MCUs guarantee clean shift to software-defined EVs


Stellar P automotive MCUs from ST goal electrified drivetrains, in addition to domain-oriented, over-the-air updateable programs for EVs. In accordance with the producer, the Stellar P MCUs are the trade’s first qualifiable units for mannequin yr 2024 automobiles to combine the CAN-XL in-car communication normal. CAN-XL will allow new car platforms to deal with the rising knowledge flows in order that automobiles can function at peak efficiency.

The microcontrollers present real-time and deterministic processing leveraging as much as six 32-bit Arm Cortex-R52 cores—some working in Lockstep mode and others in Cut up-lock mode. As much as 20 Mbytes of embedded nonvolatile phase-change reminiscence allow the MCUs to ship quick learn entry occasions. This reminiscence additionally gives a dual-image storage operate (2×20 Mbytes) for over-the-air reprograming functions.

Constructed on 28-nm FD-SOI course of expertise, the components present quasi-immunity to radiations. Stellar 6 MCUs combine superior timers, together with GMT-4, with superior sign processing, devoted sensor/actuator interfaces, and high-temperature assist as much as a junction temperature of 165°C.

Samples of the Stellar P microcontrollers can be found now for mannequin yr 2024 automobiles.
