Re: [beagleboard] operating temperature range of Beaglebone Black

2014-11-20 Thread Michael Wood 
David, I fully understand. I previously went through the markings on the
parts I can read with 10x magnification, but a few elude me (hence my
original question). Y4 markings read:

0245760 (freq)
DCP1423 (?)
2643 (date/batch code?)

The ASDMB datasheet suggests an ASDMB, and the ILSI datasheet clearly
shows an ILSI on the part. So the only part left is the
ECS-2033-24.576-B? Seems odd.

Thanks guys. I'm not worried, this shouldn't be hard to figure out.

 Bingo. This is just what I needed.

 FYI, and as we all know, some parts are pretty tough to read anything off
 of, and even if you get something it might only be a batch/date code.

 Robert this is just for development of course, trying to figure how to
 leverage the fantastic open source design while modifying it to our specs
 (low temp, obvi) before spinning off our own board. I wouldn't ask a
 consumer/hobbyist dev board to be industrial grade by any definition.

 Thanks both!

Gerald, do you have any more info on that? Occasionally I'll see someone
who's trying to do it, but rarely someone who *has.*

FYI for the community, CircuitCo sales offered me a BBB clone with all
components rated to -40 C except the LEDs which are rated to -20 C, for $89
in low qty. Actually getting one may be the challenge.

Thanks again.

Gerald, can you point us to the *exact* BOM for BBB-C? We see a *general* 
BOM on the wiki that lists a few different p/n's for many designators (e.g. 
Y1), but each of those p/n's may have a different temperature range. Makes 
it tough to know *which* parts are holding the BBB-C back from (say) good 
low temp reliability.

That is the BOM we publish. Those are the real part numbers. You need to go

Re: [beagleboard] operating temperature range of Beaglebone Black

2014-11-19 Thread Michael Wood 
Gerald, thank you for distinguishing between real and non-real (divide by
-1?) part numbers and for explaining how google ([p/n] datasheet) finds
datasheets :) But that doesn't answer my question.

E.g. Y4 has three different part number options
1. ASDMB-24.576MHZ-LC-T (-40 to 85 C)
2. ECS-2033-24.576-B (-10 to 70 C)
3. ISM95-3161BH-24.576 (0 to 70 C)

If I want to modify my BBB-C for operation down to -40 C do I replace Y4 or
not? I don't know, because I don't know *which* Y4 is on the board. If no
one knows (or you're not telling) what exact parts CircuitCo sent through
the reflow oven, please just say so. Thats a fine answer.

Sorry for the snark, but stating the obvious is discourteous and a waste of
our time.

Re: [beagleboard] operating temperature range of Beaglebone Black

 Gerald, thank you for distinguishing between real and non-real (divide by
 -1?) part numbers and for explaining how google ([p/n] datasheet) finds
 datasheets :) But that doesn't answer my question.

 E.g. Y4 has three different part number options
 1. ASDMB-24.576MHZ-LC-T (-40 to 85 C)
 2. ECS-2033-24.576-B (-10 to 70 C)
 3. ISM95-3161BH-24.576 (0 to 70 C)

 If I want to modify my BBB-C for operation down to -40 C do I replace Y4 or
 not? I don't know, because I don't know *which* Y4 is on the board. If no
 one knows (or you're not telling) what exact parts CircuitCo sent through
 the reflow oven, please just say so. Thats a fine answer.

Probably the one that was in the reel at production time of the board in hand

 Sorry for the snark, but stating the obvious is discourteous and a waste of
 our time.

The board was not built for your environment. The BOM is
available, go thru it and update all the components you need for the
temp rating and go spin your own board.

Otherwise, just pop off that oscillator and replace it with one that
meets your temp..

2014-11-19 Thread David Funk 
What are the markings on the part???  That's what I look at when I
determine what parts are installed.

You may have to dig through all the data sheets on all the allowable parts
in the BOM for that part to find what you want, but you are the one that
wants to change things, you need to do the due diligence.

 That is the BOM we publish. Those are the real part numbers. You need to
 go a look them up to find the datasheets. Every part number used was
 commercial grade.

 Gerald, can you point us to the *exact* BOM for BBB-C? We see a
 *general* BOM on the wiki that lists a few different p/n's for many
 designators (e.g. Y1), but each of those p/n's may have a different
 temperature range. Makes it tough to know *which* parts are holding the
 BBB-C back from (say) good low temp reliability.

 Hi,

 I could not find in SRM discussion of the rated operating

 In SRM Rev A5A I see that the AM3359 processor is rated for -40 to
 90 degrees C.  Micro's page
 http://www.micron.com/parts/nand-flash/managed-nand/mtfc2gmtea-wt
 says mtfc2gmtea-wt is rated for -25 to 85 degrees C. I suppose there 
 might
 be tighter constraints from other components.

 Thanks in advance!

Bingo. This is just what I needed.

FYI, and as we all know, some parts are pretty tough to read anything off
of, and even if you get something it might only be a batch/date code.

Robert this is just for development of course, trying to figure how to
leverage the fantastic open source design while modifying it to our specs
(low temp, obvi) before spinning off our own board. I wouldn't ask a
consumer/hobbyist dev board to be industrial grade by any definition.

Thanks both!

Good luck!

BTW, someone has already done this and have a BOM already done. They have
actually built and shipped an industrial version of the board.
