Working Principles

The AT17C65-10PC uses floating-gate technology to store data permanently. During programming, a high voltage is applied to the selected address, causing electrons to tunnel onto the floating gate. This process traps the charge and determines the stored data. Once programmed, the data remains intact until the end of the device's lifespan.

Detailed Application Field Plans

The AT17C65-10PC finds applications in various fields, including: 1. Microcontrollers: Used to store firmware, configuration data, and lookup tables. 2. Embedded Systems: Provides non-volatile memory for critical system parameters and calibration data. 3. Consumer Electronics: Used in devices like TVs, set-top boxes, and gaming consoles to store configuration settings and user preferences.

Detailed and Complete Alternative Models
