Infineon Technologies CYT4DNJBMCQ1BZSGST

Overview

CYT4DNJBMCQ1BZSGST from Infineon Technologies is a TRAVEO™ T2G 32-bit automotive microcontroller featuring dual 320-MHz Arm® Cortex®-M7 CPUs, one 100-MHz 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), and dual FPD-Link for HUD and instrument cluster applications.

For engineers reviewing the CYT4DNJBMCQ1BZSGST datasheet, CYT4DNJBMCQ1BZSGST pinout, CYT4DNJBMCQ1BZSGST application, or CYT4DNJBMCQ1BZSGST equivalent, key selection criteria include ASIL-B functional safety compliance, on-the-fly JPEG decoding, hardware-accelerated vector graphics rendering, and dual-display video output with real-time warping support.

Technical Context

The CYT4DNJBMCQ1BZSGST implements a heterogeneous multi-core architecture: two high-performance Cortex-M7 cores handle primary application and graphics processing, while the Cortex-M0+ manages peripheral control, security boot, and HSM operations. Inter-processor communication is handled via dedicated hardware messaging units and shared memory with SMPU protection.

Its graphics subsystem includes a command sequencer, composition engine, drawing engine, and display timing generator - enabling frame-bufferless rendering directly to parallel RGB or dual FPD-Link outputs. The crypto engine supports AES-128/192/256, SHA-256/512, ECC, RSA, and GCM mode, all certified under eSHE and HSM frameworks for secure boot and OTA firmware updates.

FAQ

What is the maximum resolution supported by the dual FPD-Link interface?

The dual FPD-Link interface supports up to 2880 × 1080 pixels at 220 MHz, enabling Wide-HD output for HUD applications. This resolution is achieved using four-lane MIPI CSI-2 input feeding into the composition engine, then routed through two independent FPD-Link transmitters - each operating at 110 MHz with embedded clock recovery.

Does CYT4DNJBMCQ1BZSGST support hardware-accelerated AES-GCM encryption?

Yes, the integrated crypto engine supports AES-128/192/256 in Galois/Counter Mode (GCM) with hardware-accelerated authentication and encryption. Throughput exceeds 100 MB/s for 128-bit keys, and the engine operates independently of the CPU cores - enabling concurrent secure OTA updates and real-time CAN FD message signing.

How many CAN FD channels does this MCU provide, and what is their data rate capability?

CYT4DNJBMCQ1BZSGST provides four fully independent CAN FD channels compliant with ISO 11898-1:2015. Each channel supports data rates up to 8 Mbps in the data phase, with bit-rate switching between arbitration (≤1 Mbps) and data phases - subject to physical layer limitations imposed by external transceivers and bus topology.

Is the 4096 KB VRAM accessible by both Cortex-M7 cores simultaneously?

Yes, the 4096 KB embedded video RAM is mapped into the AXI bus matrix and accessible by both Cortex-M7 cores with cache-coherent DMA transfers. Memory coherency is maintained via hardware snoop logic, allowing one core to render graphics while the other processes sensor fusion data - without software-managed cache flushes or locks.
