Product details
Overview
CYT4BF8CEDQ0AEEGST from Infineon is a dual-core automotive microcontroller featuring two 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, and FlexRay interfaces. It targets high-end body-control units requiring ASIL-B functional safety, secure boot, and hardware cryptography acceleration.
For engineers reviewing the CYT4BF8CEDQ0AEEGST datasheet, CYT4BF8CEDQ0AEEGST pinout, CYT4BF8CEDQ0AEEGST application, or CYT4BF8CEDQ0AEEGST equivalent, this MCU delivers deterministic real-time control with dual-core lockstep support, RWW flash for FOTA updates, and hardware-enforced memory protection across TCM, SRAM, and flash.
Technical Context
The device implements a heterogeneous multi-CPU architecture: dual M7 cores operate at 350 MHz with independent 16-KB I/D caches and TCM, while the M0+ handles peripheral offload and security services. Inter-processor communication is hardware-accelerated via dedicated mailbox and semaphore units.
Functional safety is architected at silicon level with SMPU, PPU, SECDED ECC on all safety-critical memories, MCWDT, and dual-threshold BOD (2.7 V/3.0 V on VDDD/VDDA, 1.1 V on VCCD). Clock supervision includes CSV, IMO/ILO/ECO/WCO sources, and PLL/FLL synthesis.

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 core (320 MHz), 8 MB flash, no integrated Ethernet MAC, supports CAN XL | Lacks Gigabit Ethernet and FlexRay; optimized for chassis/safety ECU rather than gateway or ADAS hub | Select when CAN XL adoption is prioritized over Ethernet bandwidth and ASIL-D scalability is not required. |
| Renesas RH850/U2A | Tri-core (400 MHz V850E3 + dual lockstep cores), 12 MB flash, 2x CAN FD, no hardware crypto accelerator | Higher core count but no integrated Ethernet or HSM; relies on external security IC for secure boot | Prefer for legacy RH850 toolchain continuity and ultra-high ASIL-D motor control, where external crypto co-processing is acceptable. |
Compared with S32K344 and RH850/U2A, CYT4BF8CEDQ0AEEGST uniquely integrates dual M7 + M0+ with on-die Gigabit Ethernet, FlexRay, and HSM-enabling consolidated gateway/ADAS designs without external PHYs or security chips, reducing BOM cost and board area.

FAQ
What is the maximum operating frequency of the Cortex®-M7 cores in CYT4BF8CEDQ0AEEGST?
The dual Arm® Cortex®-M7 cores operate at up to 350 MHz each, with independent 16-KB instruction and data caches, 16-KB TCM, and single-cycle multiply capability. This frequency is sustained under automotive temperature range (−40 °C to +125 °C) with appropriate voltage and cooling conditions per Infineon's datasheet specifications.
Does CYT4BF8CEDQ0AEEGST support IEEE-1588 Precision Time Protocol?
Yes, CYT4BF8CEDQ0AEEGST supports IEEE-1588 PTP through its integrated Gigabit Ethernet MAC interfaces. The hardware timestamping unit captures packet arrival/departure times with sub-microsecond resolution, enabling time-synchronized operation across distributed automotive networks such as AVB and TSN.
How many CAN FD channels does CYT4BF8CEDQ0AEEGST provide, and what is the maximum data rate?
CYT4BF8CEDQ0AEEGST supports up to 10 CAN FD channels, each capable of data rates up to 8 Mbps in the data phase. This complies with ISO 11898-1:2015 and the Bosch CAN FD Specification V1.0, subject to physical layer transceiver and topology limitations.
Is external memory encryption supported, and how is it implemented?
Yes, CYT4BF8CEDQ0AEEGST supports on-the-fly encryption and decryption for external memory accessed via SPI or HYPERBUS™ interface. Encryption uses AES-128 in XTS mode, managed by the cryptographic engine without CPU intervention, enabling secure Execute-In-Place (XIP) from external flash while protecting firmware IP.
