Working Principles

The W25Q32JVTCIQ TR is based on the Serial Peripheral Interface (SPI) protocol. It utilizes a combination of floating gate and tunnel oxide technology to store and retrieve data. The SPI interface allows for fast and efficient communication between the flash memory and the host device.

When data needs to be stored, the memory cells are programmed by applying high voltage pulses to the floating gates. To retrieve data, the memory cells are read by sensing the voltage levels on the floating gates. The non-volatile nature of the memory ensures that the stored data remains intact even when power is removed.
