Product details
Overview
CYT4DNJBHCQ1BZSGS from Infineon is a TRAVEO™ T2G 32-bit automotive microcontroller with dual Arm® Cortex®-M7 CPUs (320 MHz), one Cortex®-M0+ CPU (100 MHz), 6336 KB code-flash, 640 KB SRAM, and integrated 2D/2.5D graphics engine supporting dual FPD-Link outputs up to 2880 × 1080 at 220 MHz. It targets instrument clusters and HUD systems requiring real-time rendering, secure boot, and ASIL-B functional safety.
For engineers reviewing the CYT4DNJBHCQ1BZSGS datasheet, CYT4DNJBHCQ1BZSGS pinout, CYT4DNJBHCQ1BZSGS application, or CYT4DNJBHCQ1BZSGS equivalent, key selection criteria include dual-display timing support, CAN FD + Ethernet AVB connectivity, hardware-accelerated JPEG decode, eSHE/HSM crypto engine, and fine-grained power modes including Hibernate with 10-pin wakeup capability.
Technical Context
The device implements a heterogeneous multi-core 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. Inter-processor communication is hardware-accelerated via dedicated mailbox and shared memory interfaces.
Graphics subsystem includes a command sequencer, drawing engine, composition engine, and display warping logic - all operating without frame buffers for HUD on-the-fly distortion correction. The JPEG decoder supports ISO/IEC 10918-1 subset decoding with YUV 4:2:0/4:2:2/4:4:4 input and pixel output up to 16384 × 16384.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP S32K388 | Single Cortex®-M7 @ 320 MHz, no integrated graphics engine, 4 MB flash, supports ASIL-D but lacks JPEG decode and FPD-Link. | Targeted at safety-critical powertrain and chassis control; not suitable for dual-display HUD/instrument cluster UI rendering. | Select when functional safety level exceeds ASIL-B and graphics acceleration is unnecessary. |
| Renesas RH850/U2A | Tri-core (RH850 + 2x G3MH), 16 MB flash, no hardware JPEG decode, no FPD-Link, supports ASIL-D but requires external GPU for HUD. | Focused on high-integrity motor control and brake-by-wire; relies on external components for display pipeline and image processing. | Select when legacy AUTOSAR Classic compatibility and ultra-high reliability outweigh integrated graphics cost savings. |
