Does TI have any micro-controller or processor supporting IEC60730 Class C safety application?

Other Parts Discussed in Thread: MSP430-IEC60730-SW-PACKAGE

I know that some MSP430G28xx series MCU support Class B level safety application. Class C level safety requires more strict self-check for the MCU used in such kind of application. For example, to guarantee the MCU works in healthy status, Class C application requires its MCU has the ability to check the instruction decoding to ensure that there is no error or fault happened in MCU instruction decoding procedure.

We are developing auto-burner control product which is required to pass software Class C certification test. To pass this test, we need to make the MCU used in our product doing Class C level self-check regularly. IEC60730-1_2013 Edition 5, H.11.12.2.4 Table H.1 gives the requirements for software Class C level self-check.

We are choosing proper MCU right now.

Does TI have MCU product matching our application?

Hi Weiran,

Unfortunately, MSP430-IEC60730-SW-PACKAGE can only support class B safety level. To meet software class C requirements typically you need to have a dual mcu architecture in your application.

You might be interested in looking at the Hercules MCU family since most of IEC60730 class C requirements are already implemented in HW. Below is a link to a white paper regarding how TI Hercules MCU family can assist you comply with IEC60730 requirements.
