Hi, members.

I'm a chief engineer in charge of developping information display with touch faunction.

And my team are developping fat stylus pen that can communicate with touch panel.

Actually though under mas production, STM chips are short for further plan.

If you know who has a plenty of stock of them, please tell me immediately. 

I appreciate your help.

Hi,

I found this chip available, but 8 pins are not included...

do you use any of these missing pins ?

http://www.digikey.com/product-detail/en/stmicroelectronics/STM32W108HBU64TR/497-11414-1-ND/2679625

can you source another chip like this one ? what part number ?

do you have the source code for IEE84 ?

this is not an easy issue to recover from.

it is far better if you can source the original chip.

I am happy to help where I can, although I am a Mature engineer, I am still a beginner in C coding,

you will need support from a more experienced engineer like Clive...

this chip looks to have the hardware capabilities, but the pins are not aligned.

maybe you can look into that option as something to get you out of trouble.

but long term, you would be far better to have your own source code and select any chip that suits.

Dear Mr.Nick,

Sorry for my late response.

Thank you for your additional adivice.

As you mentioned, the difference between STM32W108HBU64TR and STM32W108CBU64TR are number of pin and package size mainly.

And we have to product a new board to mount a new chip. Then a lot of tasks will occur.

If we will develop a new system, I would like to adopt your idea as alternative.

I appreiate your advice sincerely.

Best Regards,

Masanori Toyoda

I just read through this conversation.

Have you been in direct contact with your STMicroelectronics representative? The FAE's in our area are great at helping to solve problems.

Instead of spinning a new board to accommodate a different chip with a different pinout, why not use a carrier. Mount the replace chip on a daughter card/carrier and then mount that assembly on you current board. This could buy you time to develop a new board a go through the full development, prototype, debug, manufacturing cycle.

Just thinking out loud.

Dear Toyoda San,

Unfortunately this product was terminated. ST is not in a position to manufacture this product anymore. There might be stock at local distributors, but no product left in ST warehouse. 

If you are located in Japan, I recommend that you contact our sales office in Tokyo or Osaka to check whether they can help. Contact details are on st.com

Dear Vera-san,

Thank you for your advice.

Actually we have serched whether there are stock of the device in Japan, US, and china so on.

I could get about five hundred pieces only.

Thanks.

Dear Richard-san,

Thank you for your advice.

Actually we have already mas-produced this product with this chip.

Then we can't add anything for current model withiout new Authentication.

We could not contact ST diectly because our local agent would not forgive us it.

Actually they are helping us instead of ST. Unfortunately the valid result is none for us.

I appreciate yor help and coopeation.

Best Regards,

Masanori Toyoda

Did your local agent not tell you way back when that the component

you're so desperately looking for was obsolete?

If they failed to tell you, then they should be paying for the costs to

re-design the product with a supported and current product.

I wish you all the best.

Dear Richard-san,

Thank you for you idea.

Unfortunately, it is our mistake that has fallen into this situation.

Our local agent told us that they would be discontinued in 2015.

Thanks.
