Product details
Overview
CYT2B64CADQ0AZEGST from Infineon Technologies (formerly Cypress) is a dual-core automotive-grade microcontroller featuring an 80-MHz Arm® Cortex®-M4F CPU with FPU and an 80-MHz Arm® Cortex®-M0+ CPU for peripheral/security offload. It integrates CAN FD (up to 8 Mbps), LIN, 3× 12-bit SAR ADCs (1 Msps), 576 KB code-flash, and hardware crypto acceleration (AES-128/192/256, SHA-256/512, ECC, TRNG). Designed for body control units, it supports ASIL-B functional safety and operates from 2.7 V to 5.5 V.
For engineers reviewing the CYT2B64CADQ0AZEGST datasheet, CYT2B64CADQ0AZEGST pinout, CYT2B64CADQ0AZEGST application, or CYT2B64CADQ0AZEGST equivalent, key selection criteria include dual-CPU real-time partitioning, CAN FD channel count (3 total), flash RWW capability, SRAM retention granularity, and eSHE/HSM security compliance for automotive firmware updates and secure boot.
Technical Context
The CYT2B64CADQ0AZEGST implements a tightly coupled dual-CPU subsystem where the M4F handles primary application tasks and the M0+ manages time-critical peripherals and security services via hardware inter-processor communication. Its memory subsystem includes 576 KB code-flash (dual-bank for FOTA), 64 KB work-flash, and 64 KB SRAM with configurable retention-enabling robust over-the-air update workflows without runtime interruption.
Functional safety is enforced through MPU, SMPU, PPU, SECDED ECC on SRAM/flash, dual watchdogs (WDT/MCWDT), and voltage monitors (LVD/BOD/OVD). The crypto engine delivers certified AES-GCM, SHA-2/3, RSA/ECC, and TRNG-meeting eSHE and HSM requirements for secure boot, authentication, and encrypted communication in ASIL-B systems.

FAQ
What is the maximum CAN FD data rate supported by CYT2B64CADQ0AZEGST?
CYT2B64CADQ0AZEGST supports up to 8 Mbps per CAN FD channel, compliant with ISO 11898-1:2015 and Bosch CAN FD Specification V1.0. This rate is achievable under optimal physical layer conditions (e.g., short stub lengths, matched termination, low-noise transceivers) and requires proper configuration of bit timing registers and transceiver selection.
Does CYT2B64CADQ0AZEGST support true hardware-based secure boot?
Yes-it implements fast secure boot using digital signature verification (ECDSA or RSA) executed entirely within the hardware crypto engine. Boot ROM validates the signature of the first-stage bootloader before execution, with keys stored in write-protected eFuses or secure flash regions. No software intervention is required during the boot chain.
How many GPIOs support wakeup from DeepSleep mode?
Up to 78 GPIO pins can generate interrupts to wake the device from Sleep modes. For DeepSleep mode, wakeup is enabled via dedicated peripherals: Event Generator (EVTGEN), SCB, RTC alarms, or Watchdog Timer-not individual GPIOs. EVTGEN timers provide cyclic wakeup capability with sub-millisecond jitter.
Is the 64 KB SRAM fully retainable during Hibernate mode?
No-SRAM retention in Hibernate mode is configurable in 8-KB granules. By default, only 8 KB is retained; users may select additional 8-KB blocks (up to full 64 KB) via the PMIC register, but increased retention raises leakage current. Retention granularity is controlled independently per 8-KB segment to balance power and state preservation.
