OPP's and temperature range

Other Parts Discussed in Thread: OMAP3530

Hello, I'm currently evaluating which CPU to use for a new design.

 I've been looking at the OMAP3530 as a possible candidate and I have some questions about issues that are not clear in the datasheet. My design requires industrial temperature range. Acorrding to the datasheet OPP5&OPP6 are not supported for industrial temp. range but then there is the following comment:

 "*If an extended temperature device is operated such that Tj never exceeds 90C (-40°C £Tj £ 90°C) then the OPP POH limits for commercial devices indicated above apply."

 This leaves me somewhat confused. So what I want to know is this - if I use the OMAP3530DCUSA and make sure that my design does not go above Tj>90C can I use OPP5? I also see the 720MHz Cortex is never offered for devices with extended temp. range. Is this due to the fact that OPP6 isn't supported for temp. range above 90C? If I make sure my design doesn't go above Tj above 90C does TI offer any product that can work at 720MHz?

 

 Looking forward to hear from you,

 Elad

    OPP5 can only be used when Tj<90C.  That does not mean that the part cannot run at higher temp in a lower operating mode.  However, as long as part is in OPP5, Tj must be kept below 90C.

    TI does not offer a version of OMAP3530 that supports 720MHz below 0C.  720MHz(OPP6) is only supported from 0-90C in *72 parts.  Extended temp parts are only tested at 600MHz and 720MHz performance cannot be guaranteed.
