Product details
Overview
CYT3BB7CEBQ0AESGST 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, secure boot, and hardware cryptography (AES-128/192/256, ECC, SHA-256/512).
For engineers reviewing the CYT3BB7CEBQ0AESGST datasheet, CYT3BB7CEBQ0AESGST pinout, CYT3BB7CEBQ0AESGST application, or CYT3BB7CEBQ0AESGST equivalent, this MCU supports real-time motor control with synchronized 12-bit SAR ADCs (75 ch, 1 Msps), TCPWM blocks (75×16-bit + 8×32-bit), and low-power DeepSleep/Hibernate modes with multi-pin wakeup - critical for automotive ECU design and OTA firmware updates.
Technical Context
The device implements a heterogeneous dual-core architecture: two lockstep-capable Cortex-M7 cores handle primary real-time tasks with 16-KB I/D caches and TCM, while the Cortex-M0+ manages peripheral offload and security services including eSHE/HSM. Hardware inter-processor communication enables deterministic message passing without software overhead.
Its safety subsystem includes MPU, SMPU, PPU, SECDED ECC on all safety-critical memories (flash, SRAM, TCM), MCWDT, and dual-threshold BOD (2.7 V / 3.0 V on VDDD/VDDA; 1.1 V on VCCD), meeting ISO 26262 ASIL-B requirements for automotive body electronics.

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; 4 MB flash; no integrated Ethernet MAC; uses external PHY for 100BASE-T1 | Lacks native Ethernet AVB/PTP - requires additional PHY and layout area for automotive Ethernet compliance | Preferred when CAN FD + LIN + FlexRay dominate, and Ethernet is not required at the ECU level |
| Renesas RH850/U2A | Tri-core (RISC-V + dual RH850); 8 MB flash; ASIL-D capable; no hardware crypto acceleration for ECC/SHA-512 | Higher ASIL rating but longer secure boot time due to software-only crypto - impacts FOTA update window | Selected for chassis/safety-critical systems where ASIL-D certification outweighs crypto performance needs |
Compared with S32K344 and RH850/U2A, CYT3BB7CEBQ0AESGST uniquely integrates Ethernet AVB/PTP, dual-M7 lockstep, and full hardware crypto - making it optimal for gateway and high-end BCM designs requiring time-synchronized networking and fast secure boot.

FAQ
What is the maximum operating frequency of the Cortex-M7 cores in CYT3BB7CEBQ0AESGST?
The dual Arm® Cortex®-M7 cores operate at up to 250 MHz, each with 16-KB instruction and data caches, TCM, and single/double-precision FPU. This frequency is sustained across the full automotive temperature range (−40 °C to 125 °C) under 2.7–5.5 V supply conditions, validated per AEC-Q100 Grade 1.
Does CYT3BB7CEBQ0AESGST support IEEE-1588 Precision Time Protocol?
Yes - its integrated 10/100 Mbps Ethernet MAC fully supports IEEE-1588-2008 PTP with hardware timestamping accuracy of ±50 ns, enabling sub-microsecond clock synchronization across vehicle networks for AVB-compliant audio/video streaming and coordinated diagnostics.
How many CAN FD channels does CYT3BB7CEBQ0AESGST provide, and what is their data rate capability?
CYT3BB7CEBQ0AESGST supports up to eight CAN FD channels compliant with ISO 11898-1:2015 and Bosch CAN FD v1.0, with data rates up to 8 Mbps in the FD data phase - subject to physical layer constraints (transceiver and cabling), and validated per ISO 16845:2015 conformance testing.
Is external memory encryption supported, and how is it implemented?
Yes - the external memory interface (SPI/HYPERBUS™) supports on-the-fly AES-128 encryption/decryption during read/write operations. Keys are stored in secure OTP eFuses and managed by the HSM, preventing unauthorized access to firmware or configuration data stored in external flash.
