Working Principles

The AT25128-10PC-1.8 utilizes non-volatile memory technology to store data in an array of floating-gate transistors. The data can be written or read using the Serial Peripheral Interface (SPI) protocol. When data is written, the device applies a high voltage to the selected memory cell, trapping charge in the floating gate. This trapped charge determines the stored data. During read operations, the device detects the presence or absence of charge in the memory cells to retrieve the stored data.

Detailed Application Field Plans

The AT25128-10PC-1.8 is commonly used in various electronic systems that require non-volatile memory storage. Some application fields include: - Consumer electronics: Smartphones, tablets, digital cameras, etc. - Automotive: Engine control units, infotainment systems, etc. - Industrial automation: Programmable logic controllers (PLCs), sensors, etc. - Medical devices: Patient monitoring systems, medical imaging equipment, etc.
