Infineon Technologies CYT3BB7CEBQ0AEEGST

Overview

CYT3BB7CEBQ0AEEGST from Infineon Technologies is a TRAVEO™ T2G 32-bit automotive microcontroller featuring dual Arm® Cortex®-M7 CPUs (250 MHz), one Arm® Cortex®-M0+ CPU (100 MHz), 4160 KB code-flash, 768 KB SRAM, and integrated CAN FD (up to 8 Mbps), Ethernet MAC (10/100 Mbps), and LIN (16 channels). It targets high-end body-control units requiring ASIL-B functional safety, secure boot, and hardware cryptography acceleration.

For engineers reviewing the CYT3BB7CEBQ0AEEGST datasheet, CYT3BB7CEBQ0AEEGST pinout, CYT3BB7CEBQ0AEEGST application, or CYT3BB7CEBQ0AEEGST equivalent, key selection criteria include dual-core deterministic real-time execution, ISO 11898-1:2015–compliant CAN FD timing, IEEE-802.3bw Ethernet MAC with RMII/MII support, eSHE/HSM security compliance, and 220 GPIO with programmable retention in DeepSleep mode.

Technical Context

The device implements a heterogeneous dual-CPU subsystem: two lockstep-capable Cortex-M7 cores for primary control and safety-critical tasks, plus a dedicated Cortex-M0+ core handling peripheral offload and secure runtime services. Memory subsystem includes SECDED ECC on all safety-critical memories (flash, SRAM, TCM) and Read-While-Write capability across both code- and work-flash banks.

Clock architecture integrates IMO, ILO, ECO, WCO, PLL, and FLL with hardware clock supervision (CSV); power management supports five low-power modes (Active, Sleep, Low-power Sleep, DeepSleep, Hibernate) with configurable BOD thresholds (2.7 V / 3.0 V on VDDD/VDDA, 1.1 V on VCCD) and multi-source wakeup (GPIO, RTC, MCWDT, EVTGEN).

FAQ

What is the maximum operating temperature range for CYT3BB7CEBQ0AEEGST?

The device is qualified per AEC-Q100 Grade 2, supporting continuous operation from −40 °C to +105 °C ambient temperature. Junction temperature limits are enforced by on-die thermal sensors and hardware-monitored LVD/BOD circuits, with automatic throttling initiated above 125 °C junction to prevent permanent damage.

Does CYT3BB7CEBQ0AEEGST support AUTOSAR Classic and Adaptive platforms?

Yes - the dual Cortex-M7 cores with MPU and SECDED ECC memory meet AUTOSAR Classic OS requirements for ASIL-B applications, while the Ethernet MAC with IEEE-1588 PTP and 768 KB SRAM supports AUTOSAR Adaptive execution environments. Infineon provides certified MCAL drivers and Adaptive Platform middleware integration packages.

How is secure boot implemented on this MCU?

Secure boot uses hardware-verified digital signature checking of the first-stage bootloader stored in immutable ROM. The public key is fused into OTP eFuse; only images signed with the corresponding private key execute. Boot flow enforces chain-of-trust through HSM-validated decryption of subsequent firmware stages before loading into TCM or SRAM.

Can the CAN FD interfaces operate simultaneously at different bit rates?

Yes - each of the eight CAN FD channels supports independent configuration of nominal and data phase bit rates (up to 8 Mbps in data phase). Bit timing registers are per-channel and fully programmable, allowing mixed-rate operation across buses (e.g., 500 kbps nominal / 2 Mbps data on CAN0, 1 Mbps nominal / 5 Mbps data on CAN1) without cross-channel interference.
