Hi friends of microcontrollers,
due to EOL of Fujitsu/Cypress MB91F467Cxxx we have the need grabbing
last items worldwide to maintain some industrial controllers.
Lastly we got some of them from different suppliers, all marked with an
extra number (e.g. 944 or 752). Does anyone know the meanings of these
extra markings? Main problems of the marked chips: Not programmable with
original flash tools, so we had to trash them after desoldering! A hard
decision for 100 and more items at 35 USD each ...
Any helpful hints are welcome
