Product details
Overview
CYT3BB5CEBQ0AEEGS from Infineon 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 compliance, secure boot, and hardware cryptography acceleration.
For engineers reviewing the CYT3BB5CEBQ0AEEGS datasheet, CYT3BB5CEBQ0AEEGS pinout, CYT3BB5CEBQ0AEEGS application, or CYT3BB5CEBQ0AEEGS equivalent, this page delivers verified technical context, validated pin-level functionality, real-world automotive use cases, and confirmed alternative parts with documented interface and safety-feature differences.
Technical Context
The device implements a heterogeneous dual-core architecture: two lockstep-capable Cortex-M7 cores for primary control and a dedicated Cortex-M0+ core for peripheral management and security services. Hardware inter-processor communication enables deterministic task partitioning between safety-critical and non-safety domains.
It integrates SECDED ECC on all safety-critical memories (SRAM, flash, TCM), SMPU/PPU/MPU for memory and peripheral protection, and supports ISO 11898-1:2015 CAN FD with up to eight concurrent channels - each capable of 8 Mbps data rate under compliant PHY topology.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K344 | Single Cortex-M7 @ 320 MHz; no integrated Ethernet MAC; uses external PHY for 100BASE-T1 | Lacks native Ethernet AVB/PTP support; relies on external PHY and switch for time-sensitive networking | Select when CAN FD + LIN + safety is primary requirement and Ethernet is not needed at MAC layer |
| Renesas RH850/U2A | Tri-core (RH850-G3M + dual lockstep); no hardware crypto accelerator; supports CAN FD but limited to 5 Mbps | Focused on powertrain with mature ASIL-D toolchain; lacks HSM and secure boot acceleration | Select for ASIL-D powertrain applications where cryptographic offload is handled externally or omitted |
Compared with NXP S32K344 and Renesas RH850/U2A, CYT3BB5CEBQ0AEEGS uniquely combines dual M7 cores, integrated 10/100 Ethernet MAC with PTP, and hardware-accelerated HSM - enabling consolidated gateway + security + timing functions in a single ASIL-B-certified package.

FAQ
What is the maximum CAN FD data rate supported by CYT3BB5CEBQ0AEEGS?
The device supports CAN FD up to 8 Mbps per channel, compliant with ISO 11898-1:2015 and Bosch CAN FD v1.0 specifications. Actual achievable rate depends on physical layer topology, transceiver capability, and bus length - with 5 Mbps typical for 10-m harnesses and 2 Mbps for 20-m configurations using standard automotive cabling.
Does CYT3BB5CEBQ0AEEGS include hardware support for IEEE-1588 Precision Time Protocol?
Yes - the integrated Ethernet MAC supports IEEE-1588 PTP timestamping at the MAC layer with hardware-assisted correction for ingress/egress delays. It provides sub-microsecond synchronization accuracy when paired with a compliant PHY and calibrated oscillator, enabling time-sensitive applications like AVB audio bridging and distributed control loops.
How is functional safety implemented for memory subsystems in this MCU?
SECDED (Single Error Correction, Double Error Detection) ECC is applied to all safety-critical memories: SRAM, code-flash, work-flash, and TCM. Each memory block includes dedicated parity generation and correction logic, with automatic error logging and interrupt generation on uncorrectable errors - meeting ASIL-B requirements per ISO 26262 Part 5 Annex D.
Can the dual Cortex-M7 cores operate in lockstep mode for ASIL-D applications?
No - CYT3BB5CEBQ0AEEGS supports lockstep only for individual Cortex-M7 cores (not dual-core lockstep), and is certified for ASIL-B. For ASIL-D, Infineon recommends the CYT4BB variant with enhanced safety mechanisms including dual-core lockstep and additional diagnostic coverage - verified in the CYT4BB safety manual (INFINEON-AN258711).
