I also panicked seeing note on Digi-Key. I design product using LPC1768FBD100,551 and its ready to mass manufacturing in couple of month. In Digi-key site they says LPC1768FBD100,551 is Discontinued and they suggest alternative LPC1768FBD100K. I tried to find the difference between LPC1768FBD100,551 and LPC1768FBD100K. But didn't find any solid difference between both Products. Please let me know what is the difference. Also please let me know is LPC1768FBD100K 100% compatible with LPC1768FBD100,551 product designs.
the only difference between LPC1768FBD100K and LPC1768FBD100,551 is packaging.
the chip itself is the same.
BTW, this thread is too old, if you have new question, please create a new thread thus more support engineers can see it.
Have a nice day
