CYT4BF
TRAVEO™ T2G 32-bit Automotive MCU
Based on Arm® Cortex®-M7 dual
General description
CYT4BF is a family of TRAVEO™ T2G microcontrollers targeted at automotive systems such as high-end
body-control units. CYT4BF has 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 Controller Area
Network with Flexible Data rate (CAN FD), Local Interconnect Network (LIN), Gigabit Ethernet, and FlexRay.
TRAVEO™ T2G devices are manufactured on an advanced 40-nm process. CYT4BF incorporates a low-power flash
memory, multiple high-performance analog and digital peripherals, and enables the creation of a secure
computing platform.
