Infineon Technologies CYT3BB/CYT4BB TRAVEO™ T2G 32-bit Automotive MCUs

Infineon Technologies CYT3BB/CYT4BB TRAVEO™ T2G 32-bit Automotive MCUs target automotive systems such as high-end body-control units. CYT3BB and CYT4BB features one or two Arm® Cortex®-M7 CPUs for primary processing and an Arm Cortex-M0+ CPU for peripheral and security processing. These devices contain embedded peripherals supporting a Controller Area Network with Flexible Data (CAN FD) rate, a Local Interconnect Network (LIN), and Ethernet. TRAVEO™ T2G devices are manufactured on an advanced 40nm process. CYT3BB/4BB incorporates a low-power flash memory and multiple high-performance analog and digital peripherals. The low-power consumption Infineon Technologies CYT3BB and CYT4BB TRAVEO T2G 32-bit Automotive MCUs enable the creation of a secure computing platform.
