Working Principles

The XC17256EPD8C is based on Electrically Erasable Programmable Read-Only Memory (EEPROM) technology. It utilizes floating-gate transistors to store and retrieve data. When a write operation is performed, the charge on the floating gate is altered, representing either a "0" or a "1". The stored data can be read by applying appropriate voltage levels to the address inputs and enabling the output buffers.

Detailed Application Field Plans

The XC17256EPD8C is commonly used in various electronic devices that require non-volatile memory storage. Some typical application fields include:

1. Embedded Systems: Used for program storage in microcontrollers and other embedded systems.
2. Consumer Electronics: Found in devices like digital cameras, printers, and set-top boxes for data storage purposes.
3. Automotive Electronics: Utilized in automotive control units for storing calibration data and firmware.
4. Industrial Automation: Employed in industrial control systems for storing configuration parameters and log data.

Detailed and Complete Alternative Models

1. XC1765EPC8C: Similar specifications but with a smaller memory capacity of 64 kilobits.
2. XC1736EPL8C: Offers the same memory capacity but in a different package (PLCC-8).
