Product details
Overview
CYT4BFCCHDQ0BZSGS 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 with RWW support, 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 CYT4BFCCHDQ0BZSGS datasheet, CYT4BFCCHDQ0BZSGS pinout, CYT4BFCCHDQ0BZSGS application, or CYT4BFCCHDQ0BZSGS equivalent, this MCU delivers deterministic real-time control, multi-domain security isolation via dedicated M0+ subsystem, and flexible peripheral routing for complex automotive domain controllers.
Technical Context
The CYT4BFCCHDQ0BZSGS implements a heterogeneous dual-core architecture where two Cortex-M7 cores handle primary application processing with independent 16-KB I/D caches and TCM, while the Cortex-M0+ manages peripheral offload, security services, and inter-processor communication via hardware mailbox. Memory subsystem includes SECDED ECC on all safety-critical memories (flash, SRAM, TCM) and dual-bank flash supporting FOTA updates.
Its communication stack integrates 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/MII/RMII PHY support, and a V2.1 FlexRay controller configurable for single/dual-channel fault-tolerant operation up to 10 Mbps.

FAQ
What is the maximum operating frequency of the Cortex-M7 cores in CYT4BFCCHDQ0BZSGS?
The dual Arm® Cortex®-M7 CPUs operate at up to 350 MHz each, with independent 16-KB instruction and data caches, 16-KB TCM, and single-cycle multiply/FPU support. This frequency is sustained under automotive temperature range (−40°C to 125°C) with appropriate voltage and thermal management per Infineon's datasheet specifications.
Does CYT4BFCCHDQ0BZSGS support IEEE-1588 Precision Time Protocol?
Yes, both Gigabit Ethernet MAC interfaces comply with IEEE-1588 PTP for sub-microsecond time synchronization across distributed automotive networks. Hardware timestamping is implemented in the MAC layer, enabling accurate time-aware scheduling and AVB stream alignment without CPU overhead.
How many CAN FD channels does CYT4BFCCHDQ0BZSGS support, and what is the maximum data rate?
CYT4BFCCHDQ0BZSGS supports up to 10 CAN FD channels, each capable of up to 8 Mbps data rate under ISO 11898-1:2015 compliance. Actual achievable rate depends on physical layer topology and transceiver selection, but the controller fully implements Bosch CAN FD v1.0 non-ISO features including flexible data phase length and CRC coverage.
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 SPI or HYPERBUS™ devices. Encryption keys are stored in protected eFuses or HSM-managed key slots; the crypto engine operates transparently during XIP execution, ensuring confidentiality without software intervention or performance penalty.
