Product details
Overview
CYT2B95CACQ0AZEGS 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, hardware crypto engine (AES-128/192/256, SHA-256/512, ECC, TRNG), and ASIL-B functional safety certification. It targets body control units requiring CAN FD (up to 8 channels), LIN (up to 12), and CXPI (up to 4) in 12 V automotive systems.
For engineers reviewing the CYT2B95CACQ0AZEGS datasheet, CYT2B95CACQ0AZEGS pinout, CYT2B95CACQ0AZEGS application, or CYT2B95CACQ0AZEGS equivalent, this part supports secure over-the-air firmware updates via dual-bank flash, synchronized multi-ADC sampling for motor sensing, and hardware-enforced inter-processor communication between M4F and M0+ subsystems.
Technical Context
The CYT2B95CACQ0AZEGS implements a tightly coupled dual-CPU architecture: the M4F handles real-time application logic and signal processing, while the M0+ manages peripheral offload, security services (eSHE/HSM), and safe I/O control. Hardware inter-processor communication uses dedicated mailbox registers and interrupt routing, eliminating software polling overhead.
Its safety architecture includes SECDED ECC on all SRAM and flash, SMPU for shared memory partitioning, PPU for peripheral access control, and dual-threshold BOD (2.7 V / 3.0 V on VDDD/VDDA, 1.1 V on VCCD), enabling robust operation across automotive battery transients and cold-crank conditions.

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+ co-processor; includes HSE security module but lacks native CXPI support | Targeted at high-performance gateway ECU roles; requires external LIN/CXPI transceivers | Prefer when higher single-thread compute throughput is required and CXPI is not needed |
| Renesas RH850/U2A | 32-bit RH850 core (240 MHz); proprietary ISA; integrated CAN FD/LIN but no hardware crypto acceleration for ECC/SHA-512 | Used in powertrain and chassis ECUs; limited FOTA capability due to absence of RWW flash | Prefer for legacy RH850 toolchain continuity and deterministic real-time scheduling, not cryptographic agility |
Compared with NXP S32K344 and Renesas RH850/U2A, CYT2B95CACQ0AZEGS uniquely combines dual-core asymmetric processing, native CXPI, RWW dual-bank flash, and full HSM-grade crypto acceleration-making it optimal for cost-sensitive, feature-rich body domain controllers requiring secure OTA and mixed-protocol connectivity.

FAQ
What is the maximum operating frequency of the Cortex-M4F core in CYT2B95CACQ0AZEGS?
The Arm® Cortex®-M4F core operates at up to 160 MHz, confirmed in the datasheet's "Device-level specifications" section (Rev. *I, p.93). This frequency is achievable under full voltage (5.5 V) and ambient temperature (–40°C to 125°C) conditions with the internal PLL enabled and configured for maximum output. The M0+ core runs at up to 100 MHz independently.
Does CYT2B95CACQ0AZEGS support true hardware-based secure boot?
Yes. CYT2B95CACQ0AZEGS implements fast secure boot using digital signature verification (ECDSA with P-256 curve) and authenticated image loading from flash. The hardware crypto engine validates signatures before execution, and the boot ROM enforces immutable root-of-trust-documented in Section 4.1 and "Crypto Engine" features (p.2–3, Rev. *I).
How many CAN FD channels are physically implemented in the 176-LQFP package?
All CYT2B9 variants-including CYT2B95CACQ0AZEGS in 176-LQFP-support up to eight CAN FD channels. Pin assignment tables (p.23–40, Rev. *I) confirm dedicated CANFDx_TX/RX pins for channels 0–7, with full routing to external transceivers. No channel count reduction occurs in this package.
Is external RAM required for operation of CYT2B95CACQ0AZEGS?
No. CYT2B95CACQ0AZEGS integrates 256 KB of on-chip SRAM with configurable retention modes, sufficient for typical automotive body control applications. External RAM is optional and only needed for specialized use cases exceeding internal SRAM capacity-such as large OTA image buffering or extended diagnostic log storage.
