Working Principles

The N25Q016A11EF640E flash memory utilizes the Serial Peripheral Interface (SPI) to communicate with the host device. It stores digital information in non-volatile memory cells, which retain data even when power is removed. The SPI interface allows for high-speed data transfer between the chip and the host device.

To write data, the chip erases the targeted sector and then programs the new data into the erased area. The write protection feature ensures that accidental modifications or deletions are prevented. The chip's low power consumption makes it suitable for battery-powered devices.
