Working Principles

The W25Q32JVDAIQ TR is based on Serial NOR Flash technology. It utilizes a Serial Peripheral Interface (SPI) for communication with the host device. The memory cells store data using floating-gate transistors, which retain their charge even when power is removed. This non-volatile characteristic allows the device to retain data for extended periods without requiring constant power supply.
