Product details
Overview
CYT2B95CACQ0AZSGST 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) for body control unit applications.
For engineers reviewing the CYT2B95CACQ0AZSGST datasheet, CYT2B95CACQ0AZSGST pinout, CYT2B95CACQ0AZSGST application, or CYT2B95CACQ0AZSGST equivalent, this part delivers ASIL-B functional safety, hardware crypto acceleration (AES-128/192/256, SHA-256/512, ECC, TRNG), and low-power DeepSleep/Hibernate modes with multi-pin wakeup capability.
Technical Context
The device implements a tightly coupled dual-CPU architecture where the M4F handles primary real-time control and signal processing while the M0+ manages peripheral offload, security services (eSHE/HSM), and secure boot via digital signature verification. Inter-processor communication is handled in hardware with dedicated mailbox and semaphore resources.
It integrates three DMA controllers (P-DMA0: 92 channels, P-DMA1: 44 channels, M-DMA0: 4 channels), SECDED ECC on all safety-critical memories, and programmable analog subsystems including three 12-bit SAR ADCs (up to 67 external channels, 1 Msps) with synchronized sampling for motor-sense applications.

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 |
|---|---|---|---|
| NXP S32K344 | Single 240-MHz Arm® Cortex®-M7 core; no companion M0+; includes ASIL-D capable lockstep cores | Targeted at higher-ASIL domains (e.g., chassis control); lacks native CXPI and Smart I/O logic | Prefer when ASIL-D compliance and lockstep redundancy are mandatory over multi-protocol flexibility |
| Renesas RH850/U2A | 32-bit RXv3 core at 400 MHz; proprietary architecture; no Arm® ISA; integrated CAN FD and LIN but no CXPI | Used in Japanese OEMs with legacy toolchain dependencies; limited third-party RTOS support vs. Arm® ecosystem | Choose when existing RH850 software stack reuse and Japanese automotive qualification are priorities |
Compared with S32K344 and RH850/U2A, CYT2B95CACQ0AZSGST uniquely balances ASIL-B safety, multi-protocol support (CAN FD/LIN/CXPI), and Arm®-based dual-core flexibility-making it optimal for cost-sensitive, feature-rich body electronics where protocol diversity and secure FOTA are critical.
