Working Principles

The AT25040N-10SI utilizes the Serial Peripheral Interface (SPI) protocol to communicate with the host microcontroller. It stores data in a grid of memory cells that can be electrically programmed and erased. When data is written, the memory cells are selectively charged or discharged to represent the desired information. During read operations, the stored charge in the memory cells is sensed and converted back into digital data.

Detailed Application Field Plans

The AT25040N-10SI finds applications in various fields, including: - Microcontroller-based systems - Automotive electronics (ECUs, infotainment systems) - Consumer electronics (smartphones, tablets, wearables) - Industrial automation and control systems - Medical devices - IoT (Internet of Things) devices
