Cypress Traveo™ II for Body CYT2B9 Series

Cypress Traveo™ II CYT2B9 series MCUs are designed for automotive body electronics with processing power and network connectivity built into the Arm® Cortex®-M4F.

This series provides higher response and faster communication with the embedded CXPI interface in addition to CAN FD interface, and is ideal for body control modules, HVAC, and lighting. Traveo II devices have advanced security features with the introduction of HSM (Hardware security module), dedicated Cortex®-M0+ for secure processing, and embedded flash in dual bank mode for FOTA requirements.

This family features six power modes that enable ECUs to minimize overall power consumption and cutting-edge security features for secure communication with the great scalability in memory size and pin count.

Our MCUs come with optimized software platform that is available for Cypress AUTOSAR MCAL (Microcontroller Abstraction Layer), self-test libraries, Flash EEPROM emulation, as well as security low level drivers, combined with third-party firmware.
