Errata SM320F2812

TMS320F2812: Difference between TMS320 and SM320

Part Number: TMS320F2812
Other Parts Discussed in Thread: SM320F2812,

Hello Team,

My customer would like to know the difference between prefix TMS320 and SM320? He found the e2e thread below 

https://e2e.ti.com/support/microcontrollers/c2000/f/171/t/470862?Errata-SM320F2812

Stating that "The SM320 device is the same design as the TMS320 device.  The difference is in qualification, testing, burn-in, process control during production, etc." Do we have documentation about this? They didn't exactly mention which qualification test process.

Regards,

Renan

    Renan,

    Thanks for reaching out to the TI E2E forums.  That statement you've linked is essentially correct, I'll expand a bit below.

    I'll link to this document that gives the decoder ring to TI's High Reliability part numbers  I've linked to the page that talks about the SM320F2812.

    In addition to that the key differences that I am aware of between the Military qualified part and the normal catalog version are as follows:

    1)Temp rating: SM320F2812 is rated from -55C to 125C where TMS320F2812 is -40C - 125C(in S rated temp version).

    2)Package: the SM320 is a ceramic TQFP vs the plastic of the commercial device.  In addition to the temp extension, I believe this is a hermetic package.  Among other things this would give an infinite storage/shelf life

    3)The Mil designation also give customer ability to order devices from same wafer lot, same date range, or devices built recently; all for a price adder

    4)Lead Finish: The leads on the SM320 are Gold, where the TMS320 are NIPDAU(Nickel Palladium Gold) 

    Best regards,
    Matthew
