Working Principles

The AT45DB041E-SHNHT-T is based on the Serial Peripheral Interface (SPI) protocol. It utilizes a combination of floating gate and tunnel oxide technology to store data in non-volatile memory cells. The memory is organized into sectors, with each sector consisting of multiple pages. Data can be written, read, and erased at the sector level, providing flexibility for various applications.

During operation, the chip select pin (/CS) is used to enable communication with the device. The serial clock (SCK) synchronizes data transfer between the microcontroller and the memory. The serial data input (SI) pin is used to send commands and data to the memory, while the serial data output (SO) pin transmits data from the memory to the microcontroller.
