Working Principles

The AT45DB161B-CNC utilizes a serial peripheral interface (SPI) to communicate with the host microcontroller or system. It stores data in non-volatile memory cells, which retain information even when power is disconnected. The chip select (/CS) pin is used to enable communication with the IC, while the serial clock (SCK) synchronizes data transfer. The serial data input (SI) pin receives data from the host, and the serial data output (SO) pin transmits data back to the host.
