Product details
Overview
CYT2CL7BAAQ0AZSGST from Infineon is a dual-core automotive microcontroller featuring an Arm® Cortex®-M4F CPU (160 MHz max) and Cortex®-M0+ CPU (100 MHz max), integrated CAN FD (up to 8 Mbps), 4160 KB code-flash with RWW, and ASIL-B functional safety compliance. It targets cluster entry units requiring secure, low-power, real-time control with LCD and audio subsystems.
For engineers reviewing the CYT2CL7BAAQ0AZSGST datasheet, CYT2CL7BAAQ0AZSGST pinout, CYT2CL7BAAQ0AZSGST application, or CYT2CL7BAAQ0AZSGST equivalent, key selection criteria include dual-CPU partitioning for safety-critical tasks, FOTA-ready flash architecture, crypto engine support (AES-256, ECC, SHA-512), and automotive-grade power mode sequencing (Hibernate, DeepSleep, Low-power Sleep).
Technical Context
The device implements hardware-enforced inter-processor communication between M4F and M0+ cores, enabling secure peripheral management and isolation of safety-critical firmware. Its memory subsystem includes SECDED ECC on all SRAM and flash, SMPU/PPU for peripheral access control, and dual-bank flash supporting atomic firmware updates.
Clock architecture integrates IMO, ILO, ECO, WCO, PLL, FLL, and LPECO sources with CSV supervision; the LCD controller supports Type A/B waveforms and operates down to DeepSleep mode with digital contrast control. The sound subsystem delivers five SG interfaces and one PCM mixer with five input streams.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K344UAT0VLQY | NXP S32K3 series with Arm® Cortex®-M7 + M33 dual-core; higher CPU frequency (320 MHz M7), but no integrated LCD controller or CXPI | Better suited for high-performance motor control or radar preprocessing; lacks native segmented LCD drive capability | Select when prioritizing compute throughput over display integration and automotive local networking (CXPI) |
| TC397XP-128F300S-DC | Infineon AURIX™ TC3xx with TriCore™ cores (300 MHz); stronger ASIL-D capability and lockstep core redundancy, but no M0+/M4F asymmetric partitioning | Targeted at steering/braking ECUs requiring lockstep validation; less optimized for cost-sensitive cluster entry units | Select when ASIL-D certification and functional redundancy outweigh flexibility in secure peripheral offload and FOTA architecture |
Compared with S32K344UAT0VLQY and TC397XP-128F300S-DC, CYT2CL7BAAQ0AZSGST uniquely balances ASIL-B safety, integrated LCD/CXPI, and dual-core firmware partitioning-making it optimal for entry-level automotive clusters where display, local networking, and secure OTA updates are mandatory.

FAQ
What power modes does CYT2CL7BAAQ0AZSGST support and how do they differ?
CYT2CL7BAAQ0AZSGST supports five power modes: Active, Sleep, Low-power Sleep, DeepSleep, and Hibernate. Active mode enables full CPU/peripheral operation at up to 160 MHz. Sleep and Low-power Sleep retain SRAM content with reduced clock gating. DeepSleep disables CPUs but maintains RTC and limited wakeup sources. Hibernate retains only 1.1-V core regulator and four dedicated pins, consuming <1 µA typical. Each mode has distinct wakeup latency and retention scope defined in Section 27.10 of the datasheet.
Does CYT2CL7BAAQ0AZSGST support secure boot with cryptographic verification?
Yes. CYT2CL7BAAQ0AZSGST implements fast secure boot using digital signature verification (RSA/ECC) and hardware-accelerated hash (SHA-256/512) and encryption (AES-256-GCM). Boot ROM validates signed firmware images stored in flash before execution, enforcing chain-of-trust integrity. The eSHE-compliant HSM provides tamper-resistant key storage and secure key derivation, meeting UNECE R155 requirements for vehicle cybersecurity management systems.
Can the LCD controller drive both segment-based and dot-matrix displays?
No. The integrated LCD controller supports only segmented displays-up to four controllers with 32 segments and four commons per controller. It does not support dot-matrix addressing or graphic RAM (GRAM) interfaces. Drive waveforms are limited to Type A (standard) and Type B (low-power) with PWM bias control and digital contrast adjustment. Dot-matrix displays require external controllers or alternative MCUs with dedicated TFT/LCDIF peripherals.
How many CAN FD channels are implemented and what transceiver compatibility is required?
CYT2CL7BAAQ0AZSGST integrates four fully independent CAN FD controllers compliant with ISO 11898-1:2015 and Bosch CAN FD v1.0. Each requires an external CAN FD transceiver (e.g., Infineon TLE9251VS, NXP TJA1057xFD). Physical layer data rate is limited by transceiver capability and bus topology-not by the MCU-supporting up to 8 Mbps with compatible transceivers and proper termination.
