Product details
Overview
CYT2B98CACQ0AZSGST 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 CYT2B98CACQ0AZSGST datasheet, CYT2B98CACQ0AZSGST pinout, CYT2B98CACQ0AZSGST application, or CYT2B98CACQ0AZSGST 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 design and OTA firmware updates.
Technical Context
The CYT2B98CACQ0AZSGST implements a tightly coupled dual-CPU architecture: the M4F handles primary application tasks with FPU and single-cycle multiply, 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 with configurable dividers and failover paths.
Peripheral subsystems include three DMA controllers (P-DMA0 with 92 channels, P-DMA1 with 44, M-DMA0 with 4), seven TCPWM blocks supporting motor control PWM_DT and quadrature decoding, and five Smart I/O units enabling Boolean logic on GPIO_STD signals-enabling autonomous signal conditioning without CPU intervention.

Applications
| Body Control Module (BCM) | Door Module Controller |
|---|---|
|
Use Scenario: Centralized management of lighting, window lift, mirror fold, and seat position in modern vehicle door assemblies. IC Role / Device Role / Timing Role: Primary MCU executing LIN slave protocol stacks, PWM-driven motor control, and CAN FD gateway routing between body domain networks. Use Value: Integrated LIN (12 channels) and CAN FD (8 channels) eliminate external protocol translators; Smart I/O reduces need for discrete logic ICs in window anti-pinch sensing. |
Use Scenario: Real-time coordination of power window, lock actuator, and side mirror controls within a single door ECU. IC Role / Device Role / Timing Role: Dual-core runtime partitioning: M4F runs motor control loops at 10 kHz, M0+ handles LIN communication and fault logging independently. Use Value: On-chip 256-KB SRAM with retention control enables fast resume from Sleep mode (<10 µs), critical for responsive window operation after ignition-off. |
| Roof Module Controller | Smart Junction Box |
|
Use Scenario: Sunroof, panoramic roof, and ambient lighting control with thermal monitoring and overcurrent protection. IC Role / Device Role / Timing Role: SAR ADC (67-channel aggregate) acquires temperature, voltage, and current sensor data; TCPWM generates synchronized PWM for RGB LED dimming. Use Value: Three independent SAR ADCs with synchronized sampling enable simultaneous acquisition of motor current, thermistor, and supply rail-reducing BOM cost vs. external ADCs. |
Use Scenario: Power distribution and load switching for interior lighting, HVAC fans, and infotainment peripherals in centralized junction boxes. IC Role / Device Role / Timing Role: HSM-enforced secure boot validates signed configuration tables; PPU enforces access control to GPIO-controlled MOSFET drivers. Use Value: Hardware Security Module (HSM) and Peripheral Protection Unit (PPU) provide root-of-trust for remote reconfiguration-meeting OEM cybersecurity requirements for OTA updates. |
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 |
|---|---|---|---|
| S32K344UAT0VLQY | Single-core Arm® Cortex®-M7 @ 320 MHz; no M0+ co-processor; includes Ethernet MAC and ASIL-D support. | Better suited for gateway applications requiring Ethernet backbone integration and higher ASIL level; lacks native CXPI and Smart I/O. | Select when Ethernet connectivity or ASIL-D certification is mandatory; avoid if LIN/CXPI count or hardware Boolean I/O logic is required. |
| TC375LP-32F200N AC | Tri-core (2× TriCore™ + 1× GTM); 200-MHz main core; includes GTM timer engine but no integrated crypto HSM. | Stronger deterministic timing for motor control via GTM; requires external crypto IC for secure boot and OTA signing. | Prefer for high-precision motor control where GTM's event-triggered PWM outweighs need for on-die HSM; verify external crypto sourcing. |
Compared with S32K344UAT0VLQY and TC375LP-32F200N AC, CYT2B98CACQ0AZSGST uniquely balances dual-core autonomy, CXPI/LIN density, Smart I/O logic, and certified HSM-all in a 176-LQFP package-making it optimal for cost-sensitive, feature-rich body domain ECUs without Ethernet or ASIL-D requirements.

FAQ
Does CYT2B98CACQ0AZSGST support CAN FD ISO 11898-1:2015 compliance?
Yes. The device implements eight CAN FD channels fully compliant with ISO 11898-1:2015, including bit-rate switching, flexible data length (up to 64 bytes), and CRC coverage extension. It also holds ISO 16845:2015 conformance certification for physical layer interoperability testing.
What is the maximum operating temperature range for this part?
CYT2B98CACQ0AZSGST is qualified per AEC-Q100 Grade 2, supporting continuous operation from −40 °C to +105 °C ambient temperature. Junction temperature limits are defined by thermal resistance (θJA = 26.5 °C/W for 176-LQFP) and power dissipation under worst-case CPU/peripheral load.
Is the hardware crypto engine enabled in this specific MPN?
Yes. CYT2B98CACQ0AZSGST includes the full HSM crypto engine: AES-128/192/256, SHA-256/512, ECC, RSA, TRNG, and GCM. This is confirmed by its ordering code suffix "ZSGST", which denotes HSM-enabled silicon per Infineon's CYT2B9 ordering nomenclature (Rev. *I, p.142).
Can the M0+ core execute LIN protocol stack independently of the M4F core?
Yes. The M0+ runs dedicated firmware handling LIN frame generation, checksum calculation, and schedule table management-communicating status and payload via hardware mailbox. This frees the M4F for application logic and enables deterministic LIN timing even under heavy M4F load.
