Product details
Overview
CYT4DNJBGCQ1BZSGS from Infineon is a TRAVEO™ T2G 32-bit automotive microcontroller featuring dual 320-MHz Arm® Cortex®-M7 CPUs and one 100-MHz Arm® Cortex®-M0+ CPU, 6336-KB code-flash, 640-KB SRAM, and integrated 2D/2.5D graphics engine with 4096 KB VRAM. It supports CAN FD (up to 8 Mbps), Gigabit Ethernet (IEEE-802.3az), FPD-Link dual (2880 × 1080 @ 220 MHz), and JPEG decoding for HUD and instrument cluster systems.
For engineers reviewing the CYT4DNJBGCQ1BZSGS datasheet, CYT4DNJBGCQ1BZSGS pinout, CYT4DNJBGCQ1BZSGS application, or CYT4DNJBGCQ1BZSGS equivalent, key selection criteria include dual-core deterministic real-time execution, ASIL-B functional safety support, on-the-fly graphics composition without frame buffers, and secure boot with HSM/eSHE crypto acceleration.
Technical Context
The CYT4DNJBGCQ1BZSGS implements a heterogeneous multi-CPU architecture: two lockstep-capable Cortex-M7 cores handle primary graphics and application processing, while the Cortex-M0+ manages peripheral control, security services, and low-latency I/O handling. Hardware inter-processor communication enables deterministic message passing between domains.
Its graphics subsystem integrates a command sequencer, drawing engine, composition engine, and display timing generator - all operating independently of CPU intervention. The JPEG decoder supports ISO/IEC 10918-1 subset decoding with YUV 4:2:0/4:2:2/4:4:4 input and up to 16384×16384 pixel output resolution.

|---|---|
|
Use Scenario: Real-time rendering of speed, navigation, ADAS alerts, and vehicle status onto TFT-LCD clusters with animated transitions. IC Role / Device Role / Timing Role: Primary application processor and graphics controller - executes AUTOSAR Adaptive stack while driving dual-display output with sub-16-ms latency. Use Value: Dual M7 cores enable concurrent UI rendering and CAN FD data aggregation; VRAM-based composition avoids external DRAM, reducing BOM cost and EMI. |
Use Scenario: Projection of AR navigation cues, speed, and collision warnings onto windshield with perspective warping and real-time distortion correction. IC Role / Device Role / Timing Role: Graphics timing master and video pipeline orchestrator - synchronizes MIPI CSI-2 camera input, JPEG-decoded map tiles, and FPD-Link output with <50-μs jitter. Use Value: On-the-fly warping engine eliminates need for GPU co-processor; integrated JPEG decode accelerates map tile loading without CPU overhead. |
| Automotive Telematics Gateway | Central Domain Controller (CDC) |
|
Use Scenario: Secure aggregation and routing of cellular, CAN FD, LIN, and Ethernet traffic between infotainment, ADAS, and cloud services. IC Role / Device Role / Timing Role: Network convergence hub with HSM-enforced TLS termination, firewall policy enforcement, and time-synchronized packet forwarding. Use Value: Integrated Gigabit Ethernet MAC with IEEE-1588 PTP and AVB support enables deterministic OTA updates and synchronized diagnostics across ECUs. |
Use Scenario: Consolidation of body control, HVAC, lighting, and chassis functions into a single high-integrity domain controller running mixed-criticality software. IC Role / Device Role / Timing Role: Safety-certified compute platform with partitioned M7/M0+ execution domains - isolates ASIL-B control logic from non-safety UI services. Use Value: Hardware-enforced memory protection (MPU/SMPU/PPU) and SECDED ECC allow SIL2/ASIL-B certification without software-only safety layers. |
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 integrated graphics engine, 4 MB flash, 1.5 MB SRAM, supports CAN FD & Ethernet but lacks JPEG decode and VRAM | Targeted at gateway and chassis control - not suitable for HUD/instrument cluster graphics rendering | Select when graphics acceleration is unnecessary and functional safety focus is on control-loop determinism rather than display integrity |
| Renesas RH850/U2A | 400-MHz RH850 core (not Arm), 8 MB flash, 2 MB SRAM, ASIL-D capable, no integrated graphics or Ethernet MAC, relies on external PHY and GPU | Used in powertrain and brake control where extreme reliability outweighs multimedia capability | Choose for ASIL-D powertrain applications requiring legacy toolchain compatibility and long-term automotive qualification - not for display-centric use cases |
Compared with S32K344 and RH850/U2A, CYT4DNJBGCQ1BZSGS uniquely integrates dual M7 cores, on-chip VRAM, JPEG decode, and FPD-Link - delivering full HUD/instrument cluster functionality in a single package without external graphics or memory components.

FAQ
Does CYT4DNJBGCQ1BZSGS support ISO 26262 ASIL-B certification out of the box?
Yes. CYT4DNJBGCQ1BZSGS includes hardware-level safety mechanisms - SMPU, PPU, MCWDT, SECDED ECC on flash/SRAM/TCM, and dual-core lockstep support - validated per ISO 26262 Part 5. Infineon provides ASIL-B safety manual, FMEDA report, and diagnostic software library to accelerate certification.
What display interfaces does CYT4DNJBGCQ1BZSGS support for dual-display HUD + cluster configurations?
CYT4DNJBGCQ1BZSGS supports simultaneous dual-display output via FPD-Link dual (2880 × 1080 @ 220 MHz) for HUD projection and parallel RGB (1600 × 600 @ 80 MHz) for LCD cluster - both driven from internal VRAM without external frame buffer memory.
Can the JPEG decoder process camera-captured images in real time for AR navigation overlays?
Yes. The hardware JPEG decoder supports YUV 4:2:0/4:2:2 input up to 1920 × 720 at 60 fps (two-lane MIPI CSI-2), enabling real-time decoding of forward-facing camera streams for AR navigation - decoded pixels feed directly into the composition engine for overlay rendering.
Is external RAM required for graphics rendering in CYT4DNJBGCQ1BZSGS-based HUD designs?
No. The device integrates 4096 KB of dedicated VRAM and supports on-the-fly graphics composition without frame buffers - eliminating external DDR/DDR3 and reducing PCB layer count, EMI, and power consumption in space-constrained HUD modules.
