Working Principles

The W25Q80BWSVIG TR utilizes the Serial Peripheral Interface (SPI) protocol to communicate with the host device. It stores data in non-volatile memory cells, which retain information even when power is removed. The device uses a combination of floating gate transistors and charge storage techniques to store digital data as electrical charges.

During read operations, the chip receives commands from the host device via the SPI interface and retrieves the requested data from the memory cells. Write and erase operations involve modifying the electrical charges in the memory cells based on the received data and commands.
