TMS570LS3137: Differences with TMS570LS3137-EP

Shiromini Satkunarajah
Intellectual 320 points
Part Number: TMS570LS3137

I would like to know the differences between TMS570LS3137-ZWT and TMS5703137CGWTMEP. I ask this because I am only interested in TMS570137CGWTMEP as it has the temperature range between -55°C and 125°C but I couldn't find a development kit with this microcontroller. Please let me know if there is a development kit for this microcontroller. I was only able to find a development it for TMS570LS3137-ZWT (Hercules TMS570LS31x/21x Development Kit). According to the datasheets for TMS570LS3137 and TMS570LS3137-EP, these two microcontrollers have the same functions and pins as far as I can see.

    Hello Shiromini,

    These two devices are pin to pin compatible, and have the same peripherals, same memory (SRAM, Flash), etc. TMS570LS3137-EP is an enhanced product to supports defense, aerospace and medical applications.

    We don't have separate EVM for this device. You can use HDK for ZWT package for SW development.

    Hello Shiromini,

    I would also encourage you to post this question to the HiRel E2E since they would have better insight into all of the potential differences and if they offer any EVMs or recommendations given the different part number.
