Product details
Overview
CYT4BF8CEDQ0AESGST from Infineon is a TRAVEO™ T2G 32-bit automotive microcontroller featuring dual 350-MHz Arm® Cortex®-M7 CPUs and one 100-MHz Arm® Cortex®-M0+ CPU, 8384 KB code-flash, 1024 KB SRAM, and integrated CAN FD (up to 10 channels), Gigabit Ethernet MAC, FlexRay, and LIN interfaces. It targets high-end body-control units requiring ASIL-B functional safety, secure boot, and hardware cryptography acceleration.
For engineers reviewing the CYT4BF8CEDQ0AESGST datasheet, CYT4BF8CEDQ0AESGST pinout, CYT4BF8CEDQ0AESGST application, or CYT4BF8CEDQ0AESGST equivalent, this MCU delivers deterministic real-time control with dual-core isolation, RWW flash for FOTA updates, hardware ECC on all safety-critical memories, and configurable low-power modes down to Hibernate.
Technical Context
The CYT4BF8CEDQ0AESGST implements a heterogeneous multi-CPU architecture: two lockstep-capable Cortex-M7 cores handle primary application tasks with independent 16-KB I/D caches and TCM, while the Cortex-M0+ manages peripheral offload and security services including eSHE/HSM. Inter-processor communication is handled via dedicated hardware mailboxes and shared memory with SMPU enforcement.
Its safety architecture includes SECDED ECC on flash, SRAM, and TCM; MPU/SMPU/PPU protection units; MCWDT and CSV clock supervision; and BOD/OVD/LVD monitoring across VDDD, VDDA, and VCCD rails - all certified for ASIL-B compliance per ISO 26262.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S32K344 | Single 320-MHz Arm® Cortex®-M7 core; no integrated Ethernet MAC; 6 MB flash; supports ASIL-D via lockstep | Better suited for safety-critical powertrain where Ethernet is unnecessary and ASIL-D is mandatory | Select when Ethernet connectivity is not required and higher ASIL level is prioritized over multi-protocol integration |
| TC397 | Dual 300-MHz TriCore™ cores; 8 MB flash; no native CAN FD or Ethernet; supports ASIL-D with lockstep and ECC | Targeted at chassis and powertrain control with legacy TriCore toolchain dependency and no Ethernet PHY interface | Select when existing TriCore ecosystem and maximum ASIL-D coverage outweigh need for modern networking peripherals |
Compared with S32K344 and TC397, CYT4BF8CEDQ0AESGST uniquely combines dual M7 performance, integrated Gigabit Ethernet with PTP, CAN FD, and FlexRay in a single ASIL-B device - making it optimal for next-gen gateways and domain controllers where protocol convergence and FOTA readiness are essential.

FAQ
What is the maximum operating frequency of the Cortex-M7 cores in CYT4BF8CEDQ0AESGST?
The dual Arm® Cortex®-M7 CPUs operate at up to 350 MHz each, with independent instruction and data caches (16 KB each), tightly coupled memories (16 KB ITCM + 16 KB DTCM), and single-cycle multiply/FPU support. This frequency is sustained across the full industrial temperature range (-40°C to +125°C) under specified voltage and thermal conditions.
Does CYT4BF8CEDQ0AESGST support IEEE-1588 Precision Time Protocol?
Yes - both integrated Gigabit Ethernet MAC interfaces support IEEE-1588 PTP with hardware timestamping, enabling sub-microsecond time synchronization across vehicle networks. The MACs support all PTP profiles including transparent clock and boundary clock operation when paired with compliant PHYs.
How many CAN FD channels does CYT4BF8CEDQ0AESGST support, and what is the maximum data rate?
CYT4BF8CEDQ0AESGST supports up to 10 CAN FD channels, each compliant with ISO 11898-1:2015 and capable of data rates up to 8 Mbps in the fast phase. Physical layer limitations (transceiver and topology) apply, but the controller itself meets Bosch CAN FD v1.0 specification requirements for non-ISO implementations.
Is external memory encryption supported, and how is it implemented?
Yes - the external memory interface supports on-the-fly AES-128 encryption and decryption for data transferred over SPI or HYPERBUS™. Encryption keys are stored in secure OTP eFuses and managed exclusively by the HSM; plaintext never appears on the external bus, enabling secure XIP execution from untrusted memory devices.
