Cypress’ Traveo™ II CYT3BB/4BB series MCUs comes with processing power and network connectivity built into the Arm® Cortex®-M7F single/dual core.
The CYT3BB/4BB series is designed for body control modules, gateway, and infotainment applications. This series supports frequent data changes with faster, more secure communication via Ethernet AVB (Audio Video Bridging), CAN-FD and FlexRay.
These devices also meet broad application needs by embedding High-speedSPI (Single, Dual, Quad, or Octal) or HyperBus™ interface for external memory interface, Secure Digital High Capacity (SDHC) interface supporting embedded MultiMediaCard (eMMC), SecureDigital (SD), or SDIO (Secure Digital Input Output), as well as Inter-IC Sound (I2S) Interfaces implemented for connecting digital audio devices.
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.
