Product details
Overview
CYT2B98CACQ0AZEGST 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 (AES-128/192/256, SHA-256/512, ECC, TRNG).
For engineers reviewing the CYT2B98CACQ0AZEGST datasheet, CYT2B98CACQ0AZEGST pinout, CYT2B98CACQ0AZEGST application, or CYT2B98CACQ0AZEGST equivalent, this part delivers verified dual-CPU partitioning, hardware inter-processor communication, SECDED ECC on flash/SRAM, configurable low-power modes (Hibernate/DeepSleep), and ISO 11898-1:2015–compliant CAN FD up to 8 Mbps.
Technical Context
The CYT2B98CACQ0AZEGST implements a tightly coupled dual-CPU architecture where the M4F handles primary application execution and motor control timing, while the M0+ manages peripheral offload, security services (eSHE/HSM), and real-time LIN/CXPI protocol stacks. Hardware mailbox and shared memory enable deterministic IPC without software arbitration.
Its safety architecture includes MPU on both cores, SMPU for shared resources, PPU for peripheral access control, and SECDED ECC on all safety-critical memories. Clock supervision (CSV), multi-counter watchdog (MCWDT), and dual-threshold BOD (2.7 V / 3.0 V on VDDD/VDDA) support ASIL-B compliance per ISO 26262.

| Motor Control Timing | 75× 16-bit and 8× 32-bit TCPWM blocks support PWM_DT, quadrature decoding, and synchronized ADC triggering for BLDC/PMSM commutation |
Applications
| Body Control Module (BCM) | Roof Module Controller |
|---|---|
|
Use Scenario: Centralized management of door locks, window lifts, lighting, and seat position memory in premium vehicles. IC Role / Device Role / Timing Role: Primary MCU executing CAN FD gateway logic, LIN slave coordination, and secure firmware updates. Use Value: Dual-core isolation ensures LIN timeout compliance while M4F processes CAN FD diagnostics-no task starvation under peak bus load. |
Use Scenario: Integrated control of sunroof, panoramic roof panels, ambient lighting, and rain sensors in modular roof assemblies. IC Role / Device Role / Timing Role: Real-time coordinator between CXPI-connected sensors and CAN FD–connected body domain controller. Use Value: CXPI's 20-kbps daisy-chain reduces wiring harness weight by 30% vs. discrete LIN; synchronized ADC sampling captures simultaneous light/rain events. |

IC Role / Device Role / Timing Role: High-reliability safety MCU managing power sequencing, overcurrent protection, and ASIL-B fault reporting. Use Value: SECDED ECC on flash/SRAM and dual-threshold BOD ensure uninterrupted operation during battery voltage dips (e.g., cranking at 6.5 V). |
Use Scenario: Position memory, heating/ventilation control, and posture adjustment for multi-motor electric seats. IC Role / Device Role / Timing Role: Motor timing controller with synchronized 3-ADC capture for current/voltage/temperature feedback across 3 motors. Use Value: 75× TCPWM blocks and synchronized ADC scanning enable precise field-oriented control (FOC) without external timing ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K344 | Single 240-MHz Arm® Cortex®-M7 core; no companion M0+; includes HSE security module but lacks native CXPI | Targets higher-performance chassis/safety domains; requires external LIN/CXPI transceivers | Prefer when M7 performance > dual-core partitioning; avoid if CXPI integration or ASIL-B peripheral offload is required |
| Renesas RH850/U2A | 300-MHz RH850 core; proprietary ISA; 1.25 MB flash; no integrated crypto accelerator (AES/SHA/ECC) | Used in powertrain and ADAS; relies on external HSM for secure boot | Choose only if legacy RH850 toolchain compatibility is mandatory; not suitable for cost-sensitive body domain with crypto needs |
Compared with NXP S32K344 and Renesas RH850/U2A, CYT2B98CACQ0AZEGST uniquely combines dual-core deterministic partitioning, native CXPI, and on-die HSM-reducing BOM count and enabling ASIL-B body control without external security chips or protocol bridges.

FAQ
What is the maximum operating temperature range for CYT2B98CACQ0AZEGST?
CYT2B98CACQ0AZEGST is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. Junction temperature limits are enforced via on-die thermal sensor and configurable thermal shutdown thresholds in the System Configuration Block (SCB), ensuring reliability in under-hood and cabin-mounted automotive applications.
Does CYT2B98CACQ0AZEGST support OTA firmware updates without external memory?
Yes. Its 2112 KB code-flash supports dual-bank mode with Read-While-Write capability, enabling atomic firmware swaps directly from internal flash. The M0+ core handles secure signature verification and bank switching while the M4F continues real-time operation-no external SPI NOR or EEPROM required.
How many CAN FD channels are physically implemented in this specific variant?
CYT2B98CACQ0AZEGST implements all eight CAN FD channels (CAN0–CAN7) as defined in the CYT2B9 family datasheet. Each channel has dedicated TX/RX pins, independent message RAM, and full ISO 11898-1:2015 compliance-including flexible data-rate arbitration and payload phases up to 64 bytes.
Is hardware cryptographic acceleration available without additional licensing?
Yes. AES-128/192/256, SHA-256/512, ECC, RSA, and TRNG are implemented in dedicated on-die hardware (Crypto Engine v2) and enabled by default. No runtime license key or firmware activation is required-the features are silicon-gated and accessible via standard PSoC™ Creator or ModusToolbox™ APIs.
