Working Principles

The 24LC32AT-I/SNG utilizes an array of floating-gate transistors to store digital information. When data needs to be written, a high voltage is applied to the gate of the selected transistor, causing electrons to tunnel onto or off the floating gate. This process alters the threshold voltage of the transistor, representing either a logical "1" or "0". During read operations, the stored charge on the floating gate is measured to determine the stored data.

Detailed Application Field Plans

The 24LC32AT-I/SNG can be used in various applications, including but not limited to: - Embedded systems - Industrial automation - Automotive electronics - Smart home devices - Medical equipment - Consumer electronics
