28C010T
1 Megabit (128K x 8-Bit) EEPROM
The software data protection function is to prevent unintentional programming caused by noise generated by external circuits.
In software data protection mode, 3 bytes of data must be input before write data as follows. These bytes can switch the non-
protection mode to the protection mode.
Software data protection mode can be canceled by inputting the following 6 bytes. Then, the EEPROM turns to the non-protec-
tion mode and can write data normally. However, when the data is input in the canceling cycle, the data cannot be written.
