Product details
Overview
CYT4DNJBKCQ1BZSGST from Infineon is an automotive-grade 32-bit TRAVEO™ T2G microcontroller built on Arm® Cortex®-M7 dual-core (320 MHz) and Cortex®-M0+ (100 MHz) architecture, featuring integrated 2D/2.5D graphics engine, CAN FD (up to 8 Mbps), Gigabit Ethernet MAC, and hardware crypto acceleration (AES-128/192/256, SHA-256/512, ECC, RSA). It targets instrument clusters and HUD systems requiring real-time rendering, secure boot, and multi-display support up to 2880 × 1080.
For engineers reviewing the CYT4DNJBKCQ1BZSGST datasheet, CYT4DNJBKCQ1BZSGST pinout, CYT4DNJBKCQ1BZSGST application, or CYT4DNJBKCQ1BZSGST equivalent, key selection criteria include dual-M7 core timing determinism, FPD-Link dual-channel video output capability, ASIL-B functional safety compliance, JPEG decode acceleration, and RWW flash with FOTA-ready dual-bank mode.
Technical Context
The CYT4DNJBKCQ1BZSGST implements a heterogeneous multi-core subsystem: two lockstep-capable Cortex®-M7 CPUs handle primary graphics and application processing with 16-KB I/D caches and 64-KB TCM each, while the Cortex®-M0+ manages peripheral control, security services, and low-power state transitions. Inter-processor communication uses dedicated hardware mailboxes and shared memory with SMPU enforcement.
Its graphics pipeline integrates a command sequencer, drawing engine, composition engine, and display engine - enabling frameless on-the-fly rendering to dual displays without external frame buffers. Video input supports MIPI CSI-2 (2-/4-lane), ITU-R BT.656, or parallel RGB/YUV, with real-time warping for HUD optical correction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive graphics and domain controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K344 | Single Cortex®-M7 core (320 MHz), no integrated graphics engine, 2× CAN FD, no FPD-Link, 2 MB flash | Targeted at body control and gateway functions - lacks HUD-specific warping and dual-display output | Select when graphics offload is handled externally or not required; lower BOM cost but higher system-level integration effort |
| Renesas RH850/U2A | 32-bit RXv3 core (400 MHz), no Arm architecture, no hardware JPEG decoder, 1× CAN FD, no Ethernet MAC | Focused on powertrain and chassis control; lacks multimedia interfaces and ASIL-B-certified graphics pipeline | Prefer for legacy AUTOSAR powertrain ECUs where graphics and Ethernet are irrelevant; not suitable for HUD/instrument cluster convergence |
Compared with S32K344 and RH850/U2A, CYT4DNJBKCQ1BZSGST uniquely integrates dual-M7 graphics processing, FPD-Link dual output, and ASIL-B-certified JPEG decode - making it the only option among the three capable of standalone HUD + cluster dual-display implementation without external ASICs.

FAQ
What is the maximum resolution supported by the FPD-Link dual interface?
The FPD-Link dual interface supports up to 2880 × 1080 pixels at 60 Hz with a 220 MHz pixel clock. This enables simultaneous drive of two high-definition displays - for example, a 1920 × 720 HUD and a 2880 × 1080 main cluster - using separate lanes with independent timing and warping control.
Does CYT4DNJBKCQ1BZSGST support secure boot with public-key verification?
Yes. It implements fast secure boot using digital signature verification with asymmetric cryptography (RSA/ECC) via its hardware crypto engine. Public keys are stored in one-time-programmable (OTP) memory, and signature validation occurs before any user code execution, ensuring chain-of-trust integrity from reset vector.
Can the JPEG decoder process images larger than 4096 × 4096 pixels?
Yes. The hardware JPEG decoder supports image dimensions from 1 × 1 up to 16384 × 16384 pixels, conforming to ISO/IEC 10918-1. It handles YUV444/422/420/411 subsampling and outputs decoded pixel data directly to VRAM or SRAM for overlay composition without CPU intervention.
How many CAN FD channels are implemented, and what is their physical layer compatibility?
CYT4DNJBKCQ1BZSGST integrates four fully independent CAN FD controllers compliant with ISO 11898-1:2015 and Bosch CAN FD Specification V1.0. Each channel supports data rates up to 8 Mbps (dependent on transceiver and topology), and all are certified to ISO 16845:2015 conformance test requirements.
