Working Principles

The CY14B101Q2A-SXIT is based on Serial NOR Flash technology. It utilizes a grid of memory cells, each capable of storing one bit of information. These cells are organized into sectors, allowing for efficient read, write, and erase operations.

During read operations, the device receives commands and addresses from the microcontroller via the SPI interface. The requested data is then retrieved from the memory cells and transmitted back to the microcontroller.

Write operations involve sending commands, addresses, and data to be programmed into the memory cells. Erase operations clear entire sectors, making them ready for new data storage.
