Functional safety packages accelerate automotive design

The certified functional safety packages enable engineers to develop products to the ISO 26262 functional safety standard. The company offers ISO 26262 functional safety packages for dsPIC33C digital signal controllers (DSCs), PIC18 and AVR microcontrollers (MCUs).

The functional safety ecosystem for dsPIC33C DSCs includes AEC Q100 Grade 0-qualified functional safety ready dsPIC33C DSCs with dedicated hardware safety features, SGS TÜV Saar-certified ASIL B ready failure modes, effects and diagnostic analysis (FMEDA) report and a functional safety manual (FSM). There are also TÜV Rheinland-certified functional safety diagnostic libraries for designs targeting up to ASIL C, a functional safety reference application, with the steps required to develop compliant designs, and the collateral that must be generated for (ASIL B or ASIL C) compliance, together with functional safety analysis reports and certification reports for compliance and certification.

For the PIC18 and AVR MCUs, Microchip offers AEC Q100 Grade 1-qualified functional safety ready PIC18-Q84 MCUs with CAN-FD and AVR DA MCUs with LIN interfaces. Both have hardware support for capacitive touch sensors. The offeriing also includes SGS TÜV Saar-certified ASIL B ready failure modes, effects and diagnostic analysis (FMEDA) report and functional safety manual. There are also functional safety diagnostic libraries and ASIL B ready certificates and certification reports.

The functional safety packages are designed for use with the company's development tools to develop compliant systems. There are three ISO 26262 functional safety packages. The functional safety basic package offers basic resources like the ASIL B ready certified FMEDA and safety manual for designers to begin the evaluation of target functional safety levels and the design of safety-critical automotive applications.

For engineers at the next stage, there is the functional safety starter package, which offers ASIL B ready certified FMEDA and safety manual, a reference application and ASIL C compliant diagnostic libraries. This tool set is designed to help developers understand the ISO 26262-compliant development process and the reports that must be generated for compliance.

Beginners and seasoned engineers can use the third option, the functional safety full package to simplify the design and certification of safety-critical automotive applications. In additon to the starter package components, it also includes certified diagnostic libraries with source code and the associated safety analysis reports for designs targeting up to ASIL C.

In addition to the functional safety packages, Microchip offers a TÜV SÜD-certified design tool package for MPLAB development tools ecosystem, including 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 integrated development environment (IDE), MPLAB Code Coverage and all MPLAB development ecosystem programs. The company also offers functional safety ready CAN FD and LIN transceivers and companion products, such as voltage supervisor devices, which can be used with the functional safety ready DSCs and MCUs in a range of automotive applications.

 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.
