Temperature range for MSP430F2618-EP

Other Parts Discussed in Thread: MSP430F2618

Hello Fellows,

Could you explain me  what is the temperature range of the MSP430F2618-EP. As soon as this MCU is  part of the enhanced products microcontroller I expect   that temperature range is -55...+125C

But if we look on the http://www.ti.com/product/msp430f2618-ep#samples  we find that temperature range is -40...105C

What is real temperature range for this part and what is the difference between MSP430F2618-EP and MSP430F2618 in the case if temperature range is the same? And why the temperature range is differ from the rest MCU from "Enhanced product" line? which have temperature range -55...+125C?

best regards,

Oleksiy

    From SLAS632 -- DECEMBER 2008.


    Storage temperature: Unprogrammed device . . . . . . . . . . . . . - 55 ºC to 150ºC
    Programmed device  . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .  - 40 ºC to 105 ºC

    Higher temperaturemay be applied during board soldering process according to the current JEDEC J-STD-020 specification, with peak reflow temperatures not higher than classified on the device label on the shipping boxes or reels.

    In case if temperature range is the same as for MSP430F2618 as for MSP430F2618-EP I don't see difference in the parameters which cause four time difference in the cost of the MSP430F2618-EP.

    COuld any one explain me the difference between MSP430F2618 and MSP430F2618-EP?

    best regards,

    It's indeed a bit strange that the temperature range is the same for the normal and the extended product.

    The difference between the two seems to be "only" these points:

    Datasheet said:
    SUPPORTS DEFENSE, AEROSPACE, AND MEDICAL APPLICATIONS
    - Controlled Baseline
    - One Assembly/Test Site
    - One Fabrication Site
    - Extended Product Life Cycle
    - Extended Product--Change Notification
    - Product Traceability
    - SnPb Solder Ball Alloy for Increased Reliability

     These things cost quite a lot as it's a substantial amount of work and documentation which has to be done additionally - and well if defense, aerospace or medical stuff is involved prices start to skyrocket, you're paying for enhanced reliability even if the devices are rock solid to begin with, some regulations require you to use qualified devices - just to cover your butt if something goes wrong.
