Product details
Overview
CYT2B98BACQ0AZSGST 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 CYT2B98BACQ0AZSGST datasheet, CYT2B98BACQ0AZSGST pinout, CYT2B98BACQ0AZSGST application, or CYT2B98BACQ0AZSGST equivalent, this part delivers deterministic real-time control, hardware-enforced security isolation between cores, and fine-grained power management across Hibernate, DeepSleep, and Low-power Sleep modes - critical for automotive ECU firmware update, sensor fusion, and secure gateway functions.
Technical Context
The device implements hardware inter-processor communication (IPC) between M4F and M0+ subsystems, enabling secure peripheral offload and asymmetric task partitioning. Its three DMA controllers - P-DMA0 (92 channels), P-DMA1 (44 channels), and M-DMA0 (4 channels) - support concurrent memory-to-peripheral, peripheral-to-peripheral, and memory-to-memory transfers without CPU intervention.
Functional safety is enforced via MPU on both CPUs, Shared Memory Protection Unit (SMPU), Peripheral Protection Unit (PPU), SECDED ECC on flash and SRAM, and dual-threshold Brown-out Detection (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.

Applications
| Body Control Module (BCM) | Automotive Gateway |
|---|---|
|
Use Scenario: Centralized control of lighting, door locks, window lifts, and HVAC in modern vehicle platforms. IC Role / Device Role / Timing Role: Primary MCU executing real-time PWM dimming, LIN slave coordination, and CAN FD message routing between domains. Use Value: Dual-core separation allows safety-critical lock/unlock logic (M0+) to run independently of non-critical ambient lighting control (M4F), meeting ASIL-B requirements. |
Use Scenario: Aggregation and translation of messages between CAN FD backbone, LIN subnets (e.g., seat/mirror), and CXPI sensors (e.g., rain/light sensors). IC Role / Device Role / Timing Role: Protocol bridge with hardware-accelerated frame filtering, store-and-forward buffering, and secure message signing. Use Value: Eight CAN FD channels and twelve LIN ports enable direct termination without external transceivers or protocol converters, reducing BOM count and latency. |
| Electric Power Steering (EPS) Support | Secure OTA Update Controller |
|
Use Scenario: Sensor fusion and motor torque command generation in EPS ECUs where timing determinism and fault containment are critical. IC Role / Device Role / Timing Role: Real-time controller with synchronized 12-bit ADC sampling across three SARs and precise PWM generation with dead-time compensation. Use Value: Simultaneous sampling of motor phase currents and position sensors eliminates skew; TCPWM blocks deliver <100-ns dead-time resolution for IGBT/FET gate drive. |
Use Scenario: Secure download, authentication, and installation of signed firmware patches in production vehicles without service bay tools. IC Role / Device Role / Timing Role: Root-of-trust execution environment managing cryptographic verification, flash bank switching, and rollback validation. Use Value: Hardware HSM accelerates ECDSA signature verification in <5 ms; dual-bank flash enables verified update activation within one reset cycle. |
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 240-MHz Arm® Cortex®-M7 core; no companion M0+; includes ASIL-D capable lockstep mode | Better suited for high-integrity powertrain control; lacks native CXPI and has fewer LIN channels (6 vs. 12) | Select when ASIL-D certification is mandatory and LIN/CXPI count is secondary |
| Renesas RH850/U2A | 32-bit RXv3 core (not Arm); 400-MHz peak; integrated CAN FD, LIN, and SENT; no hardware crypto accelerator | Strong legacy automotive toolchain support; requires external crypto IC for secure boot or TLS | Select for brownfield designs already using RH850 ecosystem and where external security co-processor is acceptable |
Compared with NXP S32K344 and Renesas RH850/U2A, CYT2B98BACQ0AZSGST uniquely balances ASIL-B safety, native CXPI integration, dual-core security partitioning, and hardware-accelerated crypto - making it optimal for next-gen body electronics where protocol diversity and firmware trust are equally critical.

FAQ
What is the operating temperature range for CYT2B98BACQ0AZSGST?
This device is qualified for automotive use with an operating junction temperature range of –40°C to +125°C, and is specified for continuous operation under these conditions per AEC-Q100 Grade 2 requirements. All electrical parameters in the datasheet are guaranteed across this full range, including flash endurance and SRAM retention.
Does CYT2B98BACQ0AZSGST support hardware-based secure boot?
Yes - it implements hardware-accelerated secure boot using ECDSA/ECC signature verification against a public key stored in eFuse. The boot ROM validates firmware images before loading into RAM, and enforces chain-of-trust execution only if signatures match. Fast secure boot completes within 10 ms.
How many CAN FD channels are physically implemented in this specific variant?
CYT2B98BACQ0AZSGST implements all eight CAN FD channels (CAN0–CAN7) as defined in the CYT2B9 family datasheet. Each channel supports ISO 11898-1:2015 compliance, up to 8 Mbps data rate, and hardware message filtering with up to 128 acceptance masks per channel.
Is external flash required for firmware storage?
No - the device integrates 2112-KB on-chip code-flash with Read-While-Write capability and dual-bank architecture, eliminating need for external flash in most automotive applications. Work-flash (128 KB) provides additional non-volatile storage for calibration data and runtime parameters.
