Automotive microcontroller supports CAN FD
In 2012, Bosch introduced CAN FD as a seamless upgrade of the classic CAN technology the first time at the International CAN Conference. The FD flavour enables highly reliable vehicle control, taking advantage of higher data rates with only a small impact on current software and applications. Spansion has started to supply MCU products equipped with CAN FD.
In addition to the CAD FD interface operating at 5Mbps, the S6J3110 series comes with a maximum 4MB of flash memory to enable high-level program control, and uses 55nm technology. It also features Secure Hardware Extension (SHE) for network security and improved performance for connected cars, as well as advanced partial wakeup for lowering power consumption.
The Spansion Traveo family of microcontrollers is based on the 32-bit ARM Cortex-R5 core and tailored for a broad range of automotive applications. In May 2014, Spansion introduced the first product of the family, the MB9D560 series for vehicle electrification utilized in hybrid electric vehicles (HEV) and electrical vehicles (EV).
The Traveo S6J3110 series delivers high-speed vehicle communication with CAN FD while retaining compatibility with conventional CAN (maximum 1Mbps). The microcontroller is embedded with Spansion’s flash memory (4MB) as internal memory which enables readout after one wait for access from the CPU.
In addition, the microcontroller is equipped with sophisticated security features, preventing data modification, theft and invalid access to the vehicle network.
