Product details
Overview
CYT4BFCCHDQ0BZEGST 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 (up to 20 channels). It targets high-end body-control units requiring ASIL-B functional safety, secure boot, and hardware cryptography acceleration.
For engineers reviewing the CYT4BFCCHDQ0BZEGST datasheet, CYT4BFCCHDQ0BZEGST pinout, CYT4BFCCHDQ0BZEGST application, or CYT4BFCCHDQ0BZEGST equivalent, this page delivers verified technical context, package mapping, real-world use cases, and validated alternative options for automotive ECU design and firmware-over-the-air (FOTA) deployment.
Technical Context
The device implements a heterogeneous multi-core architecture with hardware inter-processor communication between two Cortex-M7 cores and one Cortex-M0+ core, enabling separation of safety-critical peripheral management from primary application processing. Memory subsystem includes SECDED ECC on all safety-critical memories (SRAM, flash, TCM), RWW flash operation, and dual-bank flash for atomic FOTA updates.
Clock system integrates IMO, ILO, ECO, WCO, PLL, and FLL with CSV supervision; power management supports five low-power modes (Active, Sleep, Low-power Sleep, DeepSleep, Hibernate) with configurable BOD thresholds (2.7 V/3.0 V on VDDD/VDDA, 1.1 V on VCCD) and wakeup via up to 240 GPIOs or dedicated event generators.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K344 | Single 320-MHz Arm® Cortex®-M7 core; no Cortex-M0+ companion core; 4 MB flash; supports CAN FD (12 ch), Ethernet (1x 1000BASE-T1), but lacks FlexRay. | Better suited for mid-tier gateway or chassis ECUs where FlexRay is not required and single-core determinism suffices. | Select when FlexRay integration is unnecessary and cost-sensitive BOM optimization is prioritized over dual-core safety partitioning. |
| Renesas RH850/U2A | 32-bit RXv3 core (not Arm); 12 MB flash; supports CAN FD (16 ch), Ethernet (1x 1000BASE-T1), FlexRay (2 ch); ASIL-D capable but no integrated HSM. | Targeted at powertrain and brake ECUs requiring highest ASIL-D compliance and larger code footprint, with external crypto co-processor needed. | Choose when ASIL-D certification is mandatory and legacy RX ecosystem integration outweighs Arm toolchain advantages. |
Compared with S32K344 and RH850/U2A, CYT4BFCCHDQ0BZEGST uniquely combines dual Cortex-M7 cores with integrated HSM and FlexRay-making it optimal for high-end body/gateway ECUs needing both safety partitioning and multi-protocol bridging without external security chips.

FAQ
What is the maximum operating frequency of the Cortex-M7 cores in CYT4BFCCHDQ0BZEGST?
The dual Arm® Cortex®-M7 CPUs operate at up to 350 MHz each, with single-cycle multiply, FPU, and 16-KB instruction/data caches. This frequency is guaranteed across the full industrial temperature range (–40°C to +125°C) and supported by the internal PLL with CSV monitoring for clock stability validation.
Does CYT4BFCCHDQ0BZEGST support secure boot with public-key verification?
Yes-it implements fast secure boot using digital signature verification with RSA or ECC keys stored in OTP eFuse. The HSM validates firmware signatures before execution, and boot images must be signed using private keys corresponding to public keys fused into the device during manufacturing.
How many CAN FD channels does CYT4BFCCHDQ0BZEGST support, and what is the maximum data rate?
CYT4BFCCHDQ0BZEGST supports up to 10 CAN FD channels compliant with ISO 11898-1:2015 and Bosch CAN FD v1.0. The theoretical maximum data rate is 8 Mbps, though actual performance depends on transceiver capabilities, bus topology, and termination-verified per ISO 16845:2015 conformance testing.
Is external memory interface supported, and what protocols are available?
Yes-the device includes one configurable interface supporting either SPI (single/dual/quad/octal) or HYPERBUS™ protocols. It enables Execute-In-Place (XIP) from external memory and supports on-the-fly encryption/decryption using the integrated HSM, allowing secure expansion of code and data space beyond on-chip flash/SRAM.
