Problems with chips from the TAIWAN foundry.

​I am having problems with an Altera Cyclone III FPGA. We have been using this part for several years without problems. However, now we are getting parts that are source from the TAIWAN foundry which...

Hi Stanley,

May i know how many unit you received is not working properly? I would suggest to go for ERMA process. Meanwhile for the part source, apologize that we distribute it to our distributor. If you have any concern such as to get part sourced from Korea only, i would suggest to work with your FAE / distributor for this.

Regards,

YL

* At this time we have 4 failing units in house and 2 at customer installations. All 4 in house units have a TAIWAN foundry mark with the date codes: GBCAAA1507E NCAAA54572 3N90GE5C00 and GBCAAA1825E VCAAA78752 3P9GE8N00 We have one unit with the lower date code that works properly. I wanted to get a FPGA from the KOREA foundry to replace on one of the failing units, to see if it would fix the problem. We have not seen any issues with units that have a FPGA with a KOREA foundry mark. Our FPGA logic has four identical frequency dividers that divide a 500,000 Hz clock down to 100 Hz. One of these 4 dividers will on average miss counting 20% of the pulses. The other three dividers work properly. Our distributor has no control over which foundry his parts come from. I don't know who my FAE would be. How do I find out? Thanks Stanley Wawrowski
