Product details
Overview
CYT2B94BACQ0AZEGST 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 CYT2B94BACQ0AZEGST datasheet, CYT2B94BACQ0AZEGST pinout, CYT2B94BACQ0AZEGST application, or CYT2B94BACQ0AZEGST 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 CYT2B94BACQ0AZEGST implements a tightly coupled dual-CPU architecture: the M4F handles real-time application processing with FPU and MPU, while the M0+ manages peripheral offload, security boot, and HSM operations via dedicated inter-processor communication hardware. Memory subsystem includes SECDED ECC on all safety-critical SRAM and flash.
Its peripheral set is optimized for automotive body electronics: three DMA controllers (P-DMA0 with 92 channels, P-DMA1 with 44, M-DMA0 with 4), synchronized triple 12-bit SAR ADCs (67 total external channels, 1 Msps), and five Smart I/O blocks enabling autonomous GPIO logic without CPU intervention.

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 HSE security module but lacks integrated CXPI | Targets higher-performance gateway/routing roles; requires external transceivers for LIN/CXPI | Prefer when higher single-thread throughput is required and CXPI is not needed. |
| Renesas RH850/U2A | 32-bit RXv3 core (not Arm); 400-MHz max; supports CAN FD and LIN but no native crypto engine or RWW flash | Used in legacy Japanese OEM platforms; relies on external secure element for HSM functionality | Choose only for backward compatibility with existing RH850 toolchains and ecosystem. |
