Infineon Technologies CYT4DNJBQCQ1BZSGST

Overview

CYT4DNJBQCQ1BZSGST from Infineon is an automotive-grade 32-bit TRAVEO™ T2G microcontroller featuring dual 320-MHz Arm® Cortex®-M7 CPUs and a 100-MHz Cortex®-M0+ security core, 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 digital instrument cluster applications.

For engineers reviewing the CYT4DNJBQCQ1BZSGST datasheet, CYT4DNJBQCQ1BZSGST pinout, CYT4DNJBQCQ1BZSGST application, or CYT4DNJBQCQ1BZSGST equivalent, key selection criteria include dual-core deterministic real-time performance, ASIL-B functional safety compliance, on-the-fly display warping, secure boot with eSHE/HSM, and multi-display video output with MIPI CSI-2 capture support.

Technical Context

The CYT4DNJBQCQ1BZSGST implements a heterogeneous multi-core architecture: two lockstep-capable Cortex®-M7 cores handle primary graphics and application processing, while the Cortex®-M0+ executes peripheral management and cryptographic operations. Hardware inter-processor communication enables deterministic message passing without software overhead.

Its graphics subsystem includes a dedicated drawing engine, composition engine, and command sequencer-enabling frame-bufferless rendering directly to parallel RGB or dual FPD-Link outputs. The JPEG decoder supports full ISO/IEC10918-1 subset with YUV 4:2:0/4:2:2/4:4:4 and up to 16384×16384 pixel input resolution.

Key Specifications

Pinout & Package

FAQ

What power supply rails does CYT4DNJBQCQ1BZSGST require?

The device requires three primary supplies: VDDD (1.1-V core), VDDA_ADC (1.1-V analog for ADC), and VCCD (1.1-V for digital peripherals). All are generated internally from a single 2.7–5.5-V input. Independent brown-out detection thresholds apply-2.7 V and 3.0 V for VDDD/VDDA_ADC, and 1.1 V for VCCD-ensuring robust startup and fault response across automotive voltage transients.

Does CYT4DNJBQCQ1BZSGST support IEEE-1588 Precision Time Protocol?

Yes, the integrated Gigabit Ethernet MAC fully supports IEEE-1588 PTP in hardware, including timestamping of ingress/egress frames at the MAC layer. It operates with MII, RMII, and RGMII PHY interfaces and complies with IEEE-802.1AS for time-synchronized audio-video bridging-critical for deterministic inter-domain communication in zonal architectures.

How many MIPI CSI-2 lanes does the video capture engine support?

The video capture engine supports either two or four MIPI CSI-2 lanes, selectable at runtime. At 110 MHz per lane, two lanes support up to 1920×720 capture; at 220 MHz per lane, four lanes support up to 2880×1080. Lane count and clock rate are configured via register settings in the MIPI CSI-2 controller block, with automatic protocol alignment and error detection.

Is secure boot implemented in hardware or firmware?

Secure boot is implemented entirely in hardware using the integrated Crypto Engine. It verifies digital signatures (RSA-2048/3072 or ECC NIST P-256/P-384) of the boot image before loading into TCM, enforces AES-128/192/256-GCM decryption of encrypted firmware, and leverages eSHE-compliant key storage. No software intervention is required-the process initiates automatically on reset and is tamper-resistant by design.
