CYT3BB/4BB is a family of TRAVEO™ T2G microcontrollers targeted at automotive systems such as high-end body-control units. CYT3BB/4BB has one or two Arm® Cortex®-M7 CPUs for primary processing, and an Arm® Cortex®-M0+ CPU for peripheral and security processing.
The board provides free options for quick application prototyping and demonstration.
Applications
- Body control module
Features
- Achieve a high - performance, highly secure and highly scalable body control module that meets the ASIL - B functional safety standard and the requirements of the Hardware Security Module (HSM).
- Abundant storage resources: The MCU integrates 4MB of Flash and 512KB of RAM, and there is an external 32MB NOR FLASH, which can meet the needs of large - capacity data storage and the operation of complex programs.
- Rich interfaces: Provide 1 - channel Ethernet interface (ETH) to support high - speed data communication and OTA upgrade functions. Provide 6 channels of CAN FD: Support high - speed networking and data transmission to meet the requirements of intelligent connected vehicles. Provide 1 channel of LIN, which is suitable for low - speed automotive equipment communication. Reserve digital communication interfaces: 2 channels of I2C, 1 channel of SPI, 2 channels of UART, enabling easy interconnection between modules. Provide 6 high - side channels and 8 low - side channels.
Benefits
This body control module has network connectivity and ensures security through HSM, Cortex®-M0+, and dual - bank flash for FOTA. Six power modes can optimize energy consumption, while the expandability of memory/pins enhances flexibility.
It integrates communication interfaces such as CANFD, LIN, HSD, LSD, and SPI. They are highly suitable for regional body control, infotainment, and lighting. A 1 - channel Ethernet interface (ETH) is provided to support high - speed data communication and OTA upgrade functions.
