Infineon CYT2BL7CAAQ0AZEGS

CYT2BL is part of the TRAVEO T2G microcontroller family, targeting systems such as automotive body control units. This family employs an Arm Cortex-M4F CPU for main processing, paired with an Arm Cortex-M0+ CPU for peripheral and safety processing. These devices integrate embedded peripherals supporting CAN FD, LIN, and CXPI protocols. TRAVEO T2G devices are manufactured using an advanced 40nm process. CYT2BL integrates low-power flash memory, multiple high-performance analog and digital peripherals, and supports the creation of a safe computing platform.
