Product details
Overview
CYT2B64BADQ0AZSGST from Infineon Technologies (formerly Cypress) is a dual-core automotive microcontroller featuring an 80-MHz Arm® Cortex®-M4F CPU with FPU and an 80-MHz Arm® Cortex-M0+ CPU for peripheral/security processing. It integrates 576 KB code-flash, 64 KB SRAM, CAN FD (up to 8 Mbps), LIN, crypto engine (AES-128/192/256, SHA-256/512, TRNG), and ASIL-B functional safety support. It targets body control units in 125 °C extended-temperature automotive systems.
For engineers reviewing the CYT2B64BADQ0AZSGST datasheet, CYT2B64BADQ0AZSGST pinout, CYT2B64BADQ0AZSGST application, or CYT2B64BADQ0AZSGST equivalent, key selection criteria include dual-CPU real-time partitioning, CAN FD timing compliance (ISO 11898-1:2015), eSHE/HSM security enablement, RWW flash update capability, and 100-LQFP package compatibility with automotive-grade thermal and voltage specs (2.7–5.5 V, –40°C to +125°C).
Technical Context
The CYT2B64BADQ0AZSGST implements hardware-enforced inter-processor communication between its M4F and M0+ cores, enabling deterministic separation of safety-critical tasks (e.g., CAN FD message filtering in M0+) from application logic (e.g., motor control PWM generation in M4F). Its three DMA controllers-P-DMA0 (54 channels), P-DMA1 (26), and M-DMA0 (2)-support concurrent peripheral-to-memory and memory-to-memory transfers without CPU intervention.
Functional safety is implemented via SMPU, PPU, SECDED ECC on SRAM/flash, dual BOD thresholds (2.7 V/3.0 V on VDDD/VDDA), and MCWDT with independent clock domains. The crypto engine delivers hardware-accelerated AES-GCM, RSA/ECC vector unit, and SHA-512-enabled only in HSM-configured variants per ordering options.

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); includes ASIL-D safety support and Ethernet MAC; lacks integrated LIN PHY | Targets higher-tier ADAS domain controllers requiring Ethernet backbone; not pin-compatible or software-compatible | Select when Ethernet connectivity and ASIL-D certification are required; avoid if LIN integration and cost-sensitive BCM design are priorities |
| Renesas RH850/U2A | Dual-core (RH850 core + safety monitor core); 40-nm process; supports CAN FD but no integrated crypto acceleration or RWW flash | Focused on powertrain and chassis control; limited analog integration (no triple synchronized ADC) | Prefer for high-reliability powertrain applications where functional safety dominates over security and motor control features |
Compared with NXP S32K344 and Renesas RH850/U2A, CYT2B64BADQ0AZSGST uniquely balances ASIL-B safety, HSM-grade security, LIN PHY integration, and synchronized triple ADC-making it optimal for cost-constrained, feature-rich body electronics rather than domain controllers or powertrain systems.

FAQ
What is the maximum operating temperature range for CYT2B64BADQ0AZSGST?
The CYT2B64BADQ0AZSGST is rated for –40°C to +125°C (E-grade), validated per AEC-Q100 Grade 0 qualification. This extended temperature range supports under-hood and door module deployments where ambient heat exceeds 105°C, and thermal derating is managed via internal temperature monitoring diodes and configurable low-power modes.
Does CYT2B64BADQ0AZSGST support Over-The-Air (FOTA) firmware updates?
Yes-CYT2B64BADQ0AZSGST supports secure FOTA through its dual-bank flash architecture (576 KB code-flash) and Read-While-Write capability. Firmware updates execute from one bank while writing to the other, with CRC32 validation and digital signature verification enforced by the HSM crypto engine before activation.
How many CAN FD channels does CYT2B64BADQ0AZSGST support, and what is their data rate?
CYT2B64BADQ0AZSGST supports three CAN FD channels (CAN0, CAN1, CAN2), each compliant with ISO 11898-1:2015 and capable of up to 8 Mbps data rate in the FD phase. Physical layer performance depends on external transceiver selection and bus topology, but the controller meets ISO 16845:2015 conformance testing requirements.
Is the crypto engine enabled by default, or does it require firmware configuration?
The crypto engine-including AES, SHA, TRNG, and ECC/RSA acceleration-is hardware-present but requires explicit firmware initialization and key provisioning. Enhanced Secure Hardware Extension (eSHE) must be enabled via third-party firmware; HSM functionality is only active in parts ordered with HSM option codes (e.g., "HSM" suffix in MPN), not in eSHE-only variants.
