Working Principles

The AT25128N-10SI utilizes flash memory technology to store data. It employs a floating gate transistor structure that allows for non-volatile storage of electrical charges. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be read back later, providing reliable data storage.

Detailed Application Field Plans

The AT25128N-10SI finds applications in various fields, including: 1. Consumer electronics: Used in smartwatches, digital cameras, and portable media players for data storage. 2. Automotive: Employed in automotive control units for storing calibration data and firmware updates. 3. Industrial automation: Utilized in programmable logic controllers (PLCs) for storing configuration parameters and program code. 4. Medical devices: Used in medical equipment for storing patient data and device settings.

Detailed and Complete Alternative Models

1. AT25256N-10SI: Similar to AT25128N-10SI but with double the storage capacity (256 kilobits).
2. AT25064N-10SI: Lower capacity variant with 64 kilobits of storage.
3. AT25320N-10SI: Higher capacity variant with 320 kilobits of storage.

These alternative models provide options for different storage requirements while maintaining similar functionality and characteristics.
