Product details
Overview
CYT2B94BACQ0AZSGS 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 (AES-128/192/256, SHA-256/512, ECC, TRNG).
For engineers reviewing the CYT2B94BACQ0AZSGS datasheet, CYT2B94BACQ0AZSGS pinout, CYT2B94BACQ0AZSGS application, or CYT2B94BACQ0AZSGS equivalent, this part delivers deterministic real-time control, hardware-enforced memory protection (MPU/SMPU), synchronized multi-ADC sampling for motor sensing, and low-power DeepSleep/Hibernate modes with configurable wake-up sources including GPIO, RTC, and EVTGEN timers.
Technical Context
The CYT2B94BACQ0AZSGS implements a tightly coupled dual-CPU architecture: the M4F handles primary application tasks with FPU and single-cycle multiply, while the M0+ manages peripheral offload, security services, and inter-processor communication via dedicated hardware mailbox. Its clock system integrates IMO, ILO, ECO, WCO, PLL, and FLL with dynamic frequency scaling across power modes.
Peripheral subsystems include three DMA controllers (P-DMA0: 92 channels, P-DMA1: 44 channels, M-DMA0: 4 channels), 75×16-bit + 8×32-bit TCPWM blocks supporting PWM_DT and quadrature decoding, and three SAR ADCs (12-bit, 1 Msps) with synchronized sampling and external multiplexer addressing-enabling precise motor current/voltage monitoring in automotive body electronics.

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 chassis/safety domains; requires external LIN/CXPI transceivers | Select when prioritizing raw M7 compute throughput over hardware-isolated peripheral/security processing |
| Renesas RH850/U2A | 32-bit RXv3 core (not Arm); 480-MHz max; supports CAN FD and LIN but no native CXPI; uses different crypto IP (TRUSTZONE-based) | Used in Japanese OEM powertrain systems; toolchain and ecosystem differ significantly from Arm-based workflows | Select for legacy RH850 platform continuity or where non-Arm ISA alignment is mandated |
Compared with NXP S32K344 and Renesas RH850/U2A, CYT2B94BACQ0AZSGS uniquely combines Arm dual-core determinism, native CXPI support for next-gen body networks, and hardware-synchronized triple ADC sampling-making it optimal for cost-sensitive, ASIL-B-compliant body domain controllers requiring mixed-signal precision and secure FOTA.

FAQ
What is the maximum operating frequency of the Cortex-M4F core in CYT2B94BACQ0AZSGS?
The Arm® Cortex®-M4F core operates at up to 160 MHz, verified in the device's electrical specifications (Datasheet Rev. *I, Section 27.11). This frequency is achievable under specified voltage (2.7–5.5 V) and temperature (–40°C to +125°C) conditions, with PLL clock source enabled and appropriate voltage regulator configuration.
Does CYT2B94BACQ0AZSGS support hardware-based secure boot with cryptographic verification?
Yes-it implements fast secure boot using digital signature verification (ECDSA or RSA) via its integrated Hardware Security Module (HSM). Boot image authenticity is validated against public keys stored in eFuse before execution, with AES-GCM decryption applied to encrypted firmware images loaded into flash.
How many CAN FD channels are physically implemented in the 176-LQFP package of CYT2B94BACQ0AZSGS?
All CYT2B9 variants-including the 176-LQFP CYT2B94BACQ0AZSGS-support up to eight CAN FD channels, as confirmed in the feature list (Datasheet Rev. *I, Table 1-1) and peripheral I/O map (Section 7). Each channel has dedicated TX/RX pins routed to the package's high-speed I/O banks.
Is the 256 KB SRAM in CYT2B94BACQ0AZSGS fully retained in DeepSleep mode?
No-SRAM retention is configurable per 8-KB block. In DeepSleep mode, only selected blocks retain data; full retention requires Hibernate mode. This granular control minimizes leakage current while preserving critical context (e.g., CAN message buffers or calibration data) without powering the entire memory array.
