The software in the SafeTI software packages is UL-certified, as recognized components, to the UL 1998:2008 Class 1 standard, and is compliant with IEC 60730-1:2010 Class B, both of which include home appliances, arc detectors, power converters, power tools, e-bikes, and many others.
The SafeTI software packages are available for select TI C2000 MCUs and can be embedded in applications using these MCUs to help customers simplify certification for functional safety-compliant consumer devices. Because of the similarity of the two standards, the IEC 60730 software libraries can also help assist customers developing consumer applications compliant with the IEC 60335-1:2010 standard.
The software packages include ready-to-run, simple application examples with software libraries UL-certified, as recognized components, for select TI C2000 MCUs, and can be downloaded from the SafeTI software folder, along with supporting safety manuals and user guides. The software library allows for embedding a variety of system tests required by IEC 60730 and UL 1998, which are described in the supporting safety manual. Projects built with the software library demonstrate how to create power-on self-test (POST) and periodic self-test (PST) with reporting conducted through a UART peripheral connection. The user’s guide demonstrates how to integrate the testing into functional safety consumer application designs. The C2000 MCUs include a special hardware element – parallel signature analysis (PSA) – that allows for a 40-bit cyclic redundancy check (CRC) of the data bus on a cycle-by-cycle basis for additional safety without affecting the main CPU or software application.
The software package includes UL-certified software libraries and example projects ready to run on controlCARD-based hardware, a user manual and a safety manual to help speed development for many consumer products requiring IEC 60730 and UL 1998 standard compliance or certification.
The software is compatible with the Delfino F2833x and F2832x MCUs that provide up to 150 MHz of floating-point performance and integration to real-time control applications. The DSP-based C28x core simplifies development and delivers high performance for demanding real-time applications. It can also be used with the Piccolo F2806x, F2805x, F2803x and F2802x MCUs provide up to 256 KB of low-cost, high integration, 32-bit performance, featuring architectural advancements and enhanced peripherals. There is additional flash memory and control law accelerator (CLA) for high-efficiency control loops on the Piccolo F2803x series, increased analog integration on the Piccolo F2805x series and floating-point unit plus Viterbi complex math unit (VCU) of the Piccolo F2806x series.
SafeTI software packages for use in consumer products needing functional safety certification to UL 1998 and IEC 60730 standards using TI C2000 MCU designs are available today without charge, fee or use royalties. C2000 MCUs supported start at $1.91 in 10 ku orders. Designers can begin evaluating their designs immediately with any of the available controlCARD based experimenter’s or application-specific development kits, starting at $99.
