I have a product which uses a 24LC16, a customer has returned one because it cannot retain one of its settings. It appears that the eeprom is failing on one byte. Has anybody seen this before?? I have made over 100 of these and this is the only one showing these symptoms. Martin -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
