Abstract
A device, preferably an electronically calibrated sensor (100) includes a sensing element (102) with an output coupled to a calibration circuit (104). The calibration circuit (104) includes an electronically erasable programmable read only memory (EEPROM) (114). An EEPROM fuse (204) is employed in association with the EEPROM (114) which in a programming-disable logical state disables the write/erase program logic (208). The EEPROM fuse (204) may only be erased upon a valid fuse override signal (232) the input for which (224) in a final packaged device is inaccessible.
