Microchip is expanding its broad portfolio of dsPIC33C DSCs to cover the large memory segment with its new ISO 26262-compliant dsPIC33CK1024MP7xx family. This family of dsPIC33C DSCs with 1 MB Flash enables applications running automotive software like Autosar, OS, MCAL drivers, ISO 26262 functional safety diagnostics and security libraries. The family of dsPIC33 DSCs also includes a CPU with deterministic response and specialized peripherals for general automotive, advanced sensing and control, digital power and motor control applications.

“The Autosar-ready dsPIC33C DSCs enable designers to achieve a high level of system optimization by implementing Autosar-based applications, functional safety goals and security use cases in a single microcontroller (MCU) while meeting robust automotive application requirements,” said Joe Thomsen, vice president of the MCU16 business unit at Microchip Technology. “This opens up a world of opportunities for designers looking to work with Microchip while expanding into e-mobility and advanced sensing and control applications.”

The benefit of adopting Autosar-ready devices is that customers can improve their risk and complexity management while decreasing development time through reusability. Microchip advertises. Customers who have previously designed bare metal or non-Autosar automotive applications and are now adopting Autosar can scale up by staying within the dsPIC33C DSC ecosystem and continuing to take advantage of Microchip’s value-added solutions, customer support and product advantages with the new Autosar-ready dsPIC33C DSCs. The Autosar ecosystem for the dsPIC33C DSCs includes Microsar Classic from Vector, KSAR OS from KPIT Technologies as well as ASPICE- and ASIL B-compliant MCAL drivers from Microchip.

“The integrated solution gives insights into the Autosar-based development”, says Matthias Kaestner, vice president of Microchip’s automotive products business unit. “It simplifies evaluation of an ECU project using Autosar 4.3.x and enables customers to get familiar with the systems based on dsPIC33 Autosar-ready DSCs quickly.”  

The chipmakler has expanded its functional safety packages that include FMEDA reports, safety manuals and diagnostic libraries to cover the ISO 26262-compliant dsPIC33CK1024MP7xx DSCs. These Autosar-ready dsPIC33C DSCs, used together with Microchip’s TA100 CryptoAutomotive security integrated circuits (ICs), enable the implementation of robust security in automotive designs.

Software and tools from Microchip Technology include certified MPLAB XC16 compiler functional safety licenses, MPLAB X Integrated Development Environment (IDE), MPLAB Code Configurator (MCC), programming and debugging tools for dsPIC33C DSCs, ISO 26262- and ASPICE-compliant MCAL drivers for dsPIC33C DSCs, ISO 26262 functional safety packages for dsPIC33C DSCs and software libraries and reference code for security use cases. Third-party software includes Microsar Classic from Vector and KSAR OS from KPIT Technologies. Third-party hardware tools include the Trace32 debugger from Lauterbach.
