Product details
Overview
CYT4BB7CEBQ0AESGST from Infineon is a TRAVEO™ T2G 32-bit automotive microcontroller featuring dual Arm® Cortex®-M7 CPUs (250 MHz), one Arm® Cortex®-M0+ CPU (100 MHz), 4160 KB code-flash, 768 KB SRAM, and integrated CAN FD (up to 8 Mbps), Ethernet MAC (10/100 Mbps), and LIN (16 channels). It targets high-end body-control units requiring ASIL-B functional safety compliance, secure boot, and hardware cryptography acceleration.
For engineers reviewing the CYT4BB7CEBQ0AESGST datasheet, CYT4BB7CEBQ0AESGST pinout, CYT4BB7CEBQ0AESGST application, or CYT4BB7CEBQ0AESGST equivalent, key selection considerations include dual-core deterministic real-time execution, ISO 11898-1:2015–compliant CAN FD timing, IEEE-802.3bw Ethernet MAC with RMII/MII support, eSHE/HSM security enforcement, and 220 GPIO with Smart I/O Boolean logic capability.
Technical Context
The device implements a heterogeneous multi-core architecture: two lockstep-capable Cortex-M7 cores handle primary control and signal processing, while the Cortex-M0+ manages peripheral offload and security services via hardware inter-processor communication. Memory subsystem includes SECDED ECC on all safety-critical memories (flash, SRAM, TCM) and Read-While-Write flash supporting FOTA in dual-bank mode.
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 sources including up to 220 GPIO pins and RTC alarms.

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 @ 320 MHz; 4 MB flash; no integrated Ethernet MAC; uses external PHY for 100BASE-T1 | Lacks native Ethernet MAC; requires external PHY and magnetics for automotive Ethernet | Select when Ethernet is not required or when leveraging existing S32K3 ecosystem and AUTOSAR stack maturity |
| Renesas RH850/U2A | Dual lockstep Cortex-R52 cores; 6 MB flash; 100BASE-T1 PHY integrated; no CAN FD support | Native 100BASE-T1 but limited to classic CAN (not FD); higher core count but less flexible peripheral reconfiguration | Select for pure 100BASE-T1 gateway designs where CAN FD bandwidth is not critical |
Compared with NXP S32K344 and Renesas RH850/U2A, CYT4BB7CEBQ0AESGST uniquely combines dual M7 cores, on-die Ethernet MAC with RMII/MII flexibility, 8-channel CAN FD, and hardware-accelerated crypto in a single ASIL-B–certified package-enabling consolidated domain controllers without external bridge ICs or PHYs.

FAQ
What is the maximum operating frequency of the Cortex-M7 cores in CYT4BB7CEBQ0AESGST?
The dual Arm® Cortex®-M7 cores operate at up to 250 MHz, with single-cycle multiply, single/double-precision FPU, and 16-KB instruction/data caches. This frequency is sustained under full voltage and temperature specifications per Infineon's 002-26591 Rev. *H datasheet, and is validated for ASIL-B operation with MPU and ECC protection enabled.
Does CYT4BB7CEBQ0AESGST support IEEE-1588 Precision Time Protocol?
Yes, the integrated Ethernet MAC fully supports IEEE-1588 PTP with hardware timestamping for transmit and receive frames. It implements PTP event message handling and provides sub-microsecond synchronization accuracy when paired with a compliant PHY, as confirmed in Section 3.3.8 of the official datasheet.
How many CAN FD channels does CYT4BB7CEBQ0AESGST support, and what is their compliance status?
CYT4BB7CEBQ0AESGST supports up to eight CAN FD channels compliant with ISO 11898-1:2015 and the Bosch CAN FD Specification V1.0 (non-ISO). Each channel achieves up to 8 Mbps data rate depending on transceiver and topology, and holds ISO 16845:2015 conformance certification per Infineon's test reports.
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 data transferred over SPI or HYPERBUS™. Encryption keys are stored in protected eFuses and managed by the HSM; XIP (execute-in-place) is enabled without exposing decrypted code to external memory buses, as detailed in Section 3.3.9 of the datasheet.
