Question:
What about the distribution of application notes, usage notes, and malfunctions?
Answer:
Distribution of application notes
All EEPROMS, including ours, may malfunction (false-writes may occur) due to an “operation in a low-
voltage region upon power-on/off” or “improper recognition of a command due to a noise signal.” This
defect is particularly common in the voltage region of the microcomputer transmitting commands to the
EEPROM, where the voltage is lower than the lowest operating voltage of the microcomputer.
To prevent this defect, usage notes have been prepared for the EEPROM.
