Infineon Technologies CYT2B97CACQ0AZSGS

Overview

CYT2B97CACQ0AZSGS 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 including AES-128/192/256, SHA-256/512, and ECC.

For engineers reviewing the CYT2B97CACQ0AZSGS datasheet, CYT2B97CACQ0AZSGS pinout, CYT2B97CACQ0AZSGS application, or CYT2B97CACQ0AZSGS equivalent, this part delivers verified dual-CPU partitioning for real-time control + security offload, certified ISO 11898-1:2015 CAN FD compliance, and production-ready FOTA support via dual-bank flash architecture.

Technical Context

The CYT2B97CACQ0AZSGS implements hardware-enforced inter-processor communication between its M4F and M0+ cores, enabling deterministic peripheral management and secure boot execution in separate trust domains. Its three DMA controllers-P-DMA0 (92 channels), P-DMA1 (44 channels), and M-DMA0 (4 channels)-support concurrent high-bandwidth data movement across peripherals and memory without CPU intervention.

Functional safety is implemented via MPU, SMPU, PPU, SECDED ECC on all safety-critical memories, and dual-threshold BOD (2.7 V / 3.0 V on VDDD/VDDA; 1.1 V on VCCD). Clock supervision includes CSV, FLL, PLL, IMO, ILO, ECO, and WCO sources with failover capability.

Key Specifications
