Product details
Overview
CYT4BFBCJDQ0BZSGST from Infineon is a dual-core automotive MCU featuring two 350-MHz Arm® Cortex®-M7 CPUs and one 100-MHz 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 CYT4BFBCJDQ0BZSGST datasheet, CYT4BFBCJDQ0BZSGST pinout, CYT4BFBCJDQ0BZSGST application, or CYT4BFBCJDQ0BZSGST equivalent, this page delivers verified technical context, package mapping, real-world use cases, and validated alternative parts for automotive ECU design and FOTA-capable systems.
Technical Context
The CYT4BFBCJDQ0BZSGST implements a heterogeneous multi-CPU architecture: dual Cortex®-M7 cores operate at 350 MHz with independent 16-KB I/D caches and TCM, while the Cortex®-M0+ handles peripheral offload and security services at 100 MHz. All CPUs share hardware inter-processor communication and are protected by SMPU, PPU, and SECDED ECC on flash/SRAM/TCM.
Its peripheral subsystem includes three DMA controllers (P-DMA0: 143 channels, P-DMA1: 65, M-DMA0: 8), up to 10 CAN FD channels compliant with ISO 11898-1:2015 and Bosch CAN FD v1.0, two IEEE-802.3az-compliant Gigabit Ethernet MACs with RGMII/GMII support, and a FlexRay V2.1 interface supporting dual-channel fault-tolerant operation at up to 10 Mbps.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K344 | Single 320-MHz Arm® Cortex®-M7 core; no integrated Ethernet MAC; supports CAN XL instead of FlexRay | Better suited for chassis/safety domains with CAN XL adoption; lacks native Gigabit Ethernet bridging capability | Select when Ethernet gateway functionality is not required and CAN XL ecosystem integration is prioritized |
| Renesas RH850/U2A | 400-MHz RH850 core (not Arm); 6 MB flash; no HSM or AES hardware acceleration; supports CAN FD and Ethernet but no FlexRay | Stronger legacy automotive toolchain support; limited cryptographic agility for evolving OTA security requirements | Select for brownfield designs requiring pin-for-pin compatibility with existing RH850-based platforms |
