Product details
Overview
CYT2B98BACQ0AZEGST 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); deployed in body control modules requiring ASIL-B functional safety compliance.
For engineers reviewing the CYT2B98BACQ0AZEGST datasheet, CYT2B98BACQ0AZEGST pinout, CYT2B98BACQ0AZEGST application, or CYT2B98BACQ0AZEGST equivalent, this part supports secure boot via eSHE/HSM, hardware-accelerated crypto (AES-128/192/256, SHA-256/512, ECC, RSA), synchronized SAR ADC sampling for motor sensing, and fine-grained low-power modes including Hibernate with dual-pin wakeup.
Technical Context
The CYT2B98BACQ0AZEGST implements a tightly coupled dual-CPU architecture: the M4F handles real-time application processing with FPU and MPU, while the M0+ manages peripheral offload, security services, and inter-processor communication via dedicated hardware mailbox. Its clock system integrates IMO, ILO, ECO, WCO, PLL, and FLL for flexible timing control across power states.
Peripheral protection is enforced by PPU, SMPU, and SECDED ECC on all safety-critical memories; analog subsystems include three 12-bit SAR ADCs (67 total external channels, 1 Msps max rate) with sequencer-driven autonomous scanning and synchronized sampling capability for motor control feedback loops.

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 |
|---|---|---|---|
| S32K344 | Single-core Arm® Cortex®-M7 (320 MHz), no M0+ co-processor; includes HSE security module but lacks hardware mailbox IPC | Targeted at higher-performance gateway/radar applications; less suitable for strict ASIL-B decomposition requiring physical core isolation | Prefer when raw M7 compute throughput >160 MHz is required and security tasks can be software-managed |
| TC397 | Tri-core (2× TriCore + 1× Cortex®-M7), 300 MHz, AURIX™ safety architecture with lockstep cores; no CAN FD native support (requires external PHY) | Designed for chassis/safety-critical domains (ASIL-D); larger die size and higher cost than CYT2B9 for body electronics | Prefer when ASIL-D certification or lockstep redundancy is mandatory, not for cost-sensitive BCM designs |
Compared with S32K344 and TC397, CYT2B98BACQ0AZEGST delivers optimal balance of ASIL-B compliance, dual-core hardware isolation, CAN FD integration, and power efficiency for body electronics-without over-specifying for non-safety-critical domains.

FAQ
Does CYT2B98BACQ0AZEGST support CAN FD without external transceivers?
No. CYT2B98BACQ0AZEGST provides CAN FD protocol logic and physical layer signaling (TX/RX differential pairs) but requires external CAN FD transceivers (e.g., TJA1044, IFX1050) to drive the bus. The MCU handles bit timing, arbitration, and frame formatting internally.
What is the maximum operating temperature range for this device?
CYT2B98BACQ0AZEGST is qualified for automotive AEC-Q100 Grade 2 operation, supporting ambient temperatures from −40 °C to +105 °C. Junction temperature must remain ≤125 °C under continuous operation, verified per thermal derating curves in Section 27.2 of the datasheet.
How is secure boot implemented in CYT2B98BACQ0AZEGST?
Secure boot uses hardware-enforced digital signature verification of the boot image using ECDSA with P-256 curve. The public key is fused into eFuses; only images signed with the corresponding private key execute. Boot ROM validates signatures before loading code into SRAM or flash, preventing unauthorized firmware execution.
Can the 176-LQFP package be used with standard reflow profiles?
Yes. CYT2B98BACQ0AZEGST's 176-LQFP package complies with JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) and supports standard lead-free reflow profiles (peak 260 °C, 20–40 sec above 217 °C). Pre-bake at 125 °C for 8 hours is required if exposed >168 hours at >30 °C/60% RH.
