Infineon Technologies has launched a family of automotive microcontrollers (MCU) with a new graphic engine that can provide the same performance as an MPU.

The graphics engine in the TRAVEO T2G Cluster MCU uses a smart rendering technology to provide the performance with simpler OEM integration and reduce BOM costs. This is aimed at smart mobility instrument cluster and heads-up display systems for automobiles, motorcycles, and off highway mobility as well as for industrial and medical applications where quality and safety are important.

The graphics engine within the MCUs minimizes the memory required for graphics processing by a factor of 3 to 5, resulting in lower power consumption and lower costs. With the optimized 2.5 D graphics engine, the MCUs support full virtual instrument clusters with a high resolution of up to 1920 x 1080.

The family has up to two Arm Cortex-M7 cores with up to 320 MHz, the TRAVEO T2G Cluster Microcontroller family enables best in class ASIL-B/SIL-2 safety performance. The MCU family comes with up to 6MB of Flash and up to 4MB of internal VRAM or 1GB LPPDR4 VRAM.The MCUs are equipped with a EVITA high-level HSM providing advanced security with hardware encryption accelerators and enhanced hardware protection with a dedicated ARM Cortex-M0+.

The range of packages spans from from 500-pin BGA (via 216-pin TEQFP) to 144-pin LQFP. CAN-FD, LIN, Gigabit Ethernet and CXPI are available as embedded peripherals. A JPEG decoder, video input and output and two serial memory interfaces (SPI or xSPI) round off the portfolio.

The devices can be combined with processors in intelligent cockpits to provide a very fast startup time. Engineering samples are already available of a new T2G-C series MCU. It features an LPDDR4 interface and can display complex 3D scenes, giving designers even more freedom in designing modern HMIs.

“The TRAVEO T2G cluster microcontroller family with its dedicated graphics accelerator enables cluster, infotainment and cockpit systems with microprocessor performance at MCU cost”, said Ralf Koedel, Vice President Microcontroller Smart Mobility at Infineon.

“The MCU family uses innovative line-based processing based on an Infineon patent, which enables significant line buffer savings by a factor of 10 compared to competitive devices, resulting in lower power consumption, less memory needs and lower BOM cost.”

The TRAVEO T2G CYT2CL series (ARM Cortex-M4F core at 160 MHz, 4 MB of embedded flash), the TRAVEO T2G CYT3DL series (ARM Cortex-M7F core at 240 MHz, 4 MB of embedded flash and 2 MB VRAM) and the TRAVEO T2G CYT4DN series (Dual ARM Cortex-M7F core at 320 MHz, 6 MB of embedded flash and 4MB VRAM ) are available and can be ordered now.

Engineering samples of the TRAVEO T2G CYT4EN (Dual ARM Cortex-M7F core at 320 MHz, 6 MB of embedded flash, LPDDR4 and eMMC interface) are also available.
