TMS570LC4357-SEP: Clarification on SEU Data Availability

Tomohiro Tanaka

Tool/software:

In the linked discussion, it was mentioned that SEU test data for the TMS570LC4357-SEP is available in document SPNA249. However, while this document includes information on SEL, it does not appear to contain any data or discussion related to SEU.
Would it be possible to obtain a separate report specifically addressing SEU for this device?

We don't SEU report for TMS570LS3137 device. But we have SEU test report for TMS570LC4357-SEP BGA package

Tanaka-san,

Thanks for reaching out to TI. If I follow the earlier thread I arrive at this post; https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/90468/tms570-avionics-seu-statistics

This post is the one that mentions SEU data; this post, however, is not in the context of the -SEP device or data taken for the SEU/SEE report. Rather, the SEU data mentioned in this thread is something that is a part of our safety package for this device(available under NDA); which is using simulated data along with your mission profile to give soft error prediction for the device. If you are interested in this package, I can loop in some others to see what's the right path forward.

The safety manual can be found here; https://www.ti.com/lit/fs/spnu620a/spnu620a.pdf

Outside of the above, the SEU report you link for the -SEP device is the only targeted SEP test dataI am aware of for this device.

Best,

Matthew

Tanaka-san,

Apologies for the delay, we may need to take this discussion off-forum. In order to share this info I believe we need to have NDA in place between TI and your company. Let me know if you want me to initiate something on the private chat feature.

Best,

Matthew
