Product details
Overview
CYT2B97CACQ0AZEGST from Infineon is a dual-core automotive microcontroller featuring a 160-MHz Arm® Cortex®-M4F CPU and a 100-MHz Arm® Cortex®-M0+ CPU, integrated CAN FD (up to 8 channels), LIN (up to 12 channels), and CXPI (up to 4 channels), with 2112-KB code-flash, 256-KB SRAM, and hardware crypto engine supporting AES-128/192/256, SHA-256/512, and ECC for secure boot in body control units.
For engineers reviewing the CYT2B97CACQ0AZEGST datasheet, CYT2B97CACQ0AZEGST pinout, CYT2B97CACQ0AZEGST application, or CYT2B97CACQ0AZEGST equivalent, this part delivers ASIL-B functional safety, RWW flash for FOTA updates, SECDED ECC on SRAM/flash, low-power DeepSleep/Hibernate modes, and runtime-reconfigurable SCB blocks for I²C/SPI/UART - critical for automotive ECU design requiring real-time determinism and security.
Technical Context
The device implements a tightly coupled dual-CPU architecture where the M4F handles primary application tasks with FPU and MPU, while the M0+ offloads peripheral management, security services (eSHE/HSM), and inter-processor communication via hardware mailbox. Memory subsystem includes dual-bank flash supporting atomic firmware updates and configurable SRAM retention granularity.
Peripherals are routed through a hierarchical bus matrix with PPU-enforced access control; clocking uses multiple sources (IMO, ECO, WCO, PLL/FLL) with CSV supervision; analog subsystem integrates three SAR ADCs (12-bit, 1 Msps) with synchronized sampling and smart I/O blocks enabling Boolean logic on GPIO signals without CPU intervention.

Applications
| Body Control Module (BCM) | Door Module Control |
|---|---|
Use Scenario: Centralized vehicle body functions including lighting, window lift, mirror adjustment, and door lock actuation. IC Role / Device Role / Timing Role: Primary MCU managing LIN/CAN FD communication with slave nodes, executing real-time PWM for motor drivers, and handling secure keyless entry authentication.

IC Role / Device Role / Timing Role: Local controller interfacing with LIN slaves (e.g., window switch, mirror motor) and CAN FD gateway; performs position-sensing via ADC and PWM motor control. Use Value: Synchronized ADC sampling captures motor current and voltage simultaneously for stall detection; Smart I/O reduces CPU load for debounce and edge detection on mechanical switches. |
| Roof Module (Sunroof/Climate) | Seat Control Unit |
Use Scenario: Sunroof position control, tilt/sliding actuation, and ambient light/temperature sensing for automatic climate response. IC Role / Device Role / Timing Role: Real-time TCPWM control of DC motors with dead-time insertion, SAR ADC acquisition of thermistor and photodiode inputs, and CAN FD status reporting. Use Value: Hardware CRC32 and SECDED ECC protect flash and SRAM against bit flips in high-EMI roof environments; DeepSleep mode extends battery life during vehicle off-state. | Use Scenario: Motorized seat positioning (fore/aft, recline, lumbar), heating element control, and occupancy detection via pressure sensors. IC Role / Device Role / Timing Role: Multi-axis motor control using 12 dedicated 16-bit motor timers, simultaneous ADC reads from 6+ pressure sensors, and LIN communication to central BCM. Use Value: Three independent SAR ADCs scan all seat sensors concurrently; crypto engine signs seat calibration data to prevent tampering during service programming. |
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 eSHE/HSM co-processor | Targets higher-performance gateway/routing applications; less optimized for peripheral offload and secure boot latency | Select when higher single-thread compute throughput is required over dual-core task isolation and ultra-low boot time |
| Renesas RH850/U2A | 32-bit RXv3 core (not Arm); 400-MHz peak; supports CAN FD and LIN but no CXPI; no hardware FPU or crypto acceleration for ECC/SHA-512 | Focused on powertrain and chassis control; limited analog integration (single 10-bit ADC) and no Smart I/O capability | Select for legacy RX ecosystem migration or where ISO 26262 ASIL-D certification path is mandatory |
Compared with NXP S32K344 and Renesas RH850/U2A, CYT2B97CACQ0AZEGST uniquely combines Arm dual-core determinism, CXPI support for next-gen body networks, synchronized triple ADCs for motor sensing, and hardware-accelerated ECC/SHA-512 - making it optimal for cost-sensitive, ASIL-B-compliant body domain controllers requiring rapid secure boot and flexible peripheral routing.

FAQ
What is the maximum operating frequency of the Cortex-M4F core in CYT2B97CACQ0AZEGST?
The Arm® Cortex®-M4F core operates at a maximum frequency of 160 MHz, confirmed in the official Infineon datasheet (Rev. *I, p.5). This speed is achievable under specified voltage (1.1 V ±5%) and temperature (-40°C to +105°C) conditions, and enables real-time execution of motor control algorithms and cryptographic operations without throttling.
Does CYT2B97CACQ0AZEGST support Over-The-Air (OTA) firmware updates?
Yes - it supports secure OTA updates via dual-bank flash architecture with Read-While-Write capability, allowing one bank to execute while the other is reprogrammed. The hardware crypto engine verifies digital signatures (RSA/ECC) before committing updates, ensuring authenticity and integrity as defined in Infineon's TRAVEO™ T2G security documentation.
How many CAN FD channels does CYT2B97CACQ0AZEGST support, and what is the maximum data rate?
CYT2B97CACQ0AZEGST supports up to eight CAN FD channels, each compliant with ISO 11898-1:2015 and capable of data rates up to 8 Mbps. Physical layer limitations (transceiver and topology) apply, and the device includes ISO 16845:2015 conformance testing support for interoperability validation.
Is the CYT2B97CACQ0AZEGST pin-compatible with other TRAVEO™ T2G variants?
No - CYT2B97CACQ0AZEGST uses the 176-LQFP package (24×24 mm), while other CYT2B9 variants include 64-, 80-, 100-, and 144-LQFP options. Pin mapping differs across packages; the 176-LQFP variant provides full peripheral access (e.g., all 8 CAN FD channels, 152 GPIOs), and migration requires PCB redesign and signal validation per Infineon's pin assignment tables.
