Product details
Overview
CYT2B97CACQ0AZSGST from Infineon is a dual-core automotive microcontroller featuring a 160-MHz Arm® Cortex®-M4F CPU and a 100-MHz Arm® Cortex®-M0+ CPU, integrated CAN FD (up to 8 channels), LIN (up to 12 channels), and CXPI (up to 4 channels), with 2112-KB code-flash, 256-KB SRAM, and hardware crypto engine supporting AES-128/192/256, SHA-256/512, and ECC for secure boot in body control unit applications.
For engineers reviewing the CYT2B97CACQ0AZSGST datasheet, CYT2B97CACQ0AZSGST pinout, CYT2B97CACQ0AZSGST application, or CYT2B97CACQ0AZSGST equivalent, this page delivers verified technical context, package-specific pin mapping, functional safety (ASIL-B) implementation details, and real-world use value for automotive embedded design and firmware-over-the-air (FOTA) updates.
Technical Context
The CYT2B97CACQ0AZSGST implements a tightly coupled dual-CPU architecture: the M4F handles primary application processing with single-cycle multiply and FPU, while the M0+ manages peripheral offload and security services including eSHE/HSM. Inter-processor communication is implemented via dedicated hardware mailbox and shared memory with SMPU enforcement.
It integrates three DMA controllers (P-DMA0: 92 channels, P-DMA1: 44 channels, M-DMA0: 4 channels), supports RWW flash operation in dual-bank mode for seamless FOTA, and delivers ASIL-B compliance through SECDED ECC on SRAM/flash, MPU/SMPU partitioning, and hardware watchdog supervision (MCWDT, WDT, CSV).
Key Specifications

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-core Arm® Cortex®-M7 (320 MHz); no M0+ companion core; includes Ethernet AVB but lacks CXPI and Smart I/O | Targets gateway/routing applications; less suitable for distributed body nodes requiring LIN/CXPI coexistence and hardware logic offload | Select when Ethernet connectivity and higher single-thread performance outweigh need for LIN/CXPI integration and Smart I/O flexibility |
| Renesas RH850/U2A | 32-bit RXv3 core (240 MHz); proprietary ISA; no Arm® ecosystem; supports CAN FD and LIN but no hardware crypto acceleration (AES/SHA/ECC) | Focused on powertrain and chassis; limited toolchain compatibility with Arm®-based development workflows | Prefer only where legacy RH850 software investment or specific ASIL-D certification path is required |
Compared with NXP S32K344 and Renesas RH850/U2A, CYT2B97CACQ0AZSGST uniquely combines dual-Arm® cores, CXPI support, Smart I/O logic blocks, and HSM-grade crypto in a single AEC-Q100 Grade 2 package - making it optimal for cost-sensitive, functionally safe body electronics with mixed-protocol communication needs.

FAQ
What is the maximum operating temperature range for CYT2B97CACQ0AZSGST?
CYT2B97CACQ0AZSGST is qualified per AEC-Q100 Grade 2, supporting continuous operation from –40°C to +105°C ambient temperature. This rating applies to the full 176-LQFP package variant and is validated across all electrical specifications including flash endurance, SRAM retention, and CAN FD timing margins under thermal stress.
Does CYT2B97CACQ0AZSGST support hardware-based secure boot?
Yes - it implements fast secure boot using digital signature verification (ECDSA with P-256 curve) and authenticated firmware loading via the integrated HSM. Boot ROM validates signed images before execution, and the crypto engine accelerates AES-GCM decryption and SHA-256 hashing without CPU intervention.
How many CAN FD channels are physically available on the 176-LQFP package?
The CYT2B97CACQ0AZSGST in 176-LQFP supports all eight CAN FD channels (CANFD0–CANFD7) with dedicated TX/RX pins mapped to package pins. Pin assignment tables in the datasheet confirm full channel availability - no multiplexing or channel reduction occurs in this package variant.
Is external RAM required for typical body control applications?
No - the integrated 256-KB SRAM with configurable retention modes eliminates need for external RAM in standard BCM, door, or lighting applications. Only memory-intensive applications like advanced graphics UI or large OTA image buffering would require external PSRAM or LPDDR, which is supported via the parallel bus interface.
