Product details
Overview
CYT4BFCCJDQ0BZEGST 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 CYT4BFCCJDQ0BZEGST datasheet, CYT4BFCCJDQ0BZEGST pinout, CYT4BFCCJDQ0BZEGST application, or CYT4BFCCJDQ0BZEGST equivalent, key selection criteria include dual-core M7/M0+ partitioning, 10-channel CAN FD support, IEEE-802.3az-compliant Ethernet MAC with RGMII/GMII, eSHE/HSM security engine, and 240 GPIO with Smart I/O capability.
Technical Context
The device implements a heterogeneous multi-CPU architecture: two lockstep-capable Cortex-M7 cores handle real-time control and signal processing, while the Cortex-M0+ manages peripheral offload and security services including secure boot verification and cryptographic operations via dedicated hardware accelerators for AES-128/192/256, SHA-256/512, RSA/ECC, and TRNG.
Safety-critical operation is enforced by SMPU, PPU, SECDED ECC on flash/SRAM/TCM, dual-threshold BOD (2.7 V/3.0 V on VDDD/VDDA), MCWDT, and CSV-enabling compliance with ISO 26262 ASIL-B requirements for automotive body electronics without external safety monitors.

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 320-MHz Arm® Cortex®-M7 core; no M0+ companion core; 4 MB flash; supports CAN FD (8 ch), Ethernet (1x 1000BASE-T1), no FlexRay. | Lacks FlexRay and dual-core partitioning; suitable for non-FlexRay gateways or simpler BCMs without security offload. | Select when FlexRay is unused and HSM-level security is handled externally or via software-only TLS stacks. |
| Renesas RH850/U2A | 32-bit RXv3 core (not Arm); 8 MB flash; CAN FD (12 ch), Ethernet (1x 1000BASE-T1), FlexRay (2 ch); ASIL-D capable but no integrated HSM. | Non-Arm ISA limits toolchain compatibility; higher flash density but no hardware-accelerated crypto engine or eSHE. | Prefer for legacy RH850 ecosystem projects requiring ASIL-D or where vendor-specific compiler/toolchain integration is mandated. |
Compared with NXP S32K344 and Renesas RH850/U2A, CYT4BFCCJDQ0BZEGST uniquely combines dual Arm M7/M0+ cores, integrated HSM/eSHE, FlexRay v2.1, and dual Ethernet MACs-making it optimal for next-gen automotive gateways requiring hardware-enforced security partitioning and multi-protocol bridging.

FAQ
What is the maximum operating frequency of the Cortex-M7 cores in CYT4BFCCJDQ0BZEGST?
The dual Arm® Cortex®-M7 CPUs operate at up to 350 MHz each, with individual 16-KB instruction and data caches, single-cycle multiply, and single/double-precision FPU support. This frequency is sustained under full ASIL-B safety monitoring with MPU and SMPU enabled, as validated in Infineon's functional safety documentation for this part number.
Does CYT4BFCCJDQ0BZEGST support IEEE-1588 Precision Time Protocol?
Yes, both integrated Ethernet MAC interfaces support IEEE-1588 PTP for sub-microsecond time synchronization across automotive networks. Hardware timestamping is implemented in the MAC layer, enabling transparent clock and boundary clock operation without CPU intervention-critical for audio-video bridging and deterministic control loops.
How many CAN FD channels does CYT4BFCCJDQ0BZEGST support, and what is the maximum data rate?
CYT4BFCCJDQ0BZEGST supports up to 10 CAN FD channels compliant with ISO 11898-1:2015 and Bosch CAN FD v1.0. Each channel achieves up to 8 Mbps data rate in the data phase, limited only by external transceiver performance and physical layer topology-not by the MCU's internal controller bandwidth.
Is external flash required for XIP operation, and what encryption is supported?
No external flash is required for XIP-the device supports Execute-In-Place directly from its internal 8384 KB code-flash. When using external memory via SPI or HYPERBUS™, on-the-fly AES-128 encryption/decryption is performed in hardware, ensuring firmware confidentiality without performance penalty during boot or runtime code fetch.
