Working Principles

The 93C76C-I/P is based on the principles of electrically erasable programmable read-only memory (EEPROM). It utilizes a floating gate transistor structure to store and retrieve digital information. The memory cells are organized into an array, and each cell can be individually addressed for reading or writing operations. Data is written by applying a high voltage to the control gate, which traps charge in the floating gate. Erasing is achieved by removing the trapped charge using an electrical pulse. The stored data can be accessed serially through a microcontroller using the provided SPI interface.
