General description
CYT2B6 is a family of TRAVEO™ T2G microcontrollers targeted at automotive systems such as body control units.
CYT2B6 has an Arm® Cortex®-M4 CPU 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), and Local Interconnect Network (LIN). TRAVEO™ T2G devices are manufactured on
an advanced 40-nm process. CYT2B6 incorporates a low-power flash memory, multiple high-performance analog
and digital peripherals, and enables the creation of a secure computing platform.
