What is X1286?

This is Intersil Real Time Clock/Calendar/CPU Supervisor with EEPROM X1286.

EEPROM stands for Electrically Erasable Programmable Read-Only Memory. It is a type of non-volatile memory that can be electrically erased and reprogrammed. EEPROMs are used to store small amounts of data that need to be saved even when the power is turned off, such as the settings of an electronic device or a small amount of code that needs to be retained after a power cycle.

[ Detailed Data ]

EEPROMs are similar to EPROMs (Erasable Programmable Read-Only Memory) in that they are both non-volatile memory that can be programmed, but EEPROMs can be reprogrammed electrically, while EPROMs must be erased using ultraviolet light before they can be reprogrammed.
