Product details
Overview
CYT2B98BACQ0AZSGS 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 CYT2B98BACQ0AZSGS datasheet, CYT2B98BACQ0AZSGS pinout, CYT2B98BACQ0AZSGS application, or CYT2B98BACQ0AZSGS equivalent, this part delivers deterministic real-time control, hardware-enforced memory protection (MPU/SMPU), SECDED ECC on flash/SRAM, and low-power DeepSleep/Hibernate modes with multi-pin wakeup-critical for automotive ECU firmware update, sensor fusion, and secure gateway design.
Technical Context
The CYT2B98BACQ0AZSGS implements a tightly coupled dual-CPU architecture: the M4F handles primary application tasks with FPU and MPU, while the M0+ offloads peripheral management, security services (eSHE/HSM), and secure boot verification. Inter-processor communication occurs via dedicated hardware mailboxes 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. Clocking is managed by IMO, ILO, ECO, WCO, PLL, and FLL sources, with configurable BOD thresholds (2.7 V / 3.0 V on VDDD/VDDA, 1.1 V on VCCD).

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); no M0+ companion core; includes HSE security module but lacks native CXPI support | Stronger compute throughput for motor control algorithms; limited to CAN FD + LIN only-no CXPI for legacy body networks | Select when higher M7 performance is required and CXPI is not needed; verify LIN/CAN FD channel count matches system topology |
| Renesas RH850/U2A | 32-bit RH850 core (240 MHz); proprietary ISA; integrated CAN FD (6 ch), LIN (10 ch), but no hardware crypto accelerator or RWW flash | Proven in Japanese OEM BCMs; requires external secure element for OTA signature verification and lacks FOTA-ready flash architecture | Prefer where existing RH850 toolchain and ecosystem integration outweigh need for integrated HSM and dual-bank flash |
Compared with S32K344 and RH850/U2A, CYT2B98BACQ0AZSGS uniquely combines dual-core deterministic partitioning, native CXPI support, RWW flash for seamless FOTA, and full HSM-based secure boot-making it optimal for next-gen zonal gateways requiring protocol diversity and embedded trust anchors.
