 kbps) as its primary host communication interface. There is no native SPI or UART peripheral; external bridge ICs would be required to translate protocols, adding latency and complexity not validated by Infineon.
What is the maximum supported electrode pitch for reliable operation?
The device is characterized for 5.3-mm electrode pitch in 16:10 aspect ratio layouts, as verified in Infineon's reference designs. Operation beyond this pitch may degrade SNR and multi-touch accuracy due to increased crosstalk and reduced signal coupling-no official characterization exists for larger pitches.
Can the CYAT827AZA64-3200A perform self-test during system startup?
Yes-it includes built-in touchscreen sensor self-test functionality that validates RX/TX line continuity, capacitance range, and ADC functionality at power-on and during runtime. Results are reported via I²C register flags and can trigger diagnostic interrupts for ASIL-B–aligned system monitoring.
