Product details
Overview
CYT2B94CACQ0AZSGS 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 units.
For engineers reviewing the CYT2B94CACQ0AZSGS datasheet, CYT2B94CACQ0AZSGS pinout, CYT2B94CACQ0AZSGS application, or CYT2B94CACQ0AZSGS equivalent, this part supports ASIL-B functional safety, RWW flash updates, deep-sleep wake-up via 152 GPIOs, and dual-CPU inter-processor communication - critical for automotive ECU firmware partitioning and OTA security.
Technical Context
The CYT2B94CACQ0AZSGS implements a heterogeneous dual-CPU architecture: the M4F handles real-time control and signal processing with FPU and MPU, while the M0+ manages peripheral offload, security services (eSHE/HSM), and safe I/O handling. Hardware inter-processor communication uses dedicated mailbox registers and shared memory with SMPU enforcement.
Its peripheral set includes eight CAN FD controllers compliant with ISO 11898-1:2015 and Bosch CAN FD v1.0, twelve LIN controllers meeting ISO 17987, and four CXPI interfaces operating at 20 kbps - all routed through runtime-reconfigurable SCB blocks and protected by PPU and SECDED ECC on flash/SRAM.

Applications
| Body Control Module (BCM) | Door Module Controller |
|---|---|
|
Use Scenario: Centralized control of lighting, window lifts, locks, and mirrors in modern vehicles with CAN FD backbone communication. IC Role / Device Role / Timing Role: Primary MCU executing BCM application logic, managing LIN slaves (door modules), and coordinating secure OTA updates via HSM. Use Value: Dual-core separation isolates safety-critical lock/unlock functions (M0+) from UI rendering (M4F), while RWW flash enables silent firmware patching during vehicle idle. |
Use Scenario: Distributed door electronics controlling power windows, anti-pinch sensors, mirror positioning, and interior lighting. IC Role / Device Role / Timing Role: LIN master node interfacing with BCM over LIN bus; performs real-time motor control using TCPWM and ADC synchronized sampling. Use Value: 152 GPIOs enable direct connection to multiple switches/sensors/motors; Smart I/O blocks offload Boolean logic from CPU, reducing latency in anti-pinch response. |
| Roof Module Controller | Seat Control Unit |
|
Use Scenario: Sunroof, panoramic roof, and ambient lighting control with position feedback, tilt sensing, and RGB LED dimming. IC Role / Device Role / Timing Role: Real-time motion controller using quadrature-decoded encoder inputs and PWM-driven motor drivers; communicates via CXPI to body domain. Use Value: Up to 75 TCPWM blocks support precise multi-axis actuator timing; CXPI interface provides low-cost, noise-immune communication over long harness runs. |
Use Scenario: Motorized seat adjustment (fore/aft, recline, lumbar) with position sensing, heating, and memory recall. IC Role / Device Role / Timing Role: Dedicated motor control MCU with synchronized ADC sampling for current/voltage monitoring and closed-loop PID execution on M4F core. Use Value: Three SAR ADCs sample motor phase currents simultaneously; hardware CRC32 and TRNG ensure integrity and entropy for seat position encryption and secure memory storage. |
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 safety island and Ethernet MAC | Better suited for gateway/routing roles requiring Ethernet or higher compute density; lacks native CXPI and LIN channel count | Select when Ethernet connectivity or ASIL-D certification is required; not drop-in for LIN/CXPI-heavy body domain nodes |
| Renesas RH850/U2A | 32-bit RXv3 core (not Arm); 400-MHz peak; 12 MB flash; supports CAN FD/LIN but no CXPI or hardware crypto acceleration | Stronger legacy automotive toolchain support; limited secure boot capability vs. Infineon's eSHE/HSM integration | Prefer for brownfield projects with existing RH850 infrastructure; avoid if CXPI or FOTA security is mandatory |
Compared with NXP S32K344 and Renesas RH850/U2A, CYT2B94CACQ0AZSGS uniquely balances dual-core partitioning, CXPI support, and certified HSM-based secure boot - making it optimal for cost-sensitive, safety-aware body domain ECUs where protocol diversity and firmware update security are non-negotiable.

FAQ
What is the maximum operating temperature range for CYT2B94CACQ0AZSGS?
CYT2B94CACQ0AZSGS is qualified per AEC-Q100 Grade 2, with an operating junction temperature range of –40°C to +105°C. This rating is validated across all electrical specifications including flash programming, ADC accuracy, and CAN FD timing margins under thermal stress conditions.
Does CYT2B94CACQ0AZSGS support Over-The-Air (OTA) firmware updates?
Yes - it supports secure OTA updates via dual-bank flash architecture, Read-While-Write capability, and hardware-accelerated cryptographic verification (AES-GCM, SHA-256, ECC). The HSM enforces signature validation before execution, ensuring only authenticated firmware is loaded.
How many CAN FD channels are implemented, and what is their physical layer compatibility?
CYT2B94CACQ0AZSGS integrates eight fully independent CAN FD controllers, each compliant with ISO 11898-1:2015 and Bosch CAN FD Specification v1.0. They support data rates up to 8 Mbps and require external transceivers; no internal PHY is included.
Is debug access available after secure boot is enabled?
Yes - debug access remains available via SWD/JTAG with configurable lockdown levels. When eSHE/HSM is active, debug authentication requires valid credentials stored in secure memory; unauthenticated debug sessions are blocked by the PPU and SMPU.
