TM4C1237H6PZ with Resonators 8.000MHZ

Hello Phuchit,

The ppm nor the max power dissipation is clear for this part. The PPM setting is rather important for USB to work properly.

You would need to check that the value for the above two parameters comply with

Electrical Specification for Main Oscillator Specifications as per the data sheet.

@Amit,

Good for you - believe it "normal/customary" that you applied, "some bounds" to this user/client "unique application" question!

If such limitations are not emplaced - "Where, when, and how will, "questions targeting "every single" MCU supporting component be managed?  Poster here seems not to have, "dug too deeply" - our tech firm's read is such investigation is clearly, "his responsibility!"

In an "ideal world" your firm would provide a "well noted" listing of such, "suitable, critical components" - which would substantially eliminate such forum questions - while well guiding your client/users to, "known/safe harbor..."

Minus recognition & acceptance of the clear value of, "known/promoted/enforced" forum, "Rules/Regulations" you/others here are forced to examine, evaluate and deal with each post uniquely!  Is this efficient?  Is it the best use of your time/effort?  (I can report that in co-founding/taking past tech firm public - such avoidable repetition was not deemed, "best practice!")

Hello cb1,

The Electrical Section does give the list of crystal part numbers which have been tested for TM4C123. Yes, i do agree that this list is not exhaustive, thus we have supported the equations need to select a part out of the non-listed crystals and which should be OK to work with the TM4C devices.

I would rather not say a "yes" to the user if the required data to me seems insufficient and let them be on the receiving end of a USB failure as in the example.

@Amit,

Some here truly have your best interests at heart - react when (fairly simple) things seem (to us) inefficient and/or harmful.  Note that we do have some past record of high success - thus believe our suggestions may often have some merit.

Note that your answering post made little effort to steer the client to the, "suggested listings."  At minimum - I'd have vectored client to those pages.  (again - saves (often needless) wear/tear upon you...)  Recall we're not told "why" client has "selected" his particular device.  And - may not certain of those (client) selection criteria prove imperfect?

I don't believe the issue lies in, "saying yes" - but instead in creating & following a more stylized response method - which imposes some, "conformance behavior" upon posters...

Hello cb1,

Point taken and duly noted (a second time). I agree steering users in the right direction is important and should have made it clear in the fist reply itself.

Regards

Amit
