Working Principles

CY14E256Q1A-SXI is a NOR flash memory IC that stores data using floating-gate transistors. It utilizes the Serial Peripheral Interface (SPI) for communication with the host microcontroller or system. The memory cells are organized into sectors, which can be individually erased or programmed. Data is written by applying high voltages to the appropriate memory cells, and read by sensing the voltage levels stored in the cells.
