Product details
Overview
CYT2B64CADQ0AZEGS 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 576 KB code-flash, 64 KB SRAM, CAN FD (up to 8 Mbps), LIN, 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 CYT2B64CADQ0AZEGS datasheet, CYT2B64CADQ0AZEGS pinout, CYT2B64CADQ0AZEGS application, or CYT2B64CADQ0AZEGS equivalent, key selection criteria include dual-CPU real-time partitioning, CAN FD timing compliance (ISO 11898-1:2015), eSHE/HSM security certification, RWW flash update capability, and 100-LQFP package compatibility with automotive thermal requirements (125 °C E-grade).
Technical Context
The device implements a tightly coupled dual-CPU subsystem where the M4F handles primary application tasks and the M0+ manages time-critical peripherals and secure boot authentication. Inter-processor communication occurs via dedicated hardware mailboxes and shared memory protected by SMPU.
Its safety architecture includes SECDED ECC on all SRAM and flash, MPU/PPU/SMPU enforcement, dual-threshold BOD (2.7 V / 3.0 V), and MCWDT with independent clock domains-enabling deterministic fault containment per ISO 26262 ASIL-B requirements.

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 |
|---|---|---|---|
| S32K344WAT0MLHT | NXP S32K3 series; single 220-MHz Arm Cortex-M7 core with lock-step M7 for ASIL-D; no integrated M0+ companion core | Targeted at higher-ASIL domains (e.g., chassis control); lacks native dual-core task partitioning for mixed-criticality workloads | Select when ASIL-D compliance or higher compute throughput outweighs need for hardware-isolated peripheral management. |
| TC375LPDCAKXUMA1 | Infineon AURIX™ TC3xx; tri-core (3× TriCore), 300 MHz; ASIL-D capable; no native CAN FD crypto acceleration | Used in powertrain and ADAS; requires external HSM for full TLS/secure boot; larger footprint and cost | Select when multi-core deterministic scheduling and lock-step redundancy are mandatory, not just dual-core separation. |
Compared with S32K344 and TC375, CYT2B64CADQ0AZEGS uniquely balances ASIL-B compliance, hardware-enforced dual-core isolation, integrated CAN FD crypto, and compact 100-LQFP packaging-making it optimal for cost-sensitive, thermally constrained body electronics where mixed-criticality partitioning is essential.
