TMS570LS3137-EP: MCU Selection.

Kadir ÇIÇEK

Part Number: TMS570LS3137-EP
Other Parts Discussed in Thread: TMS570LS3137

Tool/software:

Hello : 

We need a microcontroller for avionic application with falloving requirements. 

Could you suggest us MCU part numbers. 

Basicly we need small  , -55 +>100 operating temperature range, memory is above average, ECC code correction for D0-178 Considerations

I can't say that I know the differences between different series such as ARM, C2000 ,Hercules and others .if you could specify if there is a distinction based on application type for these series or on what basis the selection is made.

I try to search from TI and Digikey but , I'm not sure I'm not sure I've explored all the options. 

I would appreciate it if you could share resources that will help us for product selection.

If any other necessary details are needed to make the choice, feel free to ask.

If there is an application engineer in the Turkey/Middle East region that we can ask these questions and hold a meeting with if necessary, maybe we can make the selection easier this way.

thank you for support 

Core Size 32-Bit Single-Core

    Hi,

      If Operating Temperature (-55C to 150C) is a must-have requirement then TMS570LS3137-EP is the only one that will meet your requirements, It has ECC protection for flash, SRAM as well as some peripheral RAMs. The rest of peripherals such as UART, I2C and SPI are pretty basic that most MCUs on the market will support. Having said that TMS5703137-EP does not come with <100 LQFP. It only comes with the BGA package. 

      Please use the product selection website with filters to filter out other MCUs may meet your requirements. As mentioned, if -55C is must-have requirement then TMS570LS3137-EP is the only choice. if not, there are more choices of MCU that support ECC for memories.

    Hi Charles ; 

    Actually I didn't get the answers I expected. I would wish you to come back with a little more work. I cannot set up a temperature or ECC filter on the site you forwarded.

    I was able to find TMS320F28377DPTPEP-ND alternative product by scanning Digikey. But we still do not have a faster method than opening datasheets one by one. My methot is like try to finf a black cat in a coal mine :)

     Can you answer my previous questions (below) 

    I would appreciate it if you could share resources that will help us for product selection.

    If any other necessary details are needed to make the choice, feel free to ask.

    If there is an application engineer in the Turkey/Middle East region that we can ask these questions and hold a meeting with if necessary, maybe we can make the selection easier this way.

      Regards.

    Hi,

     You can select Operating Temperature Range to view the temperatures. As I have mentioned, only TMS570LS3137-EP will meet your -55C requirement. The major difference between a TMS570LS3137 and TMS570LS3137-EP is that the -EP has different package and temperature rating for high reliability applications. Otherwise, they are functionally the same. All other part numbers can only support -40C. As far as ECC, all of them have ECC protection for memories and they are functional safety compliant to IEC61508 SIL3. Refer to the certification. https://www.ti.com/lit/spnq005

    I do not support TMS320 MCU and have no experience with the product offerings. However, You can use the same filtering method for C2000 products.

    Please send me your full name and company info privately. I'm only supporting technical questions on e2e public forum. I can try to see if any regional FAE who can assist.
