Functional safety packages simplify design of ASIL B and ASIL C safety applications

27-10-2021 | Microchip Technology | Automotive Technologies

Microchip Technology now offers newly certified functional safety packages to allow engineers to develop their products as per the ISO 26262 functional safety standard. The company is announcing the release of ISO 26262 functional safety packages for dsPIC33C DSCs, PIC18 and AVR MCUs that speed the development of safety-critical designs aimed at ASIL B and ASIL C safety level and certification efforts.


Whether an engineer is new to ISO 26262 functional safety or a seasoned expert, the company has proven experience and solutions to help them satisfy functional safety conditions and certify designs while lessening cost, risk and development time.


As well as the functional safety packages, it provides a TÜV SÜD-certified design tool package for its MPLAB development tools ecosystem to ease tools qualification. This includes a TÜV SÜD-certified MPLAB XC functional safety compiler with the TÜV SÜD certificate, a functional safety manual for the compiler along with safety plans and complete tools classification and qualification reports for the compiler, MPLAB X IDE, MPLAB Code Coverage and all MPLAB development ecosystem programs. It also providers Functional Safety Ready CAN FD and LIN transceivers and other companion devices, incorporating voltage supervisor devices, which can be employed with the functional safety ready DSCs and MCUs in a broad range of automotive applications.


“As the level of sophistication and electronics increases in cars, functional safety requirements are becoming much more rigorous in automotive designs. To help our clients develop safety applications quickly with minimal risk and on budget, Microchip has greatly expanded the offering of certified safety documentation and diagnostic self-test libraries, development tools and technical support,” said Joe Thomsen, vice president of Microchip’s MCU16 business unit. “As a key supplier in the automotive market, we will continue to expand our functional safety support to give our clients a competitive advantage.”


“As an accredited certification body for Functional Safety, TÜV Rheinland offers independent audit, verification, assessment and certification services relating to ISO 26262 and IEC 61508 that stand by quality and safety,” said Thomas Steffens, head of the certification body for functional safety and cyber security at TÜV Rheinland.


“As a result of our assessment based on our certification program according to ISO 26262, we confirm that the Safety Diagnostic libraries for the dsPIC33C DSC series from Microchip comply with the requirements of ASIL C. The diagnostic libraries can be used in automotive safety-related applications targeting up to ASIL C.”


The ISO 26262 functional safety ready dsPIC33C DSCs, and PIC18 and AVR MCUs are supported by the TÜV SÜD-certified MPLAB XC16 and MPLAB XC8 functional safety compilers (SW006022-FS and SW006021-FS), the MPLAB Code Coverage tool (SW006026-COV), MPLAB X IDE, MPLAB development ecosystem debugger/programmers and the safety documentation package to make the tool qualification effort easier.
