Product details
Overview
CYAT827AZS64-2200A from Infineon Technologies is an AEC-Q100 qualified automotive-grade in-cell capacitive touchscreen controller with 64 RX channels, Arm® Cortex® CPU core, and integrated DSP for real-time touch processing. It supports up to 10-finger tracking with thin-glove (≤1 mm) and fingernail input on displays up to 20-inch diagonal, operating across -40°C to 105°C ambient range.
For engineers reviewing the CYAT827AZS64-2200A datasheet, CYAT827AZS64-2200A pinout, CYAT827AZS64-2200A application, or CYAT827AZS64-2200A equivalent, key selection criteria include RX channel count (64), I²C interface speed (400 kbps), automotive temperature grade (AEC-Q100 Automotive-S), water/glove rejection capability, and in-cell sensor architecture compatibility.
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 via 20-V effective drive and noise suppression co-designed with display timing. Its dual-sense architecture and AutoArmor technology jointly improve EMI immunity and emissions compliance in automotive cockpit environments.
The integrated 32-bit Arm® Cortex® CPU executes firmware-configurable touch algorithms, while dedicated ADC per RX channel enables single-pass long-side scanning at up to 250 Hz refresh rate. Field upgrades are supported via embedded bootloader, and manufacturing test is enabled by built-in self-test and MTK integration.

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 |
|---|---|---|---|
| CYAT827AZA64-2200A | Same silicon, Automotive-A grade (-40°C to +85°C) instead of Automotive-S | Targeted for non-under-hood, cabin-only applications with lower thermal stress | Select when full -105°C operation is not required and cost optimization is prioritized |
| MA327001-1000A | Competing 64-channel in-cell controller; lacks integrated Arm® CPU and requires external host for gesture processing | Requires additional MCU resources and firmware development for equivalent functionality | Choose only if existing platform mandates vendor lock-in or legacy driver compatibility |
Compared with CYAT827AZS64-2200A, the CYAT827AZA64-2200A reduces thermal margin but retains identical feature set and pinout, while MA327001-1000A shifts computational load to host-increasing BOM count and software validation scope.
