Product details

Overview

CYT2B97BACQ0AZSGST from Infineon is a dual-core automotive microcontroller featuring a 160-MHz Arm® Cortex®-M4F CPU and a 100-MHz Arm® Cortex®-M0+ CPU, 2112 KB code-flash with RWW support, 256 KB SRAM, and integrated CAN FD (up to 8 channels), LIN (up to 12 channels), and CXPI (up to 4 channels). It targets body control modules requiring ASIL-B functional safety, secure boot, and hardware crypto acceleration including AES-128/192/256, SHA-256/512, and ECC.

For engineers reviewing the CYT2B97BACQ0AZSGST datasheet, CYT2B97BACQ0AZSGST pinout, CYT2B97BACQ0AZSGST application, or CYT2B97BACQ0AZSGST equivalent, this part supports fine-grained power management across Hibernate/Sleep/DeepSleep modes, synchronized multi-ADC sampling for motor sensing, and hardware inter-processor communication - critical for automotive ECU firmware update, secure gateway, and real-time peripheral offload design.

Technical Context

The device implements a split-processing architecture: the M4F handles primary application logic and signal processing with FPU and MPU, while the M0+ manages peripheral arbitration, security services (eSHE/HSM), and watchdog supervision. Both cores share memory via hardware interconnect with PPU-enforced access isolation.

Its clock system integrates IMO, ILO, ECO, WCO, PLL, and FLL sources, enabling dynamic frequency scaling and fail-safe clock monitoring (CSV). Safety-critical memories employ SECDED ECC, and BOD thresholds are configurable at 2.7 V / 3.0 V (VDDD/VDDA) and 1.1 V (VCCD).

Applications

Body Control Module (BCM)

Automotive Gateway

Use Scenario: Centralized vehicle body electronics managing door locks, lighting, wipers, and HVAC via CAN FD and LIN networks.

IC Role / Device Role / Timing Role: Primary controller executing real-time BCM firmware, coordinating LIN slaves, and routing CAN FD messages between domains.

Use Value: Dual-core architecture isolates safety-critical LIN protocol stack (M0+) from application logic (M4F), reducing certification effort and improving fault containment.

Use Scenario: In-vehicle network bridge aggregating CAN FD, LIN, and CXPI traffic between domain controllers and infotainment systems.

IC Role / Device Role / Timing Role: Secure message router with hardware crypto acceleration for OTA firmware signing and encrypted inter-domain communication.

Use Value: Integrated HSM and eSHE eliminate need for external secure element, reducing BOM count and PCB footprint while meeting UNECE R155 compliance requirements.

Electric Power Steering (EPS) Sensor Hub

Advanced Lighting Control Unit

Use Scenario: Motor position and torque sensing subsystem collecting resolver, Hall, and current feedback for EPS ECU.

IC Role / Device Role / Timing Role: Real-time sensor fusion node performing synchronized 3-ADC sampling, PWM generation, and CAN FD reporting.

Use Value: Hardware-synchronized ADCs and TCPWM blocks ensure sub-microsecond timing alignment between sampling and motor phase control - critical for torque ripple reduction.

Use Scenario: Adaptive LED headlight driver managing pixel-level dimming, thermal monitoring, and diagnostics across multiple LED strings.

IC Role / Device Role / Timing Role: High-resolution PWM generator with dead-time control and temperature-compensated current regulation via SAR ADC feedback.

Use Value: 75× TCPWM blocks and 12× dedicated motor-control counters enable independent dimming of >100 LED segments with precise thermal derating based on on-die diode readings.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-core automotive microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NXP S32K344	Single 240-MHz Arm® Cortex®-M7 core; no companion M0+; includes Ethernet MAC and ASIL-D support	Better suited for high-throughput gateway or ADAS pre-processing; lacks native CXPI and LIN channel density	Select when Ethernet connectivity or ASIL-D certification is required; avoid if CXPI or >8 LIN channels are mandatory
Renesas RH850/U2A	32-bit proprietary RXv3 core; 480-MHz max; no hardware FPU; supports CAN FD but limited crypto acceleration	Strong in legacy automotive ECU replacement; weaker in secure OTA and floating-point intensive tasks	Select for cost-sensitive legacy platform migration; avoid when cryptographic agility (ECC/SHA-512) or M4F ecosystem compatibility is needed

Compared with S32K344 and RH850/U2A, CYT2B97BACQ0AZSGST uniquely balances dual-core determinism, CXPI integration, and certified crypto acceleration - making it optimal for next-gen body domain controllers where peripheral offload, secure firmware updates, and mixed-signal timing precision are co-constrained.
