Working Principles

The 93LC86C-I/SNG utilizes EEPROM (Electrically Erasable Programmable Read-Only Memory) technology to store and retrieve data. It employs a serial communication interface (SPI) to facilitate data transfer between the microcontroller and the IC. During write operations, data is sent from the microcontroller to the IC via the Serial Data Input (SI) pin. The IC then stores the data in its non-volatile memory cells. During read operations, the stored data is retrieved from the IC and transferred to the microcontroller via the Serial Data Output (SO) pin.
