Working Principles

AT25PE40-SSHN-T utilizes the Serial Peripheral Interface (SPI) protocol to communicate with the host device. It stores data in non-volatile memory cells that retain information even without power. The memory is organized into sectors, which can be individually erased and written. The chip select (/CS) pin is used to enable communication with the device, while the serial clock (SCK) and serial data lines (SI/MOSI and SO/MISO) facilitate data transfer.

Detailed Application Field Plans

AT25PE40-SSHN-T finds applications in various electronic devices, including but not limited to: - Microcontrollers - Embedded systems - Industrial automation equipment - Automotive electronics - Consumer electronics
