The TRAVEO™ CYT4DN is a family of TRAVEO™ T2G microcontrollers dedicated to automotive systems such as instrument clusters and Head-Up Displays (HUD). The family features a 2D graphics engine, sound processing, two Arm® Cortex®-M7 CPUs for primary processing running up to 320 MHz and an Arm® Cortex®-M0+ CPU for peripheral and security processing. In addition, it includes a 720p GFX and a unique package: 327-ball BGA.

The TRAVEO™ T2G CYT4DN family products contain embedded peripherals supporting controller area network with flexible data rate (CAN FD), local interconnect network (LIN), clock extension peripheral interface (CXPI), and gigabit Ethernet. In terms of memory, it features a line-based 4 MB VRAM, a 6 MB flash and a 640 KB RAM.

The devices are manufactured on an advanced 40-nm process. The TRAVEO™ T2G CYT4DN incorporates Infineon's low-power flash memory, multiple high-performance analog and digital peripherals, and enables the creation of a secure computing platform.
