Product details
Overview
CYT4DNJBACQ1BZSGS from Infineon 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 FPD-Link dual output (2880 × 1080 @ 220 MHz), targeting instrument clusters and HUD systems.
For engineers reviewing the CYT4DNJBACQ1BZSGS datasheet, CYT4DNJBACQ1BZSGS pinout, CYT4DNJBACQ1BZSGS application, or CYT4DNJBACQ1BZSGS equivalent, key selection criteria include dual-core deterministic real-time execution, ASIL-B functional safety compliance, on-the-fly JPEG decoding, hardware-accelerated graphics composition, and secure boot with eSHE/HSM support.
Technical Context
The CYT4DNJBACQ1BZSGS implements a heterogeneous multi-CPU architecture: two lockstep-capable Cortex®-M7 cores for primary application processing and a dedicated Cortex®-M0+ core for peripheral management and security services. Its system-level safety features include SMPU, PPU, SECDED ECC on all safety-critical memories, and MCWDT.
Graphics subsystem operates at 40-bit internal precision (RGBA 10-bit) with direct capture-to-display video feed, on-the-fly warping, and command-sequenced rendering-enabling HUD-specific real-time distortion correction without frame buffers. The SMIF supports octal SPI, XIP, and on-the-fly encryption for secure external memory access.
